We've added the Pentax Q7 to our database of studio comparison images. The Q7 is the first Pentax Q-mount camera featuring a 1/1.7" sensor to match its enthusiast compact peers. These shots are also available from other reviews and the standalone tool (click 'Review Comparison Tool' link in the site's Reviews menu). We've already published a gallery of real-world samples, and we'll be adding a comprehensive review in the coming weeks but, in the meantime, click through to see how the Q7 stacks against the competition.

Our comparison tool allows you to compare our standard test scene at a variety of camera settings. First select a primary camera from the pull-down list in the gray central panel, then select the camera(s) you’d like to compare it to. Changing the ISO or image mode at the top of the page will affect all the selected cameras. Changing either parameter immediately above one of the zoomed-in previews affects only that specific camera. Click on the image below to open the comparison tool interface (opens in a new window).

Study sample test images of their arranged set by original Q with 01 standard prime lens - you will see that quality is going down towards edges and corners, with steep loss of detail.

This may be the nature of the lens with Q system, which for me does not reduce its value in usage.

I still want to know how much image circle the Q lenses cover! I mean, the previous one was a 1/2.33" sensor, this one is a 1/1.7" sensor. Is the next one going to be a 2/3" sensor that uses the same lenses? How much area does this system actually cover?

By the way, Pentax Q7 actually has ~1/1.74" sensor and this is Not 1/1.7" (!) since the sensor is 7.44 mm by 5.58 mm. The sensor is smaller than 1/1.7" sensor and here are data for 1/1.7" sensor:

Sensor Type: 1/1.7"
Aspect Ratio: 4:3
Image Circle Diameter: 14.941 mm
Diagonal: 9.500 mm
Width: 7.600 mm
Height: 5.700 mm

The correct term is 1/1.7"-type and there's some variance within each 'type.' For instance, not all 1/2.3"-type sensors are the same size.

That's right and I'm considering Nikon 1 J3. Also, Pentax's management really lost sense of reality when it comes to MSRPs. Here are examples:

Hello,
The photo is in my opinion bad due to lens defect.
Look at the center of photo. The chroma aberration would be in the center minimal and the character would be radial. On the photo the chroma aberration in the centre is linear so it is probably effect of bad justified inside lenses.
I have had similar defect in 02 lens and I have returned it to seller.

0 upvotes

I really worry about the lack of fine detail (hair, fur), but actually it has pretty exactly the same IQ as Samsung's EX2F, which was rated a pretty good camera here. Despite the soft jpegs. Are we all pixel peeping too much again?

But it's really not much better than a good 2.3" at low ISO... I can't deny I'm disappointed.

0 upvotes

The only way this system would make any sense if it had native macro and native extra long tele (maybe both in something like 30x+ zoom and fast - f/2 or faster - long tele zoom). Otherwise, Nikon 1 and even m43 are just as small, light and cheap while being incomparably better.

0 upvotes

if we define fast as we use for 35mm format lenses,
that is f/2.0 primes, then it's physically impossible
to have fast lenses for 1/1.7" sensors because that will be
f-number = 2.0 / 4.6 = f/0.44

the advantage of 1" sensor is that it's easier to make superzoom for videos but we'll have to wait for a new mount because Nikon 1 is not good.

The images are not merely a little soft but there's a several lack of detail... strange.
In the test by photozone.de ( http://photozone.de/pentaxq ) the lens was judged to be rather sharp, but they mentioned a decrease in IQ at close focusing distance.

If this is a lens issue it's hard to let Pentax/Ricoh off the hook. The lens costs $300 which is not a whole lot less than an MX-1 which delivers better test results (much better!) despite having a lens with a bigger zoom range. They CAN do better and should.

0 upvotes

There's a big difference between a lens being good and a lens being good at producing the best-possible results at full zoom and close focus distances.

Very few zooms are consistently good across their entire range and fewer still are up to this level of critical scrutiny - especially when shot at close focus distances.

I've not shot it, but it may well be fine in real world use.

0 upvotes

Lens in MX-1 was first seen in Olympus XZ-2 last year, I bet Pentax did not develop that. The same thing with lenses in WG-3 (TG-1), and WG-1/2 before that. And DA*50-135, only what was that, Tokina?
Pentax probably doesn't even have optical department anymore.

Ouch. I am a loyal Pentaxian, but I have to say that is very poor. The left side of the image looks like mush. The centre is unimpressive. Soft, soft, soft. And in the comments below, Richard Butler tells us that the much-heralded-by-the-fanboys 01 Prime was tested and it came out "considerably worse"!

C'mon Ricoh, kill this Quirky Quackers waste of your resources!

3 upvotes

You are apparently loyal to a brand, but not loyal to common sense. Did you kill yourself after the first failed driving test?
There are simply too many unknowns in this test to say anything definitely about the entire Q line. And that you and others want it eradicated tells more about you and those who are scared to think rationally.
To investigate, DPR could use:
a) another Q7 body,
b) a Q10,
c) original Q,
d) another 02 lens.

Etc. That's how a serious person conducts tests and draws conclusions.

I'll ignore the personal stuff, but oh yes: when it's the Q7, DPR should indeed take the time to conduct a thorough Sherlockian investigation of different combinations of other Q equipment. They are sure to come to a different conclusion. Perhaps that's because there's so many variables (highly variable variables, if this test shot is anything to go by) which might go wrong in a line which has self-professed 'toy lenses'.

Meanwhile - gosh! - all the other brands' cameras in the comparisons look fine! DPR must have gotten a lucky good copy of those then!

2 upvotes

Tosic is talking objectivity. You're talking attitude. There is no rational reason why having "toy lenses" in a camera's line of accessories would affect the quality or capabilities of the camera or of other lenses and accessories for the camera. Your attempt to stigmatize the whole Q line because Pentax made the (unfortunate, in my opinion) decision to name two of the lenses for it "toy" says plenty about your attitude and little about the actual quality and worthiness of the cameras and lenses.

If you dislike the Q and its lenses, why not just ignore them? Your attitude and sarcasm are neither helpful nor appreciated.

0 upvotes

I should have made myself clearer. The prime is considerably worse /in this particular situation/.

Using a 39mm equiv lens to shoot a scene where we usually use something in the 75-85mm equiv range means we're working /really/ close to the scene, which means you get dreadful corners (but better centre sharpness). But it's unusual to shoot at close distances and closely assess the corner detail.

We had similar difficulties with the Sony RX100 (its lens performance at close distances isn't representative of its real-world performance), which is why we're hoping to introduce our new test scene as soon as possible.

1 upvote

However, a reminder to Ricoh Imaging: re-issue the damn 01 and 02 lens, as told by so many Q users over the last 2 years! That statement is embedded in every other post in Pentax Compact camera forum.

Q thrives on fast apertures. For example, this incredible old man, Miyazaki San, has made MS Sonnetar 25mm/f1.1 for the Q. An independent optical engineer says the same message as the users. That's how you do it, and that what makes the Q system really shine.

Would anyone judge the D800's possible IQ with a test shot done with cheapest kit lens? On DPR, system cameras are tested with their 50mm equivalent good primes, or best ones that DPR has for the mount.

In the case of Q7, although it is a system camera, it was tested with the Q's so called kit lens. And the results also show focusing issues. The camera has an all new sensor, same as the MX-1, the results simply cannot be that bad and don't show what a Q7 can really do.

If the new test environment is going to be made, let's wait.

However, commenters have a full right to rant; this isn't what we'd we expect in any case. Ricoh Imaging, it's your call now — read the comment above about the 01 and 02 lenses.

Another comment, just to add my voice to the choir. Those samples are seriously very poor. Certainly wouldn't encourage a prospective buyer, in fact quite the opposite, it's really put me off it. They just can't be right with it's new sensor, must be a bad lens (but bad model or just a bad copy?).

On the plus side, it's a timely reminder just how good a job Nikon did with that P7700, at least on the IQ side. I remember being impressed with the real world samples you made with it and the studio samples bare that out. I'll have to check if it got a firmware update to iron out the quirks.

1 upvote

I hope Pentax-Ricoh engineers and managers will read it. The camera is full of inconsistencies and that is why I didn't buy it during my last visit to a local camera-store.

- It is Very overpriced. I've spent less money for Sony NEX-5N compared to any Pentax Q MSRPs
- Price-to-Square-Pixel Ratio is the Highest among almost all cameras ( it is calculated as follows: MSRP divide by 7.44 divide 5.58, where 7.44 and 5.58 are sensor dimensions in mm )
- In Manual mode with a Non Pentax lens ISO is limited to 1600 in Bulb mode (*)
- In Manual mode with a Non Pentax lens in Bulb mode the longest exposure is 2 seconds (**)
- Would I worry about all these color combinations? No
- Pentax claims that it is very popular in Japan. N/A here in North America since we have different living standards ( houses, apartments, cars, etc bigger )
- Why somebody should buy that camera for $500 when a Smartphone costs less than $150 and IQ is Not worse?

Please fix (*) and (**) and I''ll buy Pentax Q7.

This has better IQ than a cell phone. It is also much smaller than a nex-5n. Apples to oranges.

Most of your complaining is about the price. Sorry for you but just like the Sony RX there's no equivalent at any price.

Why didn't you use the 01 Prime for this test?

3 upvotes

We did shoot a test series with the 01 Prime. Because it's a much wider-angle lens than we usually use, we have to shoot it closer to the scene.

At the working distance of the 01 Prime, the centre is sharper but the performance then drops-off badly (probably as a result of curvature of field). The results look considerably worse than these.

This is one of the problems our forthcoming test scene is designed to resolve and the Q7 will be one of the first cameras to be included in the new scene, which we will publish as soon as the new interface is ready.

Pentax needs to update the kit zoom for the Q. The 02 has never quite been up to snuff and this result further illustrates that unfortunate fact. The 01 and 06 are pretty great, but every ILC needs a good standard zoom. C'mon, Pentax.

From what I've seen the IQ is pretty similar between the 01 prime and the 02 zoom. Maybe they have a bad copy? I didn't pixel peep these FWIW.

@zos xavius-
I find the 01 Prime to be sharper in general that the 02 Zoom, as long as you don't stop down past 3.2 or so. Refraction comes on quick with the original Q sensor, and that's partly why the 02 Zoom suffers at the long end. It's much better at the wide end.

0 upvotes

Entire scene looks out of focus, or has poor resolution. The difference with camera's with the same sensor zx-2 mx-1 is just too big. What lens was used? the 5-15 or the 8.5 prime?

Focal length is 14.70mm (68mm 35mm equivalent), so it must to be the kit zoom.

That would explain it because the zoom sucks at the long end

If the zoom lens is poor, doesn't that question the whole value proposition behind the Q7?

@Jim in Hudson wrote:
"doesn't that question the whole value proposition behind the Q7?"

If the 5-15 is not a stellar lens, it wouldn't be the first kit zoom to be a mediocre performer. That said, it looks like the copy DPR has may be de-centered so it's not clear that ALL 5-15 lenses will have the same issues at the edges of the frame.

But on most crop sensor mirrorless cameras like m43, NEX, Fuji X, it's really the large aperture primes that are the better performers. On my Nikon V1, I keep the 18.5 f/1.8 mounted 95% of the time. It's such a good lens, I hardly ever use the kit lens.

If I had the Q7, I'd keep the 8.5 f/1.9 mounted most of the time. Better IQ, better DOF control, and a smaller casing that balances better on the tiny Q7 body. So no, I don't think one mediocre kit lens means anything regarding the value proposition of the Q7 system. Besides, Pentax will surely release some more lenses.

0 upvotes

@marike6 - The problem is that currently there is no alternative higher quality standard zoom. For other formats these are available or announced, so you're not stuck with the kit one.

I too would keep a better prime on it most of the time, but I read it's only been released as a kit with the zoom, and based on this I really wouldn't want to feel I'm spending any money on this zoom.

0 upvotes

The zoom is pretty ok until about 10mm. After that it degrades. The long zoom 15-45 is excellent though. Pentax should really improve the 5-15.

0 upvotes

The prime performed very inconsistently when we tried using it (at the relatively close focus distances required for this test). We repeatedly re-shot the zoom to try to get the best performance out of it.

We will include the Q7 at the launch of our new test scene, which should allow us to use the prime.

1 upvote

The lens is not a very good copy. The left side is sharper than the right, looking at the two chess-lika squares to the left and right side of the top and also the silver-watch in the right lower corner is not very sharp either.
http://www.dpreview.com/reviews_data/pentax_q7/boxshot/imgp7101.jpg

You might be right. I thought the weak borders were a result of the Q lenses not quite covering the larger image circle of the Q7, but the watch, Kodak Q-60 Color Target, checkerboard on the right are much softer than the left side (Martini bottle, checkerboard, etc).

The Q7 lens seems to be de-centered so DPR should probably test another copy or better yet, use the 8.5 f/1.9 for these tests.

DPR uses the better 50 f/1.4 lenses for most DSLR test shots, why not use the better 8.5 f/1.9 for the Q7 studio test shots?

0 upvotes

@marike6 - I agree. I've gotten so used to DPR testing with excellent lenses I assumed it was standard practice and was surprised to see these poor results. I guess it could be a simple case that they don't have a better lens for Q7.

0 upvotes

The 8.5mm F1.9 01 Prime does not perform well at the working distances required for this test - it's sharper at the centre but terrible towards the edges (probably as a result of curvature of field).

As a result we had no option but to use the zoom, which gave us a softer but more consistent result.

0 upvotes

@R Butler

Maybe the Q lenses are poor at the edges, not only because of field curvature, but because they were designed to cover the 1/2.3" sensor of the original Q and not the Q7.

Something is blatantly wrong with these test shots. Do a comparison to the Pentax MX-1 (same sensor and processing engine) and the difference is night and day. In fact, the MX-1 shots look as good if not better than the P7700 shots.

To really check IQ, there is one missing think, where the focus is made and the distance between camera and scène. The Q with the prime do it's best at f2.8/f4. The AF is fast but sometime not very precise, you focus on one think, everything ok on live view, but when you take the picture and check the result, focus have change. When i want precise focus, i use the very handy focus peaking with 2x zoom.

I think DPR should place a sort of target in the studio scene where all the cameras tested need to focus.
This way will be no misunderstanding about front or rear focus and all the samples could be compared precisely.

AF not precise enough with contrast AF and very large DoF?

That's concerning to say the least...

I have used different cameras with contrast AF and various sensor size (NX10 & 1000, Fuji X10) and I always had very precise AF albeit somewhat slower than phase-difference AF...

If there was anything wrong with the tests shots, I'd bet on sub-par kit lens or pre-release bug in firmware but please, don't tell me that this kind of AF errors is something normal on the Q.

AF miss-focus is not common, from my experience, i encountered it in close focus, like the flower above. Even the smallest AF zone is big in those conditions. There is also not a very large DoF. In the first shot, the brown thing in the middle is about 5mm and DOF around 2cm.
AF do it's job perflectly well with the belt, fast, precise and silent through the glass.

0 upvotes

Those test results are too blatantly soft. They're wildly at odds with my experience using two original Q bodies and the 02 zoom as well as an 01 prime. I wonder if Dpreview got hold of a pre-production Q7 or 02 zoom with a defect, or maybe failed to turn IS off before making tripod-mounted shots. Maybe there's a bug in the processing engine.

I don't know what the problem is, but it's clear to me something's not right with the Q7 and/or lens tested, or with the way the test shots were made. I don't see Pentax knowingly bringing a $500 to $700 camera to market with such a pronounced and obvious lack of sharpness.

What I see in the ISO 200 new image of mannequin scene is comparable sharpness in the Q and G15 images.

What I also see is both those cameras delivering excellent sharpness, while the Q7 in Dpreview's test delivered unacceeptably poor sharpness. By the way, I noticed no such lack of sharpness in the sample photo series published a few days ago here on Dpreview.

Like I said, something's not right with the test Q7, its lens, processing engine or the way the test was executed.

OK, I went back and compared the still lifes. The G15 is noticeably sharper at the edge than the Q when viewed at maximum online enlargement. At the center, I find the G15 very slightly sharper, but the difference is negligible. And that is at maximum online enlargement.

Q is a system camera, which can instantly switch its modus operandi and take all new perspectives on photography depending on lenses and converters used. In fact it is unique and incomparable. To say it looks like the G15, P7700 or XZ-something, is true to the same degree as to say that you look like Albert Einstein.

Yes, people compare the Q to the other compact all the time. You can do it of course, just like you can compare the RX100 and the D800, for fun. But they are completely different tools.

A G15 or MX-1 maybe all that someone needs but the Q is more versatile and is more DSLR-like in its handling (manual zoom, yeah!). My hope is a true rectilinear UWA (12-24mm) that would make the Q truly unmatched by other compacts.

The G15 is f/4.5 1/60s ISO 100 but the Q7 is f/4.5 1/25s ISO 100. How come?

1 upvote

Ah, more bottles and cards shots … using which lens for the Q? 01 lens? 02? 06?
What aperture? Was focus peaking used? Image stabilisation used or switched off?

All front focused theories aside, it does seem the Q7 is doing a tad noisier at high ISO than the other two options discussed. A bit surprised given how well both Q and K-5 do with the Sony sensors.

Yes, it looks like it's front focused.

You can pick up a new Pentax Q with an 01 lens on ebay for around $225. At that price, it makes a very fun camera. If you are willing to do some PP, the results are very pleasing.

I must admit that the images from the Q7 are somewhat disappointing. I have a lot of fun using the older Q. If I don't pixel-peep, I'm happy with the results.... far happier than I was with the smearing on the newer Sony compacts.

Yep, it's still a 1/1.7" sensor.

Looks about like a G15, only the G15 is cheaper and comes with a faster lens and a viewfinder.

People like to point out the nice 47mm f1.9 prime for the Q system, but the G15 is still f2 at 47mm equivalent (maybe f2.2, but I think it drops to that at 50mm equivalent) so there is really no advantage there.

If you were interested in more zoom, the P7700 has 200mm reach, which is about what the Q telephoto would have with this larger sensor Q. It's still got f2.5-ish aperture at 50mm, too.

Still having a rough time figuring out why someone would want to spend $1000 for a Q and a lens kit when you could spend $450 on a G15 or a P7700 and get more in a smaller body for half price.

6 upvotes

Not sure where you're getting $1000 dollars from... I would be wondering why someone would spend that much as well seeing as the camera + zoom is $499.

That said, Pentax's own MX-1 has a excellent fast lens on it and for $399, might be a better option for certain people and is definitely better than the Canon and Nikon cameras mentioned (at least in my experience.)

0 upvotes

$1000
Q7 + kit zoom = $500
telephoto = $300
Standard prime = $200-ish

You'd need at least two out of the three to match the capability of the G15 or P7700. Probably all 3.

3 upvotes

Except that the 06 telephoto of the Q is constant F2.8, that I see you conveniently ignore. This means less ISO at the long tele photo and better DOF control than the P7700.

You say there's no advantage vs the G15, but you do mention right there that the Q lens is faster anyway, so there seems to be an advantage after all.

Of course, you also have other options like a very cheap fish eye which none of the other cameras give you, custom F1.2 prime for the Q mount which none of the other options give you, or ability to use other lenses which none of the other options give you.

And still smaller than those other two you mention.

So when you say "You'd need at least two out of the three to match the capability of the G15 or P7700. Probably all 3." you are really telling a half truth, as the other cameras cannot match either what the Q is giving you in that set.

It's pros and cons. Oh, you also forgot the current Q auto focuses *much* faster than either of the other two options.

Lol! $1000? Get a Q7 w/ the 01 prime and it is better anyday vs the G15 and the P7700, get a cheap Fotodiox K to Q adapter and a SMC-A 50mm f2 and you have a 250mm f2 equivalent for far far less

Q is a system camera, you know. There's nothing that compares to it right now, nor will (most likely) ever be.

how is the q7 with the 01 prime better than the G15? f1.9 vs f2 at 47mm is better? And you give up all your zoom range for that tiny 1/6 of a stop?

Nothing compares to the Q because nothing wants to. When you can give the capabilities of the whole system in a fixed zoom, why bother?

"how is the q7 with the 01 prime better than the G15? f1.9 vs f2 at 47mm is better? And you give up all your zoom range for that tiny 1/6 of a stop?"
Er. you are saying right up there it's a faster lens on the Q, and you are not even sure if the Canon is F2.2 anyway. You brought that up, not me.

You then, again, conveniently ignore some characteristics and facts- like what I pointed out to you on the zoom 06 lens which is a constant F2.8. Of course the G15 can't even do that.
Did I say the Q7 was unequivocally better? No. I said pros and cons. Hardly the "slam dunk Q7 loses to both" you made it out to be.

As for flexibility, again- pros and cons and depends what photography you do. It's far easier to zoom in on a Q lens than on the other options (it's manual). You don't get the DOF control of the 06 in neither G15 nor P7700, which can make for good portraits, but you ignore that. It's not as simple as you say at all.

2 upvotes

Of course, if you don't do much photography, then all these differences may get lost on you (note: I am not saying the Q7 is unequivocally better or even better- just pros and cons and a good camera in its own right). Which camera is the best match depends on your needs and wants as a photographer (if you at least try to do photography that is), and we are all different.

It may be a system camera and fun to shoot but maybe a small sensor system camera isn't a great idea. Switching lenses to give me less of what the G15, LX7 and especially RX100 doesn't seem like it is worth it. The original Q with an even smaller sensor may have been fun to play with but it was toy like.

I'd feel silly changing a lens on a Canon S110. May as well move up to the next class camera.

2 upvotes

@mcshan - apaprently like the other poster, it got lost on you the other things the system gives you that the other cameras are not. You say "switching lenses to give me less of what the G15/LX7... " - no, it doesn't give you less, it can give you more. Much more. You have a 200mm equivalent lens that is F2.8. How fast is that Canon at telephoto and is it 200mm? Which of the two cameras will give you shallower DOF for a portrait?

Why are you missing this?

1 upvote

Two things: there appears to be a bit of front focus to the Q7 shots. And the raw file links are broken.

2 upvotes

The truth is they are all very close, with the P310 slightly below par. They are all much better than 1/2.3" sensored cams and much below apsc.

0 upvotes

I was wondering how the Q lenses would do on the Q7. The kit zoom DPR used doesn't stack up well against the P7700 and G15. The borders and corners (and the center really) are just not as crisp as the Nikon and Canon in the RAW files.

High ISO looks great (exactly like the MX-1), but images are a bit softer than the other 1/1.7" cameras.

The 8.5 f/1.9 should do considerably better. I'm just wondering if it's the Q lenses designed for a smaller image circle or if the kit zoom is just not such a good lens.

2 upvotes

Agreed, the zoom isn't pulling its weight here. I purchased my Q as a kit with the 02 zoom and recently acquired the 01 prime and the difference is unmistakable.

1 upvote

I own Q lenses 1-6 and I've always been a bit disappointed with the standard zoom. The standard prime and the telephoto zoom are much better, in my experience. I was hoping they might have made a mark II version... maybe with constant f2.8 like the telephoto... but at least one with slightly improved optics.

True, it is the softest of the group even in Raw.

...it's front focused. Look at marks on the paper in the foreground. It's subtle, since DOF is so big with these cameras, but it's there. Dunno if this is an issue of the testing or the camera misfocusing, but that's definitely the issue. Do over!

Many of us are surprised Pentax is still chasing this dead end.

4 upvotes

If an ILC with a 1/1.7" sensor is a dead end, aren't the less versatile fixed-lens compacts with the same sensor size also dead ends? And yet they seem to be quite popular.

The problem is that people think of the Q cameras as competitors to the mirrorless ILCs with larger sensors, rather than as enthusiast compacts with the added bonus of interchangeable lenses.

2 upvotes

@tkblsc- as said in the announcement, the Q system is actually indeed- a best seller no less, in Japan. How is that exactly a dead end? Just because the camera is of no use to you doesn't mean it's bad.

@Revenant- I think the real problem is that people who are so obfuscated by sensor size and other limitations without seeing the pros just aren't photographers. I see a lot of advantages to the Q system for street life.

Pentax should really hire a good industrial designer.

Their cameras are good and perform well.

But they appear just freakishly ugly and out of fashion.

I disagree. I find the Q7 to be quite an attractive camera.

12 upvotes

A camera is not a fashion item, but there is nothing ugly about the Q7, MX-1, K30 and one of the nicest looking DSLRs ever made, the K5.

But aesthetics are subjective.

The great thing about Pentax is they are not afraid to take risks design wise. As someone who hates conservative designs, the same thing over and over again, I really respect that.

So just which cameras do you consider good looking and fashionable?

just wondering how a CDAF system can front focus?

In reality, the Q is quite a cute camera, well designed and build, and the grip is good. And for fashion, ou can choose colors for body and top, it's unique. Sadly, lenses comes only in silver ;)
And more important, with the prime, IQ is great
