On article Pentax K-70 added to studio test scene (18 comments in total)
In reply to:

pacnwhobbyist: When compared to the T6i and D5500, the jpeg NR by default is pretty-heavy handed in the Pentax and buffs away a lot of the fine detail at ISO1600. The Nikon also has pretty strong NR but not as much as the Pentax. It doesn't necessarily mean that the Canon is the best overall, but they do the best job and retaining detail at higher ISOs in JPEGs, I think.

RAW on the other hand, both the Pentax and the Nikon beat the Canon, although it's not evident unless you examine it closely (and not by a huge margin). In fact the Pentax and the Nikon look almost identical which is not surprising since they probably share the same Sony 24MP APS-C sensor.

Honestly, any of these cameras are capable of turning out excellent images despite some minor quirks for image processing. You would just have to turn the NR down on the Pentax as one of the first things you do.

It's the sharpening which is much weaker - Pentax has different types of sharpening, and the amount can also be set; but the default is nowhere near as extreme as for the Canon.

Thank you, DPReview. Real life and studio samples, it seems you're really paying attention to Pentax ;-)

I'm noticing, however, extreme sharpening differences in JPEG - the Pentax has little applied, while the Canon T6i has tons of it. Default settings, I presume?
Perhaps its time to find reasonable settings on the tested cameras?

Favorable Exponynt: On Battery life. Pentax has a comparable battery to Nikon. 1860Mah 7.2 volts and 1900Mah 7 volts. They both use the same fujitsu/socionext processors and sony sensors. Yet Nikon has a much better battery life. How so? Does Nikon have a volkswagen trick to fool the CIPA test, or would it be the built in shake reduction Pentax has? Maybe a CIPA test should be done with SR off and see whether that makes a difference.

Yes, GPS is off by default (there's a dedicated button on the pentaprism housing).

The SR system, however, will be active even when Off - when it won't do anything else but to hold the sensor in place. I'm not sure how much it affects the battery life, though.

By the way, I'm not sure Pentax is using the same Milbeaut processors as Nikon; perhaps due to lower volumes Pentax is going with a more off-the-shelf version while Nikon is customizing more? And there are other components which can influence the battery life.

In any case, while not great I'd say the battery life is very much decent. It's not a sports camera, you're not going burst after burst at 10+fps with little pause.
It is of course an area Pentax engineers should improve, but IMO it's not critical.

K1000usr: I have one suggestion for DPR. The anti-vibration (5 axis image-stabilization) in K-1 really works very well. It works with all lenses: old or new. This is incredibly powerful, and very obvious advantage. I can easily take very good shots handheld at 1/10 second.

Image stabilization mode of K-1 has not gotten so much recognition in this review as it should have. Perhaps image stabilization should be a category for evaluating all cameras.

The dollar cost saving in body-based image-stabilization is substantial -- Not to forget, the lens also becomes lighter.

That's nitpicking.

Yes, I know that - it's standard practice for interchangeable lenses with optical stabilization. Pentax does that too (for the 645 - in-lens SR).
What I'm saying is that with Pentax K (in-body SR) and especially the K-1, the SR On/Off setting is much more easily accessible than digging through the menus.

We don't have "an easy switch on a lens", but the SR setting is not in a hidden menu, either. You can have it on the easily accessible Info menu, it's automatically deactivated in certain situations (e.g. with the timer) and you also have the new Smart Function dials.

rjmcsr: Why the compare mode doesn't allow to pick the Nikon D810?
Also "The K-1 also offers some of best dynamic range on the market (falling just short of the Nikon D810 at base ISO)" maybe because the lower ISO of the K1 is 100 the we can say that K1 dynamic range is above the D810 for ISO higher than 51200... "Image Quality is where the K-1 definitely outshines the majority of its competition at this price point, with the camera giving one of the best Raw dynamic range results we've ever seen, falling just short of the industry-leading Nikon D810" apparently this is arguable...

http://www.photonstophotos.net/Charts/PDR_Shadow.htm
http://www.photonstophotos.net/Charts/RN_e.htm

So for image quality comparison, conclude for yourself...facts are facts words are words. Then a 1% makes difference between a silver and a gold award camera for when browsing in DPR. Regards

Indeed, the in-body SR is one of the main points of the K-1 (and what makes possible special functions like the Astrotracer or Pixel Shift Resolution).

Though lenses are not always lighter, see the D FA* 70-200 f/2.8 ;)

ondrejbobek: Where is the button "i want it"? :)

SimenO1, I like how you're thinking.
Though I'd also keep a Canon kit, just in case I'd be shooting swerving cyclists...

miles green: @dpreview
In the conclusions you state "Another point of frustration was the fact that the focus points aren't illuminated in the viewfinder until focus is confirmed, which makes it hard to even find your AF point to know where to place it in low light conditions. "
If you press the focus mode button (on the side of the body) while you are shooting, all the active AF points light up (1, 9, 25 or 33 depending on your settings). I think this is the feature you were missing?

The K-1 is the first (and so far only) Pentax with a LCD overlay. Yes, it works differently from any of the previous models.
It's not a big issue, but the criticism is valid.

Alex Sarbu: Getting back to a (now) confirmed issue:

"Another point of frustration was the fact that the focus points aren't illuminated in the viewfinder until focus is confirmed, which makes it hard to even find your AF point to know where to place it in low light conditions"

I believe this could be fixed in firmware, and that such a fix would make for a nicer shooting experience in low light. There are several other Pentaxians thinking the same, on the Pentax SLR Talk forum.

I think this behavior (having the AF lights to indicate selected/active AF points, and not focus confirmation) is better than the current one. I think it's fine having only the classic hexagon and the camera beep to indicate focus lock (some other things might be done, e.g. red AF lights blinking slowly if focus can't be locked).

DPReview, was this explicitly communicated to Ricoh? If not, could you please do it, I'm assuming you're in contact with them?
Thank you.

Because that's what it is. You can argue about its severity, priority but not this.

Since you can shoot with the AF mode button pressed down (though you can't change AF points or exposure parameters), it's not a big deal. But it's up to Ricoh Imaging to accept/reject this small enhancement request, and to prioritize it.

You are mistaken, Ricoh Imaging/Pentax is listening. One obvious example is the lockable mode dial - when they listened to both those saying it should be lockable, and to those saying it shouldn't. ;-)
And even if they wouldn't change anything for the K-1, it's something to consider for a future model.

In any case, I can be happy with the camera either way. I'd be slightly happier if they do it (as a configuration option seems the right solution) ;-)

It's not a non-issue, but an usability issue.

I think Ricoh Imaging would be interested in such feedback.

In reply to:

GrayW: Hmm... it seems that AF-C on a static tripod with the subject weaving in and out of the focus field isn't a very good test of the K-1 real world AF capabilities.

AF-C with Expanded Area AF will attempt subject tracking. This is how you did the swerving test I was talking about, right? (unless the EXIF is lying me)

What I'm saying is that you should've started by giving the central (selected) AF point a clear target, e.g the cyclist's face. I'd say that IRL you would actually attempt that.
If you're testing the camera's ability to track the subject across the part of the frame covered by AF points (!), then obviously you shouldn't keep the center point on the initial target. IRL you might attempt to follow the subject, though.

Note that I'm not calling you incompetent.
Also, keep in mind that your tests are (unfortunately) inconsistent and not an industry standard. It's fine if other people are proving the K-1 works, even if they don't replicate 100% what you did for the K-1.

odpisan: Great!

I am very haapy & proud (NO joke) to be "Penax fan-boy"!

I just do not understand others who are insulted with this new original name of our community.

:o)

Fuji X-Pro2 .... 2480
Sony A7R II .... 2159
Sony A6300 ... 2128

Pentax K1 .... 2511 & rising .. record is broken! But I lost my bet .. too late fo 1 day.
:o(

"Fanboy" has a very strong pejorative connotation. It is an insult.

Simply preferring a brand, choosing a brand, being reasonably happy with a brand doesn't make one a "fanboy". It makes you an user.

In reply to:

Alex Sarbu: By the way... since I'm criticizing the AF tests, AF tests criticism (when not valid) and who knows what else; it's not like I don't have positive things to say.

My impression of the review is not entirely negative, far from it. Yes, there were issues (e.g. the defective 77mm samples, the Pixel Shift not being supported by Adobe etc.). However, when everything was put together, as I read it I kept saying to myself, "hey, nice from them they're mentioning that".
The authors - this was my impression - were really into reviewing the camera, discovering what works and what doesn't, this and that. Should I say, enthusiasm?

I'm also impressed how Pentaxians immediately started putting the K-1 to work, especially in areas where it should be weaker (see the Pentax SLR Talk Forums). Tracking swallows, really?

Last but not least, I'm impressed by the camera itself. No product is perfect, but the K-1 is a sound product.

And for Pete's sake, putting the camera in AUTO will force AF-S, effectively disabling AF tracking!

ervinberxolli: I have a Canon mark 2 and i was very happy with the camera but is an old camera and i want to upgrade to a new one. The Canon 5ds is to expensive and i dont like the colours and the dynamic range. Looking for other cameras i saw Pentax K1 and reading all the reviews that are on the internet about Pentax K1. Im thinking to give a try and change my gear to Pentax. The price is affordable and very good quality images. I shoot a lot of weddings and i want to know something more how pentax works with the flash if it is possible? AF is good enough for my kind of work also the 15- 30 mm, 24-70mm, and 70-200mm are good Lenses and cover 95 % of my work.

That was funny!

By the way, Metz should launch some firmware updates for the K-1, shortly.

In reply to:

Rychok: I do not really understand chosen settings for this focus test.
In my opinion none of them is suitable for tracking. Select 33 - based on manual is single point ficus chosen by user, and you will have to follow the subject, The same is center with difference of selecting center point only. The settings for tracking are called Expanded area AF with three options S,M,L, Small (Sel S) 9 points, medium (Sel M) 24 points and large (Sel L) 33 points.
So off course the results are pretty bad for SEL33. The problem for me is that whoever was testing the camera did not read or understood manual of camera.
Of course I could be wrong about proper settings for tracking, but they works me.

Sorry, but did you had a clearly defined target under the selected (central) point, in your swerving test?

Note that I'm not expecting the Pentax subject tracking to perform particularly well. I haven't really tested it (IRL and so on), but it does seems prone to lose the subject.
However, can it perform at all if it doesn't even have a proper subject to begin with?

Don't cry so much. You entered this by saying ""Pentax fanboys") . ' It's called calling a spade, a spade, not name calling". I suppose that's your "neutral observer" position, since you're behaving like this for how many years? Insults? Lies? Insults, again?
But it's fine, after all, you agree with DPReview's stuff (for now).

Repeating a broken test one thousand times won't get you valid results. Just like watching some silly Flickr statistics won't give you market share data.
