On article What is equivalence and why should I care? (2501 comments in total)

/// "ISO and its role in clarifying and confusing
This means that, a Four Thirds camera with a 50mm f/2 lens at ISO100 should produce a JPEG of the same brightness as a Full frame camera with a 100mm f/2 lens at ISO100 and, set to the same F-number and shutter speed, even though its smaller sensor means it is receiving 1/4 as much total light."///

No its not ! A camera with lens - regardless of focal length - at F2 and ISO 100 will have the same shutter speed be it FF or M4/3's, and produce a similarly bright JPEG. Total light ? You're just confusing the issue ! Was this article written by Tony Northrup ?

Even a FF lens is over projecting and has a larger image circle to keep, therefore a FF camera doesn't capture "Total Light" projected by the lens - you see how stupid my point is ? THERE IS NO SUCH THING AS TOTAL LIGHT. A lens is just projecting an image over a sensor. DPR is talking about curtains, the more I open my curtains more "Total Light" will enter.

The problem here is that the rear 1/4 of the external barrel of sigma lens have remained the same for some time. Back in the day, sigma made that final 1/4 of the ext barrel narrower for nikon and pentax. Now its all fat to suit EF mount. Its cheaper for Sigma to make fat in the back lenses for EF, and make the K-mount and F-mount with a much larger diameter. See the difference with the Sigma 400mm 5.6 telemacro and the EF version HSM.

Kendunn: Thank goodness it looks like the dark age of digital is behind us and everyone is moving to FF. Lets not kid ourselves, the ONLY REASON the early cameras weren't FF is cost. There was no real size advantage to speak of and DOF was as much as a con as it was a pro. M4/3 is way smaller than APS with on par IQ. I never liked APS, had a couple but moved to FF and never looked back. I do have Olympus M4/3 for fast and light, which I love, and keep FF for when I need fast focus or DOF control. Again, kudos to Pentax, it wouldn't take much to get me to buy into their system even if it means starting over, but either way, my next Canon or Nikon (I currently have both FF systems) will be cheaper because of this camera! Only thing this day and time it might have made sense to come out with a mirrorless FF like Sony, but that would have meant new lenses.

Ya got old film photographers saying they can make the same size prints with apsc that they made with medium format film.
Micro 4/3's is the new 35mm
apsc is the new medium format
FF is the new 6x9
Medium format the new large format.
I think you have a little tunnel vision, "Fuji has justified their format". Man, you live under a rock. Last year, I could have bought FF, I bought an apsc lens instead. Apsc ISO today is FF ISO of 5 years ago, thats 5D markii vintage. The problem is that apsc is still very competitive to FF in more ways then you care give it credit, and thats why FF is losing against apsc. APSC is bigger than FF .......why ? Because its better. For a fraction of the cost you can get similar results. "What other purpose than cost saving" M4/3 is a mount shared by olympus and panasonic - its the new 35mm. You're definitely a canikon guy - you just can't see the trees for the Forrest.

dansclic: Magnéto shot,
Why should Pentax apologize ? are you serious ?
if I havé a BMW, SHOULD I complain because Dunlop does not make perfectly dedicated tyres ?
I do,not understand why so many people complain and are using sigma lenses : use Pentax lenses. Or maybe you do not trust pentax lenses. Then, buy canon or nikon, they have better lenses.
Getting sigma's or any samyang will cause you problems , at least software problems. I never mount non original lenses and you cannot blame a manufacturer for not being compatible with secundary lenses.

Pentax might in future just leave a little notch in. I got one of those lenses on the list so I'll be getting Sigma to fix it.
I don't know where you get "canon or nikon, they have better lenses". I got K-3, Pentax apsc lens range is better than canikon apsc lens range .... oh wait, canikon hardly have an apsc lens range, and you've gotta go with sigma or tamron. Thats why I switched from Nikon. Pentax has an exquisite lens range !

Jon Ragnarsson: If this was a Canon or Nikon, people would be going crazy over it. Such an underrated cameras.

I think its a bit silly to criticize Pentax for not having obscure big dollar lenses which canon and nikon sell only a couple of hundred of per year. Pentax isl creating a new FF lens lineup, the basic zoom pro lenses is what we'll get for the time being. Should be enough to keep the enthusiasts and pro's happy for the time being. the Primes will come later, thats dependent on how well the K-1 sells. Its gonna be a small ecosystem at the start. The APSC ecosystem was very good. People in Pentax land love 2 shoot the Limited's, and travel light. You can't be everything to everybody, and Nikon and canon isn't what I'm looking for, therefore not for everybody. I look at the Fuji line up, and some pro's love it, its not for everybody, the canikon drum beaters will say look at the range of lenses canikon has, REALLY? do you own them all? Most pro's don't need all that gear they horde and can probably make do with less. Noone actually needs a 200mm f2 c'mon, make do with less.

Whats with all the apsc hate? Ever heard of the D500 and 7Dmark ii and Fujifilm.
There's nothing wrong with APSC, stop complaining. Its a format in its own right. Full frame is not the be all and end all of photography.

In reply to:

Astroguy40: Hi i have had a look at the comments here and can anyone tell me if i am better off for getting the Pentax or the Nikon d810A for astrophotography and video?
I have heard with the nikon there's no way you can use it for normal landscape or wildlife photography as you will have a run of colours all over the picture but the pentax can be used for both so my concern with teh pentax is that as the sensor is not persificly made for astrophotography and is not rendered useless for any other type of photography and video says the picture quality will not be as awesome as the Nikon D810A heres the link for the D810A http://www.nikonusa.com/en/nikon-products/product/dslr-cameras/d810a.html

Conventional UV IR cut filter combined AA filter on the sensor blocks out UV IR from 390nm then stops IR at 700nm leaving the visible spectrum for camera to capture. 810A lets in visible red lower at 656nm, and will ruin normal images. You could get around this buy UV/IR cut filter on lenses above 30mm. Are you mounting camera with long lens to capture nebule? You must buy motorized equatorial mount for d810 and K-1 for long lenses. K-1 better with wide angle lenses no need for motorized equatorial mount, no star trails from sensor shift. If you want video for normal use then you would need the K-1. Its not in the sensor, its in the UV/IR/AA filter sitting on top the sensor.

In reply to:

Sandmanusd: So from this review it seems the auto focus on the lenses is the culprit on the Auto focus "problems" not the camera itself. Are there any other reviews out there that indicate that the Pentax Auto Focus is substantially slower than those on Nikon?

I am up in the air between this and the D7100 and really the ONLY thing throwing me for a loop and preventing me from buying the K-3 right now is the problematic slow auto focusing lenses available for the camera.

Is there any other reviews out there on the interwebs that can verify or refute the claims here that the slow AF on the lenses are to blame for the issues with the Cont. AF they see here?

This is a deal breaker for me really if this is true. I want fast auto focus lenses, like those available for the Nikon D7100... Any body with some thoughts or links to shed some light?

Anything thats screw drive (Bar macro) is just as fast as L-series. I've got 16-50 2.8, and its very fast- canikon fast. 50-135 2.8 is a bit slow because of the longer throw. 200mm 2.8 is a little slow but is ridiculously sharp. if you are shooting sports, the new 70-200 2.8 or Sigma model should do the job. (There could be others fast enough)

I've used some nikon gear, and some lenses are pretty slow with nikon too. So its lens dependant.

If you know which lenses you need, make a table of lenses from either brands, and find out how they rate by users.

At the end of the day you've got to check off your listed lenses on the table as suitable or unsuitable. Pentax has definitely got the sharpness. But SDM is not the same from lens to lens, and the SDM failures have apparently been sorted.

Tell people what you are shooting, and they can advise you better. Nikon people or Pentax people.

In reply to:

We PhotoBooth You: I still think Pentax are falling behind too much.

You need to understand that Pentax has largely been about the image quality. I switched to Pentax because the image quality was very accurate - Image quality first !

AF speed has been a little behind on some SDM lenses, but screw drive are just as fast as L-series.

Do I want the muted colors of a nikon, or dullness of a canon? Yeah I'll get slightly better AF, but I prefer that my Pentax colors can stand side by side next to a Foveon. Pentax image reproduction is far out in front.

Canon and nikon tune down their colors to lessen color noise, and get better DXO scores. DXO scores don't rate accuracy or use a reference camera like a Sigma foveon to benchmark accuracy. DXO is the most unprofessional.

pentax has the largest range of DX lenses.

A camera is not auto focus, a camera is about the image it captures.

In reply to:

jensenn22: I am thinking of trading in my Sony A7 mk2 for a Pentax K3 even though my Sony is much more expensive the Pentax K3 still seems better. Am I doing the right thing here???

I've got a K-3, but if I were already invested in the A7ii, I wouldn't trade in the A7ii for anything, I'd keep it. Then if the k-3 takes your fancy, by all means have it as a second camera.

Sony being the first 35mm mirrorless maker has the advantage of being WAY out in front with mirrorless. The disappointing thing is the FE lens range is small, and not too sharp. The A7ii images are excellent and really pop.

The dedicated lens range for Pentax crop is the largest, and you can put together a fantastic collection of lenses.

Get out there and enjoy your A7ii !

Zeisschen: Pentax is the only DSLR maker that manages to pack it's technology in a modern looking industrial design body. Canon is 10 years back, Nikon around 15-20 years...

If I went with a DSLR, for sure i'd be a Pentax

@Zeisschen. As per Pentax quality, you will get the better image quality as opposed to equivalent canon or nikon models.

I switched a while ago to Pentax for the image quality. With this model you'll also have Pentax's outstanding weather sealing, and the added features of Shake Reduction.

The only thing missing compared to the others is more auto focus points. But I'd rather have better image quality rather than extra auto focus points and the extremely disappointing image quality from the equivalent Canon and Nikon.

Its hard to beat Pentax colors and image processing ! Vastly superior images.

Peiasdf: Picture 3 brings up memory of a visit to the science & technology museum in Taiwan 20 some years ago. Not saying anything bad about the K-S2, just the lighting and the honeycomb pattern on the top panel reminds me of a simpler time. It made this ugly duckling of a camera more endearing to me. Maybe I will pick up an used one someday as souvenir. :D

Some folks like the plastic designs of Canon and Nikon Bodies. Some folks like the retro designs of Olympus and Fujifilm.

And some folks will like the modern styling of this K-S1.

All I know is Pentax has been colorizing for quite a while now, and when Nikon release a red d3200, or Canon in red or white, everyones like "Oh bravo, how cool"

Jonathan Lee: very nice and even lighting on the camera. esp, considering this is a on location shot. good job!

The light on the shutter button changes from green to red when switched between stills and video. The WIFI glows green when switched on.

Why do they illuminate ? To indicate they are on, or in a particular mode.

Kind of like when you open your car, and the ring around the ignition lights up, so's you can see better to insert the key. This works regardless of if its day or night.

Or like when you open your fridge, the light turns on so's you can see inside the fridge.

Some may see this as purposeful, and others may not.

ProfHankD: Well, it's nice to see I'm not the only one 3D printing camera prototypes... but this doesn't give me warm fuzzies about when we'll see the actual product. This reeks of being only a marketing test. Let's hope I'm wrong. ;-)

Ricoh did the same thing with two lenses at Photokina 2014. The lenses looked like they were 3D printed in part.

Those lenses have materialized before CP+ 2015, with D FA designations ...... meaning 35mm full frame ready. One is a 70-200 f/2.8, and thats a clear give away that the FF is coming.

Rutterbutter: Lets see what would we want...
- 36+ Megapixel
- 1/250th / sec flash sync or faster
- wifi
- focus peaking
- Dx lens compatibility
- Faster Focus speed and sensitivity
- 4K video/30+fps
- Touch screen with toggle to de-activate
- 7+FPS
- ISO Native 50-102400 or higher
- 100% viewfinder
- Weather sealed/magnesium body
- Digital focus crop. Like D7100 for maximizing focus coverage
- Better in camera HDR and live preview of filters
- No AA filter
- 1000 shot battery approx
- Swivel screen and articulating.

Feel free to add to this. but this would probably be the best selling camera ever..

@iudex: "There are no DX lenses for Pentax. DX is a name only Nikon uses for designation of APSC sensor (DX lenses = Nikon lenses for APSC). Pentax lenses for APSC sensor are called DA."

DX and FX are used as designations for crop and full frame lenses in the Tokina brand as well as Nikon. The Tokina 10-17, 12-24, 16-50, 50-135 were all co-designed with Pentax, and have DX designations, but in Pentax brand they have a DA designation.

In reply to:

Mattersburger: Reminiscent of the Pentax 67, no?

The hot tip is ...... is that its designed like that because it might use sensor shift to boost the resolution like in the Olympus OMD 5ii. The OMD 5ii boost its 16mp sensor up to 40mp with sensor shifting.

Will the Pentax 35mm do the same and bring medium format sized images to the market ? Perhaps the 67 styling is the give away !

If it does, it means sensor stabilization (or IBIS), is the winner in the debate over lens based stabilization versus sensor based stabilization.

Heie2: ahahahahahahaha recommend the D7100 over the K-3.

Ahahahahahahahahaha

4. Access to only a fraction of the lenses of the Nikon system, many lenses of which have such slow motors that they can't seem to Z-depth track during continuous AF quickly at all (something we showed in our K-3 review).
I have the K-3. I don't shoot sports ....... most people don't shoot sports. My AF speed is very fast and I'm very happy with it.
The Nikon lens range is irrelevant to a consumer like myself, I'm not going to spend $4000 + on a lens.
What I need are ultra compact high quality optics like Pentaxes Limited line. I don't need to lug around huge Nikon glass.

The fact of the matter is DPreview does not have a clue about the market. Ya'll think that every piece of equipment should be pitched to pro's shooting sports.

I woke up to this "sports-sports-sports" mantra. Pentax, Fujifilm and Leica are artistic brands for photography. In terms of image quality, the D7100 cannot touch the Pentax K-3. AND THATS WHAT ACTUALLY COUNTS !

as per your sample images i had seen for most of canon and nikon models 18-135 chosen.my requirement good colour contrast in picture,Backround blurr images and potrait.please suggest me the best.please mention the pros and cons.
iam waiting for 1200d review in dpr with sample images.

bharath1234, I think you're splitting hairs. Those are budget kit lenses and they're all right, but they're crappy next to high priced lenses.

Out of the "tourist lens" 18-135mm range, I think Sigmas 18-125mm was slightly sharper than anybody else.

Prime lenses are the best, they just take a little time getting used to.
