On a recent shoot the battery gave out prematurely on the K20D (shooting RAW + JPEG perhaps?) and I resorted to the DS. Now here are two pictures, one from each camera. The DA 50-200 at f11 was used and the ISO is 200, shutter speed is 180 and the lighting is pretty similar. PP is identical and minimal. Can you guess which is which? I've removed the EXIF data

Both very good. i would say 2 is from the DS. Either way, it makes you wonder why you need anything more sometimes.

This is difficult because the images are different and the resolution on screen is limited, but I'm going to agree with smc.

The first from the K20D and the second from the *istDS. Both are excellent anyway, as pointed out.
Best regards, John

Another one for the 1-K20D and 2-DS.

They are very similar, which is not surprising. If you take an average of many pictures it might be more evident, but clearly and as time progressess, its going to be particular aspects of IQ, like extreme low noise or features like HDR and fps that are going to make people move to a new camera.

I would agree.

The fact is both cameras have performed superbly well as beautifully crafted tools. And also the photographer has used them to perfection as a top class artist/craftsman does. The closeness of the image quality suggests to me that the desire to pack more and more pixels into a camera body is probably more to do with marketing than with achieving ultimate photographic excellence.

On the face of these images David, but if we were making A3 exhibition prints then the difference would be very obvious.

I'm still not saying which is which and I take John's point about A3 prints, when fully zoomed in on screen the K20 image is 'smoother'. However, these are destined to be actor's 10x8 headshots and printed at 10X8, or indeed printed in 'Spotlight', at which size they still can't be told apart.

I think when all else is equal, you get sharper (though lower resolution) pictures from the DS. Picture 1 is sharper, so the DS gets my vote for that.

I'd say picture 1 was taken with the Ds.

I miss my Ds and sometimes tbh regret the "upgrade" to the K20D.

I use a DS (and a K100DSuper). Regrettably no experience of the K20.

I find the DS output excellent for my needs, which don't include A3 prints! Any problems are usually user error, not a shortcoming of the camera.

I think no 1 is from the DS.

I've gone 1-K20, 2-DS

My reasoning is that I find my K10 resolves extremely fine features such as hair rather better than my *istDL2 does. The DL2 packs the same sensor as the DS, and picture 2 looks as I would expect output from my DL2 to look.

Both look really good though, and as said above I very much doubt you'd notice the difference up to ~10x8 unless you were really looking for it.
you don't have to be mad to post here



but it does help

I don't care to hazzard a guess, but will add this:
My ds2 gets plenty of use in the studio.... despite owning 2 k10's...
Fired many shots. Didn't kill anything.

I've had A3 prints done from some of my DS images, sometimes heavily cropped images, and they still hold their own in club competitions and exhibitions.

Ken your examples show some very good examples of quality from Pentax DSLRs. I would guess that No1 was the isDS 6mp camera.

I too have printed A3 from my isDL2 and was amazed at the quality. I confined my Canon 5D full frame camera to back-up on the results of my isDL2 tests.

However the Pentax K20 is superb at high ISO low light performance. I am amazed at its quality in low light.
Friendly Regards
Graham
