Just out of interest David was the noise Jpeg or RAW derived or did they even say?

Nice set, my preference is number one but I also like number four (even more if the sun had disappeared a bit :wink.

Mike, I can assure you that although the framing appears good, it was mainly down to the fact my knees were getting sore Number two is good but I like the tighter crop on the cafeteria handle with three as it gives the picture greater symmetry

Nice pics Huw, I like number 3 the best
Thanks Mike, I thought you would appreciate the composition Nice pics Huw, I like number 3 the best
Number two is my favourite

Having posted those images yesterday I thought I would run a quick experiment to verify what the K-7 is capable of (SR and ISO) and to check that the previous images were not a fluke.
I set to shutter priority 1/5 sec with ISO set to 3200, generally settings I wouldn't use
I then took two groups of two shots in each case one of the group had the shake reduction turned off. I deliberately made my shooting position less than ideal by kneeling on the floor (Both knees).
These are all RAW PEF PP by CaptureOne 5 Pro with a little additional noise reduction and resize in Helicon Filter Pro. All Exif data is retained if you want to gander.
Image one shake reduction on

Image two shake reduction off

Image four shake reduction on

So if you are considering a K-7 I would say despite what others (magazine articles and alike) might have you believe the K-7 is by no means bad at high ISO in fact I think it's pretty good.
Like wise shake reduction works very well indeed

I agree with Stefan, I much prefer the low key approach. Nice set of images

Hi Mike, not quite true i'm afraid, i sell the 7D and have tested it, its ability a high iso (above 800) is a mile ahead of the k7. The K7 and the kx are let down also by the poor inbuilt stabilisation, it's next to useless, but i still bought the k7 !!!

Interesting Dave, I find the K-7 Pentax Shake Reduction to be excellent.

As least as good as Olympus which I think is pretty near the top of the tree.
Example, hand held 1/5 second, sharp as a nail. Or maybe it's next to useless??

With regard to noise again I'm not sure what all the fuss is about.
If you get the exposure close it's not an issue. Example ISO 3200 shot in the rain btw

Edit: I should add both shots were RAW PEF processed using CaptureOne 5 Pro.

Interesting story Mike, glad the lens has found his way back to the camera.
The lens is very well made but like Huw says it isn't stellar in terms of IQ, which is a real shame
I don't have the lens but it seems the wide end of it isn't super right?
I would also love to see the non HDR.
Actually Stefan it's fine (well my example is :wink provided you stop down a little, anywhere from 16 to 50mm. Perhaps I paint too gloomy a picture Interesting story Mike, glad the lens has found his way back to the camera.

When at it's optimum I believe it has outstanding resolution. Centre sharpness even wide open is very good. The review on Photozone very accurately summaries the performance I have found with the lens.

I would be interested to know if they were able to show any evidence of shortcomings in terms of image quality, particularly with RAW files.Unfortunately with the tough competition from Nikon and Canon the K7 can't live with the performance and image quality benchmarks laid down by the market leaders.

Be interested to see the non HDR versions
Noticed you were using spot metering, did you have to adjust the exposure much in conversion (of the non HDR ones)?
To be fair I've always been a little underwhelmed by my 16-50 but not because it's particularly bad because it isn't. Unfortunately I had been thoroughly spoilt by the Oly ED 12-60 SWD from previous system
Occasionally my 16-50 will miss focus, luckily not too often. At the right combination aperture and focus length it can produce an image that positively surprises (in a good way). So now that I've accepted it's short comings (that you can quite easily work around) I'd say its a definite keeper. Having said all that if bargain 17-70 comes up I might consider a dabble
