PP consisted of a light brush with Neat Image and a low radius sharpening after resizing (0.3 X 90) . That was it. Noise at 640 was really not bad.
Thank you. Not that bad at all.

They look great to me. Of course, I have never had issues with the K10D's image quality, I think it's great.
"Of course"?

Of course, to my understanding less than 50% wants to see anything. But if you are in a good mood you can make a try.

Very Nice

I have to commend you on your very fine images...Beautiful! Have you tried the 12-24 Pentax? I have it but haven't had the time to give it a real workout.

First of all, maybe there is a language barrier at work here. "Of course" in the context that I used it means that my experience with it has been fine, not that I thought it was incapable of error.

I have seen these posts before and they don't really change my opinion. These photos are exactly what I would expect from high ISO shots in low light from film or digital.

It was a small reward for a long cloudy fruitless day. I had a tripod with me but every time I tried to place it anywhere the security guards decended like jackals and told me to move on...so I cranked up the ISO and tried being covert....

The 12-24 is a good solid, workmanlike peice of glass. It has faults, like mild ca and some linear distortion, but neither are obtrusive compared to the 16-45. I have yet to try it in a studio but it could be a lot of fun. I think it beats the DA 14mm at the same focal length at F4 and also gives the DA 21 pancake a good run for its money with slightly less contrast but comparable sharpness stopped down. Corner sharpness is pretty good as well.

Great stuff, Steve, of all of them I'll have to take #2 as my favorite, very nice indeed.

Cheers!

Ah. I understand. I also feel a bit stupid as I understand I have used the expression "of course" in a wrong way houndreds of times. Thank you for pointing me to this. All I can do is to hope for understanding readers.

This I can not understand. Are you really expecting pattern noise at, for example, neutral backgrounds like in Alexandras portrait or Photo_mom's kitchen? Why would you - it hasn't been seen in pictures from any other camera using this sensor. (I'm not going to discuss this a lot as the discussion at DPR is enough to me.)

regards, and thanks again!

However what I find odd is its lack of persistence. In some cases I can see it quite clearly and sometimes its simply unobtrusive. I hope they come up with a fix but its not really spoiling my fun - this camera is too noisy at ISO1600 to make using it a regular occurence, but at ISO1000 I dont see the pattern unless I push the exposure. Having ISO in 1/3 stops is great too. I find ISO640 a great compromise between speed and noise.

I also find Photolab provides far cleaner high ISO images than ACR with less VPN as well.

Steve,

Really nice images here. Loved the first shot and think the second has excellent graphic appeal. Nicee to see the camera is working for you. Great job. Wish mine was

Works fine without the grip.

Stephen

Yes, I also wondered about that. Herb explained that the VPN always is there, GordonBGood has showed it is caused by a hardware problem. (Re: VPN/HPN feel like hardware issues to me: Pentax SLR Talk Forum: Digital Photography Review)

My impression is that the level of VPN varies between cameras, or maybe it is due to something I can't identify.
Ordinary noise is easier to live with and I also like the gradations/tonalities in the K10D pictures. I wonder if Pentax ever will confirm the VPN or just make a K11D or something sooner than expected?

There is a very real possibility that the problem is inherent in the hardware configuration and therefore varies by individual camera because of component variation. As a result it may not be easily fixed in firmware (post correction) because of that variation or because it affects colour gradations or accuracy. I suspect if they could fix it without recalling all the cameras they would, but if they can't, to admit to a general problem would be suicidal given that no reviewers have made much of it..

I would expect the issue to be absent on the K20D or whatever, but that does not reduce my enthusiasm for the K10D all that much as I never used ISO1600 even on the DS or D.
