Originally posted by lawjbm Thanx so much for your replies. I am not able to post more pictures until later tonight, but perhaps I can better explain my perceived issue.
I took pictrures with the Pentax (when on the tripod and table SR was off) the D300 and have some recent Canon 40D pictures. I think I have the visible noise issues more or less figureed out, both in terms of what I need to do to take the picture and the best way to view it on my monitor. I just have to determine whether that is acceptable to me.
Regarding the softness, I am just talking about opening up both RAW and JPEGs in Photoshop and viewing them. The Nikon and Canon pictures look like nice focused pictures. Sure there's a blurry or soft focus photo here or there, but that was because of movement and normal stuff that can affect a pciture. The Pentax under the same conditions used just a few monents later or before almost always, if not always, turns in a slightly out of focus picture. At this time I am not really pixel peeping. Yes, I am looking closely, but not more so than when I am looking at other pictures. I can look at the Nikon and Canon pictures and say those are nice sharp photos. The Pentax pictures, though not terrible, are simply soft(er) despite sharpening and conrast adjustments in the camera and some RAW adjustments. I am pretty good with Photoshop so I do not think I am making post processing mistakes, at least nothing major.
I am shooting at f/5.6 and f/8 for these test shots, though, even at f/2.8 the Nikon lens is better and sharper than the f/2.8 Pentax. The Canon photos were shot with a kit lens.
And when I am looking at 100% cropsof details like hair I think I can account for different resolution/scale and the Nikon sinmply is better. I expect that to some extent. It is a more expensive camera. I di not expect it this much. My hope is that the lens is not focusing properly and if I can get a copy that does than details will be better. The 40D kit lens has better small details. Again, the Pentax pictures are not bad, but all that good.
Any other suggestions are appreciated.
Thanx again.
Well, I don't think you're doing anything extraordinary. In my opinion, the K20D shots should be just as good as the others, not consistently softer. Do you have another lens to use? I don't really pixel peep my DA*16-50 and I've been happy with it. Maybe it's not the sharpest? I don't know.
You should be able to "dial it in" with the AF adjustment, and I know you've tried.
Maybe it's your raw settings? Just for a comparison, try the Pentax Photolab software. That should give a good raw conversion and tell you if ACR isn't converting optimally.
