So as I was scouring the various lens threads and I noticed this post:
Originally posted by Digitalis In regards to sharpness, I think on the K-7 the AA filter is a bit too heavy handed. I don't know about the AA filter on the K20D but on the K10 the sharpness of the FA31 is staggering. .
AFAIK, the K200d's sensor is the same as the K10d's so i thought I'd compare. Secretely, I've felt all of my images are softer since i got the K-7. Especially my macro images. Infact, Before getting the k-7 i took some images of a katydid with the k200d. When the K-7 arrived i found another the same size and type, so i decided to take some macro's. Using the same settings and setup and good focus for both the k-7's was softer viewed ~50%. Obviously the k-7's 50% is closer than the k200d's, but even if i compensated for this the K-7 was still noticeably softer. This was comparing JPG's, of which I no longer have to post here.
So anyways I took the old tripod, K200d, K-7, and K 50mm F/1.2 outside. I setup a simple leaf on my glass table and kept it place with tape. Here's the results:
Straight out of the camera Jpegs All Jpeg settings for each camera were the same
K-7 @ F/1.2
crop:
K200d @ F/1.2
crop:
The images were taken by shooting the first shot with the k200d w/ split prism focusing screen, than switching the lens onto the k-7 and used liveview to mimick the same focus point. Clearly the K200d's image is sharper.
Now for F/2 shot:
K-7 @ F/2
crop:
K200d @ F/2
crop:
again, same deal. So my question.... WHY??? What does the K-7 gain by doing this?
So anyways I shot in RAW plus as always, so I thought to myself maybe it has something to do with how each camera processes Jpeg's... something I can't control. Therefore I threw the 4 images into UFRAW and made sure all of the settings were EXACTLY the same. No sharpening, nothing.
I'll just post the full F/2 shots for your sake
K-7 @ F/1.2 crop RAW
K200d @ F/1.2 crop RAW
and at F/2
K-7 @ F/2 RAW
crop:
K200d @ F/2 RAW
crop:
So less so in RAW, but the k200d is still producing sharper images :ugh:
Kind of makes me want to go out and buy a K10d to be honest
Just thought I'd share.
