Hi Clarence.
I'm not sure what ".pef brought up into Photoshop" means. But several possible issues arise here:
1) .pef is raw & needs sharpening. I assume you are using ACR here. How much sharpening is this set to? My default is very little & then only for on screen viewing - files saved or opened into PS have no sharpening applied.
2) Screen capture... PS has to interpolate the image to show it on screen at anything other than 1:1 actual pixels. My understanding is that this interpolation isn't very good except at 50%, 25%, etc. Save as JPG. Don't use a screen capture as that adds nothing except a high probability of image degredation.
Shooting raw is great. It sounds like you need to learn a good sharpening work flow. Here's what I cut my teeth on: http://www.creativepro.com/story/feature/20357.html
At least 2 more issues here:
1) f22 is likely diffraction limiting the sharpness of your image. Do you really need that much DOF? Max DOF does not equal max sharpness. Try f8 or so.
2) How long was the shutter open? (I didn't try to check your EXIF.) As this appears to be an outdoor shot, are you sure there was no motion from a breeze or such?
I'm not convinced anything's wrong with your camera, but if you are and it needs a new home, cheap.... :lol:
If you want "straight out of the camera" sharp, you'll have to use jpg output and set the sharpening parameters for the in-camera converson appropriately. I suggest seek to improve on your RAW workflow as it's much more flexible & tunable.
Cheers.
