I feel my D300S is producing way too many soft images. I am using a Sigma 150-500 lens and even tried some macros with my Nikkor 105 VR lens. But the issue is still the same. Here is one example that i would like you all to see. Subject was about 20 ft away from me. The camera was set to single point focus and the focus point appoximately near the eye area. Shutter speed 1/125sec, ISO 400 and F6.3. Camera was on a monopod and i took real care in proper holding of the camera. I am not really happy with the sharpness of the result. What do you think?
Is there anything i can do check if the camera really has focussing issues?
I would like to see a crop of the pelican shot showing just the birds head. At this size it looks like focus is good. I can make out pupil of his eye.
1/125s is a pretty slow shutter speed @ 450mm even with a mono pod so that could contribute to some softness.
The image looks to be exposed fairly bright, almost over exposed. This kind of washes out the image a bit. Try bringing the exposure a little in post processing and then increase the contrast. The image may actually be a little sharper than it looks right now.
Same with the wood duck. Decrease the exposure a bit and add some contrast. It looks like he was pretty close to you and focus locked onto his neck. The lens was wide open so his bill and eye are just outside of the DoF.

They look good to me. One thing about shooting at 500mm is that you actually have very little depth-of-focus at f6.3. Also, 1/125th of a second may be a little slow, even taking care and using a monopod.
I checked a depth of focus chart, and DOF at 500mm at 20 ft. and f6.3 is actually only about one inch!
