Hi all.

I've done a few shoots and can get some really sharp pic, and then some that look sharp until I view sections of them 100%, then its obvious they are pretty soft.

I decided to do a test with 3 lenses. Tamron 17-50, Tokina 50-135 and a Nikkor 50mm, all at 50mm focal length, at a variety of apertures. I've got 16 crops of the photo I took. All were done on a tripod.

I am not overly happy with any of them, although a couple I would say are acceptable.

Advice as to why these are all so soft would be great. The camera (D90) is near new with 1200 or so actuations on it. Am I expecting too much at full size to expect great sharpness???

Rather than post them all in a thread I've posted the link to the set on Flickr if people would be so kind as to take a look for me.

It would be appreciated as I'm getting a little put off about my photography not even being able to get sharp photos most of the time.

Thanks a lot.
