See anything wrong with my Nifty Fifty?

Shot at about 3' on a tripod. No PP except convert from RAW to jpeg and USM of 250,0.3,1 and small amount of crop. Focus was between the u and z.

Was your Nifty exactly level with the bottle?? Was the bottle perfectly verticle??

It looks softer at the bottom than I'd expect. f/4 at 3' and 50 mm on a cropper should give about 2" of depth of field. If that image isn't cropped much, it should look sharp the size it is.

The bottle was sitting on a counter. Doubt the lens was exactly level with the bottle. It was sitting on a tripod in portrait orentation.

Well technically the depth-of-field in curved so it explains why the the center seems quite sharp and then gets slightly less sharp the further from the center.

Any advice or link to how to properly test the lens? I posted some pics in another thread and some said that the pictures seemed blurry. Not just OOF.

This photo looks great. Go shoot with it and stop worrying. Tests will just drive you nuts. Do you have any reason to think there's anything wrong with it in the first place? Blur can be down to a lot of things, most likely camera shake.

Yep,, shoot everyday situations at different apertures.. Don't forget to do a few tests in manual focus as a bench guide..

Thanks guys. More than likely was me that was causing the blur. I was just walking around shooting some interesting doors. Doing it rather quickly so the homeowners wouldn't get in a tizzy. Just worried me a little.
