2nd Tokina 11/16 ... this one soft in the lower left corner
Dec 28, 2011

I just received an exchange Tokina 11/16 ... from B&H Photo ... great service.

The first one was soft in the upper right hand corner at 2.8.

This exchange one is soft in the lower left corner at 2.8 ... more so then the first one in the upper right.

Is it possible to get one that is evenly sharp?! I understand that at 2.8 the edges aren't going to be great, but this one is very soft in the lower left. The corners that are sharp are quite decent.

Am I chasing my tail or should I keep sending them back until I find one that is acceptable?

I do use my lenses for docu work and often have to shot wide open.

Here is a snap from the first 11/16 in the field, at 2.8 ... where edge sharpness isn't too important:

And here is the full size file of the new lens, at 2.8 ... check out the left hand corner:
