I did a shoot with the Tokina 11-16mm f/2.8 on my Nikon D5000. Most of the pictures came out good but a lot of them weren't as sharp as I would like. I used that lens because it was a shoot in a poorly lit nightclub and small spaces so I needed something fast and wide.
I am thinking they didn't come out sharp due the the shallow DOF from shooting at f/2.8, am I correct?
