Bad copy of 24 f2.8D?
5 months ago

After reading the reviews at photozone, I decided to try one of these and just did a few test shots out in the back yard. The first sample is at f5.6 and the other at f8.

Is this lens really this mushy/bad in the corners at these settings or do I have a bad copy? It is a used lens, so maybe it has something wrong with it. I understand that I could expect this wide open but not at these settings.

These are 100% crops but even in the thumbnail of this crop, it's super mushy at f5.6. The upper corners near infinity also are mushy like this and all 4 corners are the same. Even at f8 it's not great by any means.

I guess my question is: Is this normal and all one can expect from this lens on FX or is this a bad/defective copy.
