Do you need to test sharpness? Have you bought the lens? If you have, forget sharpness tests. If you haven't, ask for a 50D and shoot text.

bought liao, but shop owner very nice, she allow me to bring it back to do a proper test within a week, if not ok, can bring it back for exchange when new stock arrive. i'm usin 40D atm... when i shooot text, not sure if it's doin the lens any justice if i zoom in all the way like 200%. or shd i just zoom to 50% or 100%? when i dun zoom at all, the pic in general looks pretty much sharp... i'm not fussy, but just wanna take the opportunity to learn how to look out for softnest of the lens, especially a UWA lens... TIA;)

If at 16mm f/2.8, you shoot a piece of paper and the text is sharp at 100% crop, then be happy with it.

Glad to help. Oh, don't mix up sharpness for CA (the purple / red edges). The tokina 11-16 is known to have that. In fact, it's the only thing that's not as good as Canon's 10-22.
