Santa brought me a Nifty Fifty for xmas, and while it's a nice bit of kit I can't seem to get a decent AF out of it on my 1100D, is it just me expecting too much from it? Even going to manual I find it extremely difficult to get sharp snaps out of it, and the tiny viewfinder makes focussing quite hard work as it is. I'll have to post a sample up once I'm back home, maybe it's just me expecting too much sharpness out of it. Anyway, my question is, has anyone come across a lens which didn't quite focus right? I'm presuming it's a lens problem, as the others I've tried have all given decent sharpness and AF performance.
