Feeling like a complete noob here, but does the 50mm 1.8 nikkor lens NOT AutoFocus on Nikon D3100 body? Or is my lens broken?
This is a new lens that I bought months and months ago and forgot about... pulled it out today and hmmm no AF...
I wouldn't otherwise mind, except I want to use it on moving subjects...
The info sheet that came with it said it was compatible with D300's and I just assumed that included the 3100..
