(Please note that I shoot Canon and I am not familiar with Nikon)
I don't see very much information on this lens. I was curious if anyone can help me. Should this lens autofocus on a D3200, or any camera for that matter? I am asking because when I search this lens I find that most the tab to choose autofocus, but the lens I have does not and no where on the lens does it say autofocus or AF and it will not AF on the D3200. I don't have another Nikon camera to test it on. Thank you in advance.
