I have a really dumb question about an AF Nikkor 75-300mm 1:4.5-5.6 (japan) I picked up from cash converters for the princely sum of $40.
It is not pristine, but takes great sports shots.
I have a Nikon D3000 so of course it won't autofocus this lens. But I cannot seem to manually focus it on what I want at full extension at 300mm.
Am I correct in assuming that this problem is simply the aperture limits of the lens - I am optimistically trying to shoot too far beyond the distance that the aperture will allow the lens to bring clearly into focus?
Also, my bonus dumb question - what does the slider marked "full" and "limit" do?
