I picked up a used AF Nikkor 35-70 1:3.3-4.5 for $35.00 so really cheap. I didn't have to much time to test it out too well. But I am wondering if it was so cheap because it's just not that great of a lens. It doesn't seem to be that sharp and I get quite a few blurred photos in comparison. Anyone have this lens and have any tips for shooting with it?
