I plan to buy the Nikon AF Zoom-Nikkor 28-80mm f/3.3-5.6G lens for my Nikon D5100. I want to know compatibility, performance and quality of the lens-D5100 combo.
It seems autofocus is not supported for this combination.
Nikon has the following resources with additional information:
This lens uses a screw driven AF, meaning the body drives the AF. The D5xxx series and D3xxx series of cameras need AF-S lenses in order to AF with them.
