I wasn't sure what forum to post this in, I hope this is the correct one. I recently came into possession of my grandfather's old Nikon F4, as well as several lenses and other equipment. I'd really like to start using the lens on my current digital Nikon, but I'm not quite sure what the lens/equipment are or what they do. Any help on the quality/function/type of these lens would be greatly appreciated. Images: . 2. 3. 4. 5. 6. 7. 8.
