This is the Photomic (non-AI mount) and works only on older F, F2 and Nikkormats. It does not work on any digital without modification (but it great on mirrorless with an adapter). What is "Nikkor-Q?". "Q" is for "Quat" and means four elements.
The lens is in good condition with moderate wear and works perfectly. The glass is clean and scratch-free. The mechanical action is smooth. Caps are included.
