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 clean condition with hardly any wear and works perfectly. The glass is clean and scratch-free. The mechanical action is smooth.
Caps are included. This is a nice one.
