What is "Nikkor-Q?". "Q" is for "Quat" and means four elements. This lens is non-AI and will not fit any modern SLR (but would be great on a mirrorless with an adapter).
The lens works well. There are a few fine cleaning marks on the front element, but they won't affect your image quality. Otherwise it has clean scratch-free glass. The mechanical action works well. There is moderate to heavy cosmetic wear but it is just cosmetic.
The lens caps are included.
