If this is the lens that came with the Nikon FM3a I can recommend this lens. Very small and it's a beauty.

No, this is the earlier one from the '60s-'70s. It would not fit on the FM3a. A very nice lens, however!

Nope...what you see is what you get.

The HN4 is a very rare shade that was an optional accessory from Nikon.

The HN35 can be used as an alternative and is a bit easier to find. If you can find a wideangle rubber 52mm screw in shade, that might work.

Interesting note about this lens - the GN is for Guide Number. I forget how it worked, but IIRC, the focus distance related to the guide number of the flash unit, and gave you the exposure, or set the aperture for you, I forget. I was working in a camera store in D.C. when it came out. It was not a widely popular lens, and self regulating strobes kind of made it unnecessary, but folks who had them really loved them.

The aperture and focus are coupled. You set the guide number of your flash, and focussing the lens automatically selects the correct aperture for that distance. It's a tiny sharp lens, very near the format diagonal of 43mm. It focusses in the opposite direction compared to other Nikkors.

It's a very sharp lens, and is highly thought of for macro work by using a BR-52 ring to reverse mount the lens on the camera. On my GN Nikkor, the coupling between distance scale and aperture can be uncoupled, so the lens then operates as a normal lens would. George is right that auto flashes reduced interest in these lenses, but auto flash relies (for the most part) on measuring reflected light from the subject. With a GN lens, aperture is based solely on distance, which can be a boon if you're shooting outdoors or in weird reflective situations. Grab a wet-cell Hobby flash, toss on your GN lens, and you're ready for anything.
