Micro-NIKKOR-P Auto 55mm f/3.5 with M2 Ring

This is a Nikon Micro-NIKKOR-P Auto 55mm f/3.5 lens and M2 extension ring, both released in 1973.

I am selling these items to clear out my collection.

Although it's an old lens, it still delivers good contrast and sharp images. It performs well wide open, so I think it's a lens you can use at its maximum aperture.

The exterior is in good condition with no noticeable scratches. The lens has no mold or fogging, but there is some dust inside. This did not seem to affect the photos I took. The focus ring has a good feel, and the aperture mechanism works well.

The 14th photo is a sample taken with this lens mounted on a full-frame mirrorless camera using a mount adapter. The 15th photo is a sample taken with the M2 extension ring attached.

Included accessories are the front and rear lens caps.

Here are some specifications:
Minimum focusing distance: 0.241m
Reproduction ratio: 1/2x (1/1x with extension ring)
Filter diameter: 52mm
Mount: F mount

M2 Extension Ring
