This is a vintage
Tokyo Kogaku Japan lens, 1268424 ~ UV Topcor ~ 1:4 ~ F=200mm. Please check my
other and future listings for more vintage camera lenses and cameras. This lens is clean, has a slide out lens hood and
is very smooth when turned. My online research shows it first came out in 1967
and is no longer made. It is part of the UV Topcon system. Great for wildlife
photography!
