Overview

The UV Topcor 100mm f/4 is a compact, lightweight short telephoto lens introduced in 1963 and never updated. Optically, it is quite usable on APS-C, offering good quality for its low cost, though not among the best lenses. It lacks an aperture ring, requiring adapters that supply that function, and adapting is difficult due to scarce adapters. The lens suits budget-conscious users seeking a small telephoto for mirrorless cameras, but those needing modern performance or easy adaptation should look elsewhere.
