Overview

The Industar 100U 110mm f/4 is a compact, lightweight lens with good build quality, though its aperture ring can be stiff. Optically, it delivers sharpness in the center but shows softness and vignetting at the edges, especially wide open. Chromatic aberration is noticeable. It suits users seeking a small, affordable telephoto for film or digital, but not for critical edge-to-edge sharpness.
