135mm · f/2.8
The Steinheil Munchen Auto-D-Tele-Quinar 135mm f/2.8 is a compact 135mm lens with an enhanced Ernostar design (5 elements/4 groups). It offers first-class build and image quality, but flares easily when pointed at a light source. Wide open, it shows some chromatic aberration in high-contrast areas, which disappears with slight stopping down. The lens is notably tiny for a 135mm, though aperture blade count may vary. It suits photographers who appreciate vintage character and compactness, but may frustrate those sensitive to flare.
