    Overview

    The Leitz Canada APO-Telyt-R 180mm f/3.4 is a compact, well-built telephoto lens originally designed for military use. It delivers excellent sharpness across the frame, with slight corner softness wide open and minor lateral chromatic aberration easily corrected in software. Longitudinal chromatic aberration is virtually absent, justifying its apochromatic designation. Vignetting is noticeable but correctable, though IBIS can cause asymmetric vignetting. 1970s coatings may reduce contrast in backlit scenes. It suits users seeking a high-performance, affordable ($500-$100) 180mm lens for landscapes or distant subjects, especially on Leica SL or Fuji GFX.
