105–280mm · f/4.2
The Leitz Vetzlar Vario-Elmar-R 105-280 mm f/4.2 is a heavy, well-built telephoto zoom from the late R-mount era, with an over-engineered tripod collar. Optical performance is decent but not apochromatic, showing noticeable blur and color bleeding on some subjects; best results are around 200mm, with weaker performance at 105mm and 280mm. It handles well with a winder for balance, but its weight and size are drawbacks. Suits Leica enthusiasts seeking a unique, solid zoom, though it is expensive and not as sharp as primes or the APO 70-180/2.8.
