Leica 14357 M-1.5 Diopter Correction Lens M-Series

The Leica 14357 M-1.5 Diopter Correction Lens is a purpose-built accessory for photographers who use Leica M-series rangefinder cameras and need mild nearsighted correction at the viewfinder. Rather than squinting through the rangefinder with glasses pressed against the eyepiece — which can scratch both surfaces and limit your view of the frame lines — this correction lens threads directly into the viewfinder and provides a clear, properly focused image of the rangefinder patch and frame lines for users with approximately -1.5 diopter vision.

Constructed to Leica's optical standards, the lens is made from high-quality glass that preserves the brightness and contrast of the M-series viewfinder. Installation takes seconds: simply unscrew the standard eyepiece and thread in the correction lens. Once installed, it sits flush with the camera body and adds negligible weight or bulk. For rangefinder photography, where precise manual focusing through the coincidence image is critical, having the right diopter correction makes a meaningful difference in focus accuracy and shooting confidence, particularly in fast-moving or low-light situations.
