What it does
• Glasses Protection: The Slim M Eyecup helps shield your glasses from scratches, keeping your lenses safe while you shoot.
• Rangefinder Protection: It adds a barrier in front of the rangefinder glass, protecting your camera from dust and elements and reducing the risk of costly repairs.
• Enhanced Comfort: The padded surface gives a soft resting point for your eye or glasses, making longer sessions more comfortable.
• Better Frameline Preview: Enjoy a full preview of your 35mm, 50mm, and 28mm frame lines while staying closer to the rangefinder. (Disclaimer: Overall frame line visibility may vary based on the position of your glasses.)
Smaller Lighter & minimalist
• Crafted with Quality: Machined from solid aluminum or brass and available in finishes like Black Patina, Brass Bead-Blasted, Black Chrome, or Silver Chrome, each eyecup is proudly made in Miami, by photographers for photographers.
In short, the Slim M Eyecup combines comfort, protection, and a minimalist aesthetic, all in one

Installation
The installation is very simple. Thread the eyecup directly into your digital Leica M rangefinder eyepiece. Do not over-torque. Gently screw it in until a snug, secure fit is achieved.
Framing with Glasses Notice: The EyeKup improves contrast and focus refinement by sealing peripheral light. When worn with glasses, any eyecup adds eye-to-finder distance, which may limit visibility of wider framelines (28mm, sometimes 35mm). Results vary by eyewear fit and facial anatomy.
