The Owlkrown M-EyeKup was designed specifically for digital Leica M bodies that use the M14 × 0.5mm OR M12 x 0.5mm rangefinder eyepiece thread. The goal was simple, cut peripheral light without killing frame line visibility, and stay comfortable whether you shoot with glasses or not.

What it does

The M-EyeKup blocks stray and peripheral light while still letting you clearly see your frame lines, including wider focal lengths. This makes focusing easier in harsh daylight and gives a more controlled, immersive viewing experience without turning your M into a tunnel.

Glasses friendly by design

At the base of the eyecup we added a precision-fit silicone pad. It creates a soft contact point between the metal body and your glasses, preventing scratches while keeping the eyecup stable and comfortable during long shooting sessions.

Why metal + rubber works

• Metal body keeps the eyecup rigid, slim, and perfectly aligned with the rangefinder

• Silicone padding adds comfort, grip, and protection for glasses

• Better light sealing without oversized rubber eyecups

• Comfortable with bare eye or glasses

• Keeps a clean, Leica-correct look on the camera

Finishes

• Black Chrome (Aluminum)

• Silver Chrome (Aluminum)

• Premium Brass (designed to age and patina over time)

• Brass Black Patina (designed to age and patina over time)

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.

Brass Black Patina (Black patina shown in images is for reference only. Each piece is hand finished using an organic process, so the patina will vary from item to item.)

Designed, machined, and finished by Owlkrown.
