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.

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.
Metal body
Rigid Where It Counts
A precision metal body keeps the eyecup slim, stable, and perfectly aligned.
Silicone padding
Soft Where It Matters
Silicone padding adds comfort, grip, and gentle protection for glasses.
Better light
Sealed, Not Bulky
Blocks stray light without oversized rubber housings.
