Fotodiox silver metal body cap for M39 and L39 screw mount cameras

Silver M39 body cap — protection for screw-mount

This Fotodiox cap covers the 39 mm thread on M39 and L39 camera bodies when no lens is attached. It is machined from anodised aluminium with a silver finish. The cap shields the shutter, sensor and mirror box from dust, moisture and accidental impact during storage or transport. It is a low-cost way to avoid expensive repairs on vintage or modern screw-mount cameras.

Owners of M39 or L39 bodies needing a durable

Photographers who use Leica screw-mount, Voigtländer or other 39 mm thread cameras will find this cap a direct fit. Collectors storing classic rangefinders gain a metal cover that resists wear better than plastic originals. Shooters whose cameras use bayonet mounts, different thread pitches or proprietary body caps cannot use this accessory.

39 mm screw thread — the only fit that matters

The cap threads onto any camera body with a standard 39 mm × 1 mm pitch (M39/L39) mount. No other diameter, pitch or bayonet type will engage. Verify that your camera specifies M39 or L39 before purchasing.
