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.

Questions about this item

Which body-cap version should I pick for a 39 mm screw-mount camera?

This single silver anodised-aluminium cap fits both M39 and L39 39 mm threads, so there is no separate version to choose.

What does the 39 mm thread spec mean when the cap is on my camera?

It matches the 39 mm pitch of M39 and L39 bodies, sealing the mount against dust and light when no lens is attached.

How does the M39/L39 screw interface limit what the cap can do?

The cap only protects cameras with a 39 mm screw mount; it will not fit bayonet or larger-thread bodies.
