Quick answer

The right body cap is determined by your camera mount — not brand alone. Kood makes dedicated caps for Canon EOS R, Nikon Z, Fuji X, and Micro 4/3 mounts, each with a specific bayonet shape. For example, the Canon EOS R cap won't fit a Nikon Z body, and vice versa.

Why mount-specific caps matter

A camera body cap seals the lens mount when no lens is attached, protecting the sensor and internal components from dust, moisture, and scratches. Because each camera mount has a unique bayonet lock and throat diameter, caps are not interchangeable between systems. Using the wrong cap can leave gaps or fail to lock, defeating its purpose.

Kood offers affordable replacement caps for several popular mounts. The trade-off is that you must match the cap to your exact camera body — a cap for a Canon DSLR with an EF mount (not covered here) is different from one for a Canon EOS R mirrorless body.

Canon vs Nikon body cap trade-offs

  • Canon EOS R cap (Kood 1906242): Works with Canon EOS R mirrorless bodies and older EOS DSLRs. The bayonet is the same across Canon's EF and RF mounts, so one cap can serve multiple Canon bodies if you own both systems. Best if you shoot Canon EOS R or have a mix of Canon DSLR and mirrorless bodies.
  • Nikon Z cap (Kood 1906247): Made for Nikon's new Z mount. It has a larger diameter than older Nikon F-mount caps, so it will not fit Nikon DSLRs. The high-quality plastic construction adds durability. Essential if you own a Nikon Z6, Z7, Z50, or any Z-series camera.
  • Fuji X vs Micro 4/3 caps: Fuji X caps (Kood 1906250) are smaller and match the X mount's bayonet. Micro 4/3 caps (Kood 1906249) are even more compact and fit Olympus, Panasonic, and other MFT bodies. Neither is interchangeable with Canon or Nikon mounts. Choose the cap that exactly matches your camera mount — no universal option exists among these.

  • Kood Body Cap - Fuji X: Designed specifically to fit Fuji X-series camera bodies. Fuji X shooters can protect their smaller-format sensor with a cap that matches the X mount bayonet, avoiding the risk of using a cap meant for a different system.

  • Kood Body Cap - Micro 4/3: Fits all Micro Four Thirds cameras, providing protection against dust, water, and scratches. Micro 4/3 users (Olympus, Panasonic) benefit from a cap that fits the compact mount, adding a layer of weather resistance between shoots.
