Fujifilm 16539730 RLCP-002 Rear Lens Cap

The Fujifilm RLCP-002 is the official OEM rear lens cap for the G-Mount system — the large-format bayonet used on all GFX-series cameras and GF lenses. Its sole job is to protect the rear optical element and electrical contacts of a GF lens during transport, storage, and lens swaps, and it does that job with the fit precision you expect from a first-party accessory. At 14 grams and a footprint of roughly 8.4 by 8.6 centimeters, it disappears into a lens pouch or bag. The bayonet engagement is firm and deliberate — the cap seats with an audible click and does not rattle or shift under normal handling, which matters when you are packing expensive medium format glass.

This is a practical purchase for any GFX shooter who has lost or damaged the original rear cap that shipped with a GF lens, or who wants a dedicated spare for each lens in a multi-body, multi-lens kit. Keeping a rear cap on every unmounted lens is a non-negotiable habit in professional workflows — dust or debris on the rear element or contacts can cause autofocus errors or optical soft spots that only become visible in post. The RLCP-002 is the straightforward, no-compromise solution for G-Mount users who want the correct cap, not a compromise. Third-party alternatives exist at lower prices, but for glass that costs thousands of dollars, the OEM fitment is worth the premium.
