Product Overview

Built for shooters who actually use their gear, the Pentax K-Mount Rear Lenscap is a simple bit of kit that quietly does an important job. Clip it onto any Pentax K bayonet lens – AF or manual – and it seals off the rear element and contacts from dust, grit and moisture when the lens is off the body. The snug bayonet fit won’t rattle loose in a pack, so your glass stays clean and ready to roll.

Moulded from tough black plastic, this cap is light, low-profile and happy to live on your lenses full-time between shoots. Whether you’re swapping lenses on a windy beach, working out bush, or just storing a spare zoom in the cupboard, the Pentax K-Mount Rear Lenscap keeps the business end protected so you can focus on shooting, not cleaning.
