Overview

The Sony ALCF72S is a genuine OEM front lens cap designed for any Sony lens with a 72mm filter thread. Its center-pinch mechanism lets you attach and remove the cap quickly, even when a lens hood is mounted — a practical advantage over older side-pinch designs that require access to the outer rim. The cap clicks securely into place, protecting your front element from dust, fingerprints, and scratches whenever the lens is not in use.

As a direct Sony replacement part, the ALCF72S matches the fit and finish of the cap that originally shipped with your lens. It is made from lightweight black plastic and features the Sony logo on the front. While it is a simple accessory, having a properly fitting lens cap is one of the easiest ways to preserve optical coatings and keep your glass in top condition for years of shooting.
