Sony ALCF82S.SYH 82mm Front Lens Cap Black

The Sony ALC-F82S is a genuine Sony front lens cap sized for any lens with an 82mm filter thread. Its center-pinch mechanism lets you squeeze two tabs at the center of the cap to snap it on or off, which is especially convenient when a lens hood is mounted — unlike rim-pinch designs, you do not need to reach around the hood to grip the cap's edges. The cap sits flush against the front element and holds firmly enough to stay in place inside a camera bag without accidentally popping off.

Build quality is what you would expect from an OEM Sony accessory: the plastic is sturdy without being bulky, and the pinch tabs feel positive with each squeeze. At 82mm it covers some of Sony's larger lenses as well as third-party glass with the same filter diameter. While it is a simple accessory, using the correct-size genuine cap avoids the loose fit and easy-to-break tabs that sometimes plague off-brand alternatives, helping ensure your front element stays protected between shots.
