Snap-on lens cap for 49 mm filter threads

The JJC LC-49 is a snap-on lens cap designed for lenses with a 49 mm filter thread. It shields the front element from impact, dirt and dust when the camera is not in use. The cap fits Sony Alpha A3000, NEX-7, NEX-5N, NEX-5R and NEX-3N models as well as Pentax lenses sharing the same thread size. It is a simple protective accessory for everyday carry.

Lightweight protection with no moving parts

The cap adds negligible mass and requires no power, so it has no thermal output, fan noise or electrical draw. Its plastic construction snaps directly onto the filter threads without a separate holder or adhesive. In normal handling it stays secure during transport and storage. There are no mechanical components to wear out or generate sound.

Secure fit during extended storage

Under sustained load such as long periods in a bag or on a shelf, the friction-fit design maintains its grip without loosening. The cap continues to block dust and accidental knocks for the duration it remains attached. No degradation of the snap mechanism occurs over time. It remains effective for as long as the filter threads are undamaged.

Questions about this item

How do I install the snap-on cap on a 49mm filter thread without it popping off?

Align the inner claws with the front threads of the lens, press evenly at opposite points until you hear a click, and avoid pressing only the centre — that leaves one side unlatched.

What maintenance or replacement will the LC-49 need over time?

The plastic spring tabs lose tension after repeated snaps; if the cap falls off when tilted, replace it rather than bending the tabs back.

What is the first limit that appears under sustained daily use?

The snap mechanism fatigues before the body cracks, so the cap stops gripping the 49mm thread securely after several thousand on-off cycles.
