Promaster ボディキャップ - Lマウント (パナソニック、ライカ、シグマ)

Fits snugly on my Sigma FP without any wobble, and the inner lip catches the mount ring perfectly. It's a simple piece of plastic, but it does exactly what it's supposed to for keeping sensor dust away during storage.

Popped this on my S5 and it clicks into place perfectly—no wobble like my old cap. The tight fit gives me peace of mind when I'm swapping lenses outdoors.

Finally, a body cap that fits my Panasonic S5 perfectly without any wobble. It clicks into place with a satisfying feel and keeps the sensor covered securely. Exactly what I needed for simple storage.
