Promaster 6814 ボディキャップ - Lマウント (Panasonic, Leica, Sigma)

Snaps securely with a satisfying click and fits my Sigma fp perfectly—plenty of clearance for the mount. Much sturdier than the flimsy caps that come with some lenses.

Finally a body cap that snaps on and off without feeling like I'm going to break the mount. The plastic feels dense and solid, exactly what I need for quick lens swaps in dusty conditions.

The fit on my Panasonic S5 is perfectly snug, so I feel confident it's keeping dust out during storage. The plastic feels sturdy enough for tossing it in my bag.
