Fotodiox Pro 替換相機機身蓋與後鏡頭蓋套組 - 相容於所有 L-Mount Alliance 無反相機與鏡頭

The snug fit on my Sigma lens mount is exactly what I needed to keep dust out. These caps click on securely and feel sturdy enough for daily use.

I usually hate fumbling with separate caps on set changes, but having the body cap and rear lens cap together in one set is a real timesaver. The plastic feels sturdy enough to trust in a crowded camera bag.

The fit is snug but not stiff, which is exactly what you want when swapping lenses on the fly. I’ve already tossed these in my bag on a messy hike and the rear cap stayed locked on without a hint of dust sneaking past.
