Promaster 7732 Sony E 接環機身蓋

I was glad to find a cap that actually seals tight instead of feeling loose. The custom fit for the Sony mount gives me confidence it’s keeping dust out while stored.

Snapped this on perfectly the first try—no wobble, just a snug fit that feels secure. Exactly what I needed to keep dust off the sensor when swapping lenses.

Took my camera out for a shoot and left the lens off for a bit—this cap kept the sensor spotless the whole time. The custom fit for my Sony E mount is spot on, no wiggle or gap. It's the kind of cheap insurance I should've bought months ago.
