Tamron リアレンズキャップ Sony A (v2)

The dust seal fits tight enough that I don't worry about pocket lint getting near the glass. Snaps on with a satisfying click and stays put, even when tossed loose in my camera bag.

Better than the generic caps I've used before—this one clicks on firmly and covers the rear element completely. It fits my Sony A-mount lens perfectly and gives me peace of mind against dust.

Fits snugly on my Sony A-mount lenses, which is exactly what I needed. The plastic feels durable enough for regular use, though it’s a bit stiff to remove at first. Still, it does the job of keeping dust out.
