Promaster 4316 ソニー/マキシマム対応リアレンズキャップ

Snaps on my Maxxum lens with a satisfying click, and the custom fit keeps dust off the rear element. Exactly what I needed for storage.

Finally found a rear cap that actually fits my Sony lenses perfectly without that annoying looseness. The dust protection is solid and the plastic feels durable enough for daily use in my camera bag.

Snaps on tight with zero wobble, which is exactly what you want when you're tossing lenses in a bag. The custom fit for the Maxxum mount means no dust sneaking in around the edges, and it's held up fine after a few months of regular use.
