Promaster 4337 Sony/Maxxum 機身蓋

Fits snugly on my Sony body with a satisfying click, and the inner rubber rim creates a solid seal against dust. Finally stopped worrying about debris getting into the sensor during lens swaps.

I was pleasantly surprised by how secure the fit is compared to other caps I've used; it's tight enough that I don't worry about dust sneaking in when I swap lenses on my camera. Nice to have a simple, reliable backup that just works.

Fits snugly on my Sony body, and the tight seal makes me feel better about tossing it in my bag without a lens on. Honestly, for a plastic cap it feels solid enough to trust.
