ソニー ボディキャップ（Eマウントカメラ用）

I was worried a body cap would feel flimsy, but this one's anti-scratch shell is surprisingly solid and clicks on perfectly every time. It's lightweight enough that I don't mind carrying it in my pocket, and it keeps the sensor dust-free.

I've had plastic caps warp on me before, but this one's anti-scratch shell feels solid and stays put on the lens mount. It's so light I forget it's there, yet I trust it completely when the camera's bouncing around in my bag.

The shell is so lightweight I almost forget there's even a cap on the lens, but the anti-scratch surface gives me peace of mind tossing it in my bag.
