Nikon BF-1B 鏡頭接環機身蓋

Perfect fit on my D7500 — snaps on firmly and the inner baffle does a great job blocking out dust. Feels solid enough that I don't worry about it popping off in my bag.

The click when this cap seats into the F-mount is so reassuring—no wobble, no half-latch, just a firm snap that tells you the sensor is sealed. I've left it on for weeks between lenses and blown off zero dust when I swapped back. It's a tiny piece of plastic but it does exactly what a body cap shoul

Finally a body cap that snaps on securely without that cheap, loose feeling. Keeps the sensor dust-free even when I toss the camera in my bag.
