Nikon LF-4 Rear Lens Cap

The snap fit on this cap is tight and reassuring every time I swap lenses, and it covers the rear mount completely so no dust sneaks in. I’ve gone through a few third-party caps that felt flimsy, but this one’s solid and worth the few extra bucks for peace of mind.

Fits snugly on my 50mm prime, and the click is reassuring when it locks. It's a simple plastic cap, but it does exactly what it should—keeps the rear element dust-free between shoots.

Snapped it onto my 50mm f/1.8 and it's a snug, secure fit that keeps dust off the rear element. Exactly what I needed to protect the lens when it's not on the camera.
