Nikon LF-N1 Rear Lens Cap

I was a bit worried about fit, but this cap snaps on securely and doesn't wobble at all on my 50mm lens. It feels like good quality, and the precision fit is exactly what I needed for peace of mind when swapping lenses.

The plastic feels sturdier than the generic caps I've used before, and it clicks onto my lens with a satisfying snap. No more worrying about dust getting on the rear element when I swap lenses in the field.

Finally got around to replacing the cheap third-party cap that kept popping off, and this one clicks on with that solid, precise fit you expect from genuine Nikon gear. The rear element stays fully shielded during swaps, and it's thin enough that it doesn't add bulk when I toss the lens in my bag.
