Olympus LC-62E Lens Cap

I was worried it might be loose, but the spring-loaded mechanism clicks on firmly and stays put even in my crowded camera bag. The soft inner lining gives me extra peace of mind against scratches.

The fit on the 8mm fisheye is absolutely perfect—snaps on with that reassuring little click and doesn’t wobble a bit. Tossed it in my bag on a dusty trail hike and the front element stayed spotless the whole time.

Finally, a cap that actually fits the bulbous front of my 8mm fisheye snugly, so no more worrying about dust getting in during hikes. The textured ring on the outside gives just enough grip to twist it on and off even with one hand.
