JJC 43mm Front Lens Cap Cover + Elastic Anti-Loss Cap Keeper Leash for Canon EF-M 22mm f2 STM, EF-M 28mm f3.5 is STM, RF 50mm f1.8 STM, XF 35mm f2 R WR, XF 23mm f2 R WR Lens & More 43mm Thread Lenses

Excellent. This is better made than the one 3rd party lens cap I lost. This one also has more features such as an elastic loop with a cord and adhesive tab. I lost my other lens cap because it did not have a tether like this one. This was ordered for a fujifilm and it is a perfect fit into the lens. The fit is perfect and very tight and secure. The cap seats deep enough into the rim of the lens. When I seat this cap into a same size 58mm diameter Hoya filter on the lens, the cap still attaches well, but does not seat as deeply because the external rim of the filter is not as deep. Wonderful price for a high profile lens cap.

I wanted a nonsticky way to attach my lens cap to my lens. This works great using elastic strap. Fits perfectly on my wide angle lens.

Fits the sony zv-e10

I lost the lens cap to my Olympus 14-42. This cap actually fits better and doesn't want to pop off. Just make sure you order the right size.

I bought this and the Olympus CLA-T01 conversion lens adapter ring at the same time. What I didn't know is that the CLA-T01 also comes with a factory Olympus lens cap that snaps into the adapter ring. This JJC 40.5mm lens cap also snaps in just like the Olympus cap but the JJC is about twice as thick. If you have an Olympus or OM Systems Tough camera, and are planning on buying the lens adapter ring, don't bother with this JJC cap. You will most likely prefer the Olympus cap like I do.

Perfect Fit: from the looks, the material looks better than the original Cannon cap; better grip clips make it easier to use and install

Accurate as given in the description. Durable. Nice build quality

The Lens cap does not clip on strongly enough to the Lens and easily falls off. It needs more depth
