ProMaster Rear Lens Cap-Canon RF

It's nice to have a cap that clicks securely and feels solid, not like the flimsy ones that warp over time. This one fits my RF lenses perfectly and keeps the dust off.

I was tired of caps that barely stay on, but this one clicks into place with a reassuring snap every single time. The fit on the RF mount is perfect and my rear element finally feels properly sealed against dust when I toss the lens in my bag.

Finally, a rear cap that doesn't feel like it's going to pop off in my bag—the snug fit gives me peace of mind when swapping lenses. The dust seal is much tighter than the generic ones I've used before.
