M42 Lens Mount to Canon RF Camera Mount

I have shot a few times using the adapter since receiving and has worked great. Nicely packaged and simple to use plus they’re planting trees to help the environment!

Perfect

Almost...

The adapter, itself, is very solid. Nicely polished and built. M42 lenses fit like a glove. However, notice something about the Viltrox and Canon adapters and yours? Yeah, they have caps, yours doesn't. For the prices charged for your adapters, you could include some caps. So great adapters, but missing a key component.
