good solution!

I have an old sigma 1.4 30mm lens, and wanted to attach it to my EOS R camera, but with the original canon adapter that doesn't work because the old lens makes the wrong communication, and the camera doesn't even work than. Now I bought the Urth EF to RF adapter, and because it has no contacts at all, there can be no mis-communication, and so I can use the lens manual focus, and only with aperture in fully open position, but that is fine with me because I like the lens for portraits with blurry background. Good Solution!

Tight fit, no issues with the adapter

I have used this on a couple of lenses for my DSLR, and have had no issues. The fit is tight and snug, and I would recommend this to anyone looking for a cheap and affordable manual adapter.
