The adapter seems well made and fits perfectly on my camera. I have found a bit of an issue that requires father experimentation... when I used my Canon 18-200 lens with the adapter to shoot some buildings, the images were a bit distorted, for example a flat roof came out a bit wavy. The auto-focus works so-so, sometimes it takes quite a bit of "zooming" before it lands on the correct focus. Once it does focus, the resulting images are sharp

All good, the quality seems nice, it fits to the body well and the lens attaches cleanly. Infinity focus is supported (not at the infinity mark, but that's probably down to the lens).

I am currently using this adapter with a Fuji X-T3 and a Canon EF 40mm 2.8 STM. I had previously used it with an X-H1 and the performance was good / ok, so I thought it would be better with the more advanced autofocus system of the X-T3, HOWEVER on the latest firmware 2.29 (that is Viltrox) it was so very poor. The X-T3 has the latest firmware 4.10 and the autofocus is now very fast and accurate - on par with native Fuji lenses. For me, the wider field of view and shallower depth of field is worth every penny. Be warned, however, that performance varies by camera/firmware combination.
