Has Canon finally eased up on third party RF lenses? New Tamron patent suggests so

It’s no secret Canon can be pretty difficult when it comes to allowing third-party lenses for RF mount cameras. Compared to other brands, very few exist and the ones that do don't feature autofocus. However,  there is hope on the horizon that Canon could be easing up on restrictions as a patent for a Tamron 17-50mm f/4 lens has emerged.

Tamron and Sigma arguably make some of the best third-party lenses for Sony, Nikon and Canon EF mount but as things stand, there isn't a single lens available for RF-mount Canon cameras from either brand.  When it comes to wide-angle lenses, there's the Canon RF-S 18-45mm f/4.5-6.3 IS STM for APS-C systems such as the Canon EOS R50 or the Canon EOS R7 but nothing even close for full-frame systems. For anyone who shoots landscapes, portraits or street photography, a 17-50mm lens would be a versatile choice and I'd hazard a guess it won’t break the bank either.
