With the launch of the Canon EOS R – the company's first full-frame mirrorless camera and the start of its true mirrorless ambitions – Canon also brought us a brand new mount for a whole new series of lenses: the Canon RF mount. This was the biggest change for Canon in over 30 years, since it swapped from the FD to EF mount in 1987, introducing electrical contacts for a new wave of electro-mechanical photography.
With this new RF mount, Canon talked big about how the decreased flange distance and upgraded electrical contacts would unleash a wave of lens design that was never possible before. To crown this achievement, alongside the EOS R the manufacturer launched, the Canon 28-70mm f/2L USM lens – one of the most remarkable optics seen to date. Then Canon went a bit quiet.
