It seems that Yongnuo is the first company to figure out a way around Canon’s RF mount autofocus lens licensing issues. Well, it’s either that or they’re going to be next in the line of companies that Canon shuts down for producing unauthorised, patent-infringing, RF mount autofocus lenses. Either way, it seems that Yongnuo has announced a new 85mm f/1.8R DF DSM lens for Canon RF mount.
According to Asobinet, the lens comes with a new design, new optical configuration of 9 elements in 8 groups, a 7-blade aperture, 58mm filter thread and a minimum focus distance of around 80cm. It is an autofocus lens featuring a built-in stepper motor, which means it presumably communicates with RF-mount camera bodies. All I want to ask is… How? This isn’t the first time Yongnuo’s tried to release this.
