Yongnuo has officially announced their first RF mount lens. It’s the YN RF 85mm f/1.8R DF DSM and it’s actually equipped with a configurable control ring. Despite a number of other lens manufacturers producing RF mount compatible lenses, this marks the first 3rd party lens to actually include a control ring, which has so far been found exclusively on Canon’s own RF lenses.
A few reviews for the lens have already been popping up online over the last week or so, but the lens hadn’t officially been announced yet. It just kind of quietly slipped out. It’s the same optical formula as their 85mm f/1.8 for Sony FE, but in a whole new housing that shows some nice improvements over the FE mount design – like a weather sealing gasket.
