A lot of lenses coming for the Canon EOS R full frame mirrorless camera system.…
An image of the upcoming Canon RF 50mm f/1.8 STM already leaked, now we also have the lens diagram.
The leaked lens diagram shows a lens based on a new design, and not simply adapted from the EF 50mm f/1.8 STM. The RF 50mm f/1.8 is a nice and small pancake lens and I am pretty sure it will sell like hot cake (if it has the same reasonable price as the EF 50mm f/1.8).
We expect the Canon RF 50mm f/1.8 STM to be announced within a few days.
