We were told that three new fast L primes will be announced for the RF mount in early 2020. They include an RF 24mm f/1.4L USM and an RF 135mm f/1.8L along with an undisclosed dedicated macro lens which will be a “first of its kind macro lens”, though no details of what that means was given. I wouldn’t read too much into the latter.
The three new lenses are scheduled to be announced before CP+ in 2020, but as always, take lens scheduling with a grain of salt.
A lot more lenses are planned for 2020, we could see as many as 8 new RF lenses in 2020.
