Canon Patent Application: Canon RF Primes

I know there's been alot of talk about Canon needing to get lower cost primes and lenses out for the RF mount, that not all lenses can be in the $2000-$3000 range.  Take heart, this patent application is meant for you.

In this patent application, Canon describes quite a few lower cost Canon RF mount primes;

• RF 35 F1.8
• RF 20 F2.0
• RF 35 F2.8
• RF 45 F2.8
• RF 35 F2.0

and also making an appearance is a zoom, a Canon RF 16-35 F4.0, a lens I'm certainly looking forward to for the RF mount.
