Canon RF 200mm f/2 patent

RF 200mm f/2 Patent Filed in Japan to the Cheers of the Canon Faithful

In March, PetaPixel reported that Canon intends to release seven or eight RF lenses per year, which is a pretty aggressive release schedule, helping Canon catch up to the more than 70 EF lenses that were available when the EOS R system launched in 2018. A pair of EF lenses that have yet to make their way to the RF system are Canon's EF 200mm f/1.8L USM and EF 200mm f/2L IS USM fast primes.
