As it is known, Canon EOS R1 was already one of the high-end models that we expect the company to announce in 2022. In addition, it is among the rumors that the new RF-mount DO super-telephoto lens may be announced with a possible development announcement along with the EOS R1.
Canon is currently testing 5 DO super telephoto lenses, but only one lens will enter final mass production. From the current actual test, the RF 500mm F4.5 DO IS USM performs well.
5 DO Super Telephoto Lenses:
- RF 400mm f/3.5 DO IS USM
- RF 400mm f/4 DO IS USM
- RF 500mm f/4.5 DO IS USM
- RF 500mm f/5 DO IS USM
- RF 800mm f/9.5 DO IS USM
Regarding DO lenses, Canon has developed a micron-scale diffraction grating layered structure, which uses reverse thinking to control the optical path by using the diffraction phenomenon that usually reduces image quality. One DO lens can achieve the compensation effect of fluorite lens and aspheric lens. The use of DO lenses can compensate for chromatic aberrations, achieving high image quality and miniaturization of the lens.
Here are therumored specifications of the Canon EOS R1.
