According to CanonRumors, Canon may release three RF mount red ring lenses in the first half of next year, one of which may be the long-rumored RF 35mm f/1.2L (or f/1.4), One is the RF 24mm f/1.4L USM, and the third is not yet confirmed, but it may be a 28mm prime lens.
The RF mount is a camera mount launched by Canon, which was launched with the Canon EOS R camera in September 2018.
The inner diameter of the Canon RF mount is 54mm, which is the same as the inner diameter of the Canon EF mount. The flange back of the EOS R and EOS RP cameras is 20mm. RF lenses have 12 electrical contacts, compared to 8 for EF lenses, allowing greater and faster data transfer between the body and the lens.
In addition to physical design, electronic communication systems are equally important. The electronic communication system of the RF bayonet is still exclusively owned by Canon and has not been disclosed to the public. It is convenient for Canon to exercise its patent protection rights and sue manufacturers who infringe the patent rights. Therefore, most of the RF bayonet lenses of the sub-factory are manual.
