CTOnews.com, December 16 (Xinhua)-- according to CanonRumors, Canon may release three RF card lipstick lenses in the first half of next year, one of which may be the long-rumored RF 35mm f / 1.2L (or f / 1.4L), the other is the RF 24mm f / 1.4L USM, and the third is not known yet, but it is likely to be a 28mm fixed-focus lens.

CTOnews.com learned that RF bayonet is a camera bayonet launched by Canon, which was launched with Canon EOS R camera in September 2018.

The inner diameter of Canon RF bayonet is 54mm, which is the same as Canon EF bayonet. The flange distance of the EOS R and EOS RP cameras is 20 mm. The RF lens has 12 electronic contacts, more than the 8 electronic contacts of the EF lens, making the data transmission between the body and the lens larger and faster.

In addition to physical design, electronic communication systems are also important. At present, the electronic communication system of RF bayonet is still exclusively owned by Canon and has not been made public, so it is convenient for Canon to exercise patent protection and sue manufacturers who infringe patent rights, so at present, the vast majority of vice-factory RF bayonet lenses are manual focus products.
