Lens mounts.
The patents deal with the optical style of the lenses as well as do not signify the lens install. However, one of the most very likely choice would be actually Canon's radio frequency install. Furthermore, Kengo Iezuka, who manages preparation lens at Canon, provided a meeting concerning radio frequency lenses just recently.

What we assume.
Till recently, Canon has prevented various other makers from making radio frequency mount lens. Currently the business is beginning to open up the market to other lens producers, Canon needs to maintain innovating. The new licenses reveal that Library is actually working doggedly to establish interesting brand new lenses for its own radio frequency position electronic cameras. However, as always, where licenses are actually concerned, it is actually additionally essential to bear in mind that the method is carried out mainly to shield technical growth. The registration of a patent doesn't consistently cause a product coming to market.
