Canon has always had some extreme lens designs, but they really kicked things into high gear when they got serious about the mirrorless world. It seems they have no intentions of slowing down, as another patent for a crazy lens has emerged.
Canon Rumors reported on the new patents recently, which include a 24mm f/1.4L USM DS and 50mm f/1.4L USM DS lens, but the most notable is an RF 135mm f/1.4L USM DS option. The EF 135mm f/2L has long been a favorite of many photographers, but it is well past its prime, particularly being an EF lens, and in the meantime, companies like Sigma have released more modern wide-aperture 135mm lenses. Of course, just because a company files a patent does not mean the product will actually make it to the market, but with the lack of a 135mm option in the RF lineup, I am sure we will see some sort of option soon enough. It is not clear if it will be this particular lens, and if it is, if it will come in a non-DS (defocus smoothing) version as well, but I am sure we will see some sort of 135mm lens eventually.
