This could be the patent for the Canon EF 35mm f/1.4L II lens. Egami (translated) spotted a patent filed by Canon that’s related to a 35mm f/1.4 lens that appears to refer to the successor of the Canon EF 35mm f 1.4L USM (price & specs) lens (released in 1998). Not the first patent for a 35mm lens, and there was a rumor that Canon was field-testing a EF 35mm f/1.4L II lens. More after the break.
New APS-C superzooms coming?

There has been a rumor about a Canon 24-70mm f/2.8 IS lens surfacing last year, now Egami (translated) spotted a related patent (referring also to a 28-80 f/2.8 IS lens). This could be a very exciting lens!
Egami (translated) spotted a Canon patent for a 50mm lens with f/1.8 and image stabilization. The patent does in some way fit with a rumor regarding a new image stabilized Canon 50mm lens said to be announced in 2013. Another Canon patent for a 50mm lens I reported about can be seen here. Canon has three 50mm lenses in their line-up: the EF 50mm f/1.2L, EF 50mm f/1.4 and the inexpensive EF 50mm f/1.8. The lens described in the patent will not replace the 50mm f/1.2L nor the 50mm f/1.8, most probably it will replace the 50mm f/1.4 (I don’t think Canon will add a fourth 50mm lens to their line-up).
Egami (translated) spotted a Canon patent for a zoom optic to be featured on PowerShot G and/or S-series compact cameras. Description and performance chart after the break.
