Canon Patent: 50mm f/1.8 Image Stabilized 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).
