A new rumor about a possible imminent announcement of a new Canon 50mm lens. No mention of the mount type (previously EF-M was rumored). Canon Rumors got
[...] word from two different sources that a new 50mm lens would be on the way “soon”. One person suggested it would “probably” have IS. No mention of aperture, but judging by past mentions of a new 50mm, it would be a replacement for the near ancient 50mm f/1.4.
The 50mm could be announced along with the new EF 24-70mm f/4L, which is also said to have image stabilization.
