The next 35mm…
The oft rumored EF 35 f/1.4L II is being talked about again. We're told an announcement for the new “L” prime will only happen once the new EF 24-70 f/2.8L II begun shipping in decent quantity.
That would put the announcement sometime in 2012 with availability probably being in early 2013. One patent for the optical forumla has been around for a while.
I'm told as many as 3 prototypes exist, though they have only made it to a very select few photographers.
I'm pretty confident this lens will be announced sooner than later, and I wouldn't be surprised to see it paired with a new high megapixel camera.
