I've been receiving a lot of stuff recently, most of which I'm figured to be fakes. Like the 5D Mark III commercial. I've also received a lot of camera specs based on the patent from a few days ago.
However, a decent source that's correct about 50% of the time sent me information about upcoming lenses from Canon.
I'm told an EF 14-24 f/2.8L and EF 24-70 f/2.8L II will be announced at the same time. Whether that's with a new 1Ds or 5D Mark III was unknown. However, Q4, 2011 or Q1, 2012 was the timetable.
CR's Take
Patents for both optical formulas exist, so it's highly possible. I have a hard time seeing Canon adding to the L lineup until the 8-15 starts shipping.
EF 200-400 f/4L IS 1.4X
We can expect this lens to become an official product with an announcement this fall. Availability in late Q1 2012 I'm told.
