Pour 2013 non ????? :
Lenses
4 new EF lenses will be launched in 2013, there was no mention of exactly which lenses it would be. We all know the usual suspects, and everything points to a new 100-400L and that would sit nicely next to a new 7D.

400mm Everywhere!
I have received various bits of info over the last few months about Canon’s plans in the 400mm range. There is lots of desire for a new 400 f/5.6L and 100-400, and both may finally be getting an update. It feels like the 100-400 has been in the update cycle forever, but judging by how many of these things Canon sells, I can see why they’ve been in no rush to have it replaced.

Below are lenses that are apparently in prototype form and are on tap to be announced in 2013.
■EF 400 f/5.6L IS (Highly desired)
■EF 400 f/4L IS (Not DO)
■EF 100-400 f/4-5.6L IS (Not push-pull & patents exists)
■EF 200-400 f/4L IS 1.4x (Long known about)

We were recently told that a new EF 100-400 f/4-5.6L IS was coming sooner than we originally thought
