What's in the pipeline?
A few more confirmations about a new EF 800 f/5.6L IS II being in the works. It was stressed that it is no where near market ready and Canon will probably wait for Nikon to get their new 800 to the world. The EF 200 f/2L IS is also on the update radar, but is for the distant future.
Another source claims to have tested a new “Canon ultra-wide zoom on an EOS-1D Xs”.
A New 135L?
We have received lots of information over the last few years about a replacement to the EF 135 f/2L. It reminds me of the EF 24-70 f/2.8L II, which turned out to have a lot of prototypes before it was released and caused me a lot of headaches :). The current tested prototype is said to be an EF 135 f/2L IS. A replacement seems imminent, although I'm not sure if the IS version will ever make it to market.
When is the new stuff coming?
I'm told that current NDA's expire at the “end of the month”. I hope to know more soon in regards to announcement date(s), there is definitely more coming in 2012.
