The year of the lens?
We mentioned previously Canon may have a “record year” for lens announcements in 2012. Below are more suggestions and info about new lenses.
EF 35 f/1.4L II
Suggested announcement in April/May 2012. Expect the cost to be high.
EF 100-400 f/4-5.6L IS
300 f/4L IS
400 f/4L IS
Suggested announcement in the fall. Perhaps showing for Photokina? A replacement to the EF 400 f/5.6 could realistically come in the shape of a new, and much better EF 100-400L IS. A 400 f/4L IS could fit nicely between the 100-400 and 200-400 (which is going to be very expensive). The built in teleconverter on the 200-400 is going to be a big feature to a lot of photographers and will help justify the cost. I don't think the 300 f/4L IS needs replacement, but it may be a matter of easy manufacturing to do a 300 and 400 at the same time.
EF135 f/1.8 IS
It was suggested that this lens exists, but has been “shelved” for the time being. This seems odd considering the new EF 24-70 f/2.8L II didn't get IS.
The new lens madness may continue into 2013.
