Canon announced all sorts of crazy shit pre-photokina:
EOS 60D: expected, and pretty cool. 9/10ths a 7D for a lot less.
EF 70-300mm f/4.5-5.6L IS USM
EF 300mm f/2.8L IS II USM
EF 400mm f/2.8L IS II USM
Extender EF 1.4x III and Extender EF 2x III: *yawn*
EF 8-15mm f/4L Fisheye USM: WAT. My favorite response to this was Mike @ ToP: "because they're Canon, and they can"
The 300mm and 400mm F/2.8Ls are replacing models that were introduced in the late 90s. They'll be fantastically well made, boat-anchor heavy, and even more eye-wateringly expensive. The 300mm's MSRP is $7000, the 400mm's is $11,000.
I dunno about an L-grade version of the 70-300mm. It's gonna be F/5.6 for most of its zoom range, and with an MSRP of $1500, I wonder who is the intended market for this beast.
I am quite sure that no one (No. One.) needs a circular fisheye zoom, especially for $1400, but it's pretty fricken cool that Canon made one.
If that weren't enough, Canon announced a new tiny prototype sensor: Canon develops world's largest CMOS sensor, shoots 60fps video in moonlight
