I think Canon isunder pressure to make a 24-70 IS. However, there are a couple of lenses also probably higher on their hitlist:


35mm f/1.8 - to counteract Nikon


200-400mm f/4 - Nikon's awesome lens has no other counterpart. Canon could produce one of these, narrowing the gap in their wildlife lens range. More $$$ than the 100-400 but less $$$ than the 500 f/4. Maybe $4000. nice.


180mm f/3.5 - Canon's ultimate macro lens is slow and beginning to show its age.


200mm f/2.8 prime - very old.


135mm f/2 prime - a great lens that needs replacement with IS.


I personally would go bananas for a Canon 200-400. It could be a killer lens for FF and APS-C. Then again, the 24-70 would probably make a bigger impact than any of the lenses above. The only thing is that Canon introduced it fairly recently (2002?).
