Canon 400mm f5.6 L lens - upgrade needed.

I don't see an upgrade of the 400mm F5.6 ever being made in its current form. It's always been a direct competitor to the 100-400 and with a rumored upgrade for this without the push pull zoom it makes no sense to upgade in its current format.

Perhaps they will introduce an 400 F4 (recent patent) which would sit below the 200-400 and 400 DO? I could see 400 F4 being a nice upgarde for APS-C cameras for wildlife photographers which will give equivalent framing of 560mm with a 1.4x tc with working AF.

I think Canon needs a lens in the class of the 14-28 f/2.8 Nikkor before they update the 400. Ultrawide zooms are their sole remaining lens weakness vs. Nikon. They've been updating their wides with world class upgrades (17mm and 24mm TS-E, 24mm f/1.4L II), so we know they can make a killer wide angle. Now they just need to upgrade the 17-40L and 16-35L to something that's sharp from corner to corner.

And yeah, an IS version of the 400 f/5.6L is going to be close to $2,000, I think.
