This is a quote from Cannon's overview "Gleaming white, with a removable tripod collar," so it looks like they won't gig us for another $75 bucks or so to get a collar. The carrying case appears to be one of the pouch's the black Llens use, not the cool zip pouch the 100-400 comes with.

The 100-400L that I had, had a sweet spot around 300-320mm. At 400mm the image wasgood but the images around the 300-320 seemed to always be better. At 100mm the 100-400L was always lacking in my opinion, and the 70-300mm appears that it will beat it easily at that distance. I would be interested in seeing the 100-400L compared to the 70-300 at comparable lengths.


If it is light enough, and compact enough it might have a place with me to just carry around in case an oppritunity presents itself. If it is not easily protable I will always go prime.
