Ok, one very first impression after finally taking the 6D out with me for some more extensive time, is that it gave to my 24-70mm lens (yes, Mark, the one I got from you, still a favorite of mine) a whole new meaning. 24mm is a real "wide angle" focal length, while 70mm is still a nice zoom. Quite obvious for many here, but I just thought I'd mention it.

I am probably going to miss the zooming capability of the 70-300mm, but I have not really used it extensively since I have the 6D to tell.
