I am considering purchase of the 400m 2.8 IS. The longest lens I
currently own is 70-200m 2.8 IS with 2x. I would appreciated
comments from those who own the 400m on image quality, problems
with its weight/size, happiness with value for $$ etc.

I picked this lens because it's the longest focal length with f/2.8
and very versatile. It's 560/f4 w/1.4x TC, 800/f5.6 w/2x TC, and
yet AF w/1D at 1120/f8 with stacked TCs. Yes, it's heavy, but
mounted on the Wimberley gimbal head, you don't feel a thing. I'm
glad I made the right choice.
