AHHHHH. New Lens...

Since I know very little about cameras, I judge lenses by their size. That is a very nice lens.

damn

i wouldn't want that for skiing, but it's a sick setup

I would do horrible things for that whole setup...

Yea, its pretty sick.  Im just testing it for now, shooting it for the weekend to see if I want to pick it up.  I will see what happens.  The only issue that i am seeing is overlap with the 70-200 2.8 I have my eye on...

...Granted, I would be using them for totally different things,  the 2.8 grey bird days in the park and trees, and the 100-400 blue bird in open situations down in Argentina.  So there is a spot for both.  its just a matter of dropping more money on them.

Both fit in great the EFS 18-135 IS the 7d comes with.  Just need to add a fisheye and a few primes, and I will have the Canon kit set up, and no more Minolta/Sony glass.

i'd like the 100-400 for serious big mountain shooting but i'd find it somewhat limiting in other situations. i'm happy with the 70-200 f/4, it's light, sharp, and has a good range

Get the 70-200 2.8. I have one, you won't regret it.

dope lens son, like you said, it would be PERFECT for your stuff down in argentina.
