Hysterical -- the pancake lens on a 1dx. I bet you don't find too many of those in the field.
Oh, I dunno. I'm looking forward to the combo - since it's basically no deeper than the body, it'll fit in a Lowepro S&F Utility Bag 100 AW, which will fit in the outer pocket of my computer satchel - likely I'll bring it along on overnight trips whereas otherwise it would be the S100 only. Also, it'll pair nicely with the 70-200/2.8 IS II when the latter is a little long - bringing the pancake is like having a second lens without really carrying a second lens!
Just got my B/H tracking number
Congrats!! Can I ask...what was your order number (as in 1019###xx for web orders)?
