Testing my 70-200L IS

My 70-200L IS arrived yesterday.  It had big shoes to fill since I loved my 80-200L so much, so I decided to see how well the new lens would
stand up to other lenses in my collections with the same focal lengths.  I tested at 135 and 70.

 

Compared below:
Canon EF 70-200 f2.8L IS 
Canon EF 135 f2L 
Canon EF 28-70 f2.8L 
Canon EF 28-105 f3.5-4.5 USM mkI 

Here's the subject:

 

All images are 100% crops, shot with a Canon XT, tripod mounted, large/fine jpeg (reduced to 50% in PS), Custom WB, ISO 400, M mode.  No corrections applied.

Of course the 135L is one stop faster, so I can drop it to f2 and get:
