Hello,


I don't own the 135mm, but the 100 mm f/2.8 L macro IS is a stunning lense for macro, portrait, street photography and even close sport (that's how I use it anyway).


What's more, the IS is very efficient (new Canon stab is great), and it's, well, absolutely sharp.


This lense impressed me much than the 70-200 f2.8 (maybe because there were less expectations, but it rarely leaves my 7D)


Ok, it's less versatile than the 24-105 (or any zoom) but that's another problem.
