seriously have a look at the sigma 85 f1.4
at f2 to f2.8 it is super sharp, blows away even the 70-200 mk2
"Blows away"? Wombat, you been smoking powdered KR rolled in DxOMark papers again?
That would bei THE idea! Someone should tell Canon to add a little bit of LE or angel dust into their rubber grips. The we would all be a little bit more happy and satisfied ba the product Canon sells.
It makes happy, believe.
The Canon 100mm 2.8 is an good lens (850€ L, non L half of it) . Sigma EX 1.4 85mm DG HSM too (1000€). Don´t forget about the Canon 2.8 60mm (450€)or the Sigma EX 2.8 50mm DG (360€).
Maybe you try one of the cheaper macros. So you get "two for one" (macro too).
If you take the Macros, the filter diameter is quite smaller. So the filters are cheaper - if you want to to do so.
