The Digital Picture review with it mouse over comparison images is really useful. If you look at those subtle differences and decide the Canon is worth 2x the cost, then by all means, go for it.
Personally, I would buy the Sigma AND a nice used 135mm f/2L for the same money.
I already have the 135L, that's part of my dilemma
