Haha Mike, to be honest I'm thinking of trading my Canon 100mm f2.8 macro for the new Canon 100mm f2.8L macro. Since I've gone full frame I'm not using the macro lens for other purposes as macro anymore. My 24-105 takes a beautiful photo at 100mm f4 as well and it gives me the advantage of flexibility, weathersealing and IS. And if I want to shoot a shallow depth of field portrait I'd rather pick my Sigma 50mm 1.4. Therefor the 100mm stays in the bag quite too often.


I'm thinking the weather-sealing and image stabilization of the new 100mm L could come in handy for me so I'll use it more often(and also make my macrophotos better), but I'm not entirely convinced yet and I was looking at other things to spend my money on and at that point I began stretching my budget looking at the 135mm f2L, the MP-E 65MM macro(don't think my 430 flash will cope with this one) and some others [:P]
