I'm in the crossroad of selecting my main lens for wedding photography job.
At the present, my Canon 17-40 F4 working with my 5Dmk2 as main camera on the wedding assignments, and the 50D as backup pair with 50mm(80mm in FF) or 85mm(135mm in FF) it depend on the environments. Work under high speed (ISO 1600-3200) almost the standard, that's why I need the 5Dmk2 to hold the noise.
I'm thinking of adding on a mid-range zoom, and in the cross road between Canon 24-70 F2.8 or 24-105 F4, I don't know which lens IQ is better, I'll shoot with full open most of the time.
Please share your actual experience with these lenses in order to help me decide on one of them.
Thank you
Paul
