I am now in need to buy some fast glass, I have a couple wedding booked for next summer and i am doing outdoor portrait pretty much every weekend (i am booked for the next 5 weeks). I am kinda stock between the 17-55mm 2.8 and the 24-70 2.8. since i am shooting mostly my 50mm 1.8. Im kinda comfortable shooting in that range. i did read the reviews they are clearly really nice lens. the 24-70 is kinda a little bit over my budjet but i think it would be a great investement since i plan on going with full frame camera in the future. now i was wondering if anyone had the chance to shoot weddings with both and wich one worked best? i am also considering the sigma 70-200 2.8 since the nikon vrii us outof my price range...any one shooting with the 70-200?
