Hello im currently running two xti's with bg-e3 grips. there great little bodys but its time to upgrade. Im undicided between a 1d mkii n or 40d. I know there two completely different worlds. I try to shoot sports but i hardly get that "shot" because of the 3fps on the xti. I used a friends 40d and that seems to get the job done i like the feel in the hands and a lot of new features compared to the xti or the 1d mkii n. I dont know which way to go older pro or newer semi pro?? please helppp
