was wondering if anyone had any experience of shooting with this lens or the 50-250 version in a boxing or similar sport where lowish light levels would be an issue. i have taken still pics at these sort of events but now want to video them without breaking the bank. lighting will be an issue as i will be away from the ring on a stage so. need a cheap zoom lens to couple with my 70d. price wise looking at upto £300
thanks in advance
