My son is competitive in taekwondo and there are always some great action shots to be had. I currently have a T2i with kit 18-55, kit 55-250 and a nifty fifty 1.8.
The nifty fifty is best for these indoor tournament lighting woes but is too slow in focusing. Using back button focusing is helpful but still not ideal.
What lens would be a better choice? I can't afford a canon 17-55 f2.8 but a sigma or tamron is affordable. Most shots I am close but going to 85 or more would be better. Just need something fast and good in low lighting.
