Hello! I have been shooting at a few local rodeo and rough stock events in our area. At the end of November I get to photograph a rodeo school and am needing some help in regards of what lens I should use. I have a Canon EOS Rebel T3. I have the 18-55mm lens that it came with, as well as a 75-300mm lens. While they both can get the job done, I'm really not a big fan of either and am sure there is something else out there I could use. Hoping to rent a lens and play around with some before I buy one. Any advice? I shoot mainly outdoor arenas, and the school will be outdoor, so the lighting is much better than indoor, obviously. I'm a newbie at this, so I'm still getting used to all the functions. That could also be something I need to do, adjust with the lenses that I have. Any and all advice is VERY welcomed!
