I just got into photography and enjoy taking pictures of the basketball games at my old high school. I have a Canon t2i. Right now, it is tough to get decent pictures because I use such a high ISO with my kit lens and the 55-250mm lens. I have been looking at getting the 50mm f/1.4 lens for shooting in the low light. However, I talked to a pro photographer who takes a lot of pictures with me and he recommended I get a lens like his. I think it was 80mm and i know it was an f/2.8. I found the Canon 85mm f/1.8 for almost the same price as the 50mm f/1.4. Which would you recommend for shooting pictures in a gym? Also decent auto focus and quality is a factor as well as aperture and the ability to let light in. I'm always right at the sidelines and under the basket so that could be a factor as well. Any input will be helpful is my future purchase! Thanks!
