I have a Canon Rebel t3. I am interested in sports photography and would love to get a better lens. I'm not really up to par on tech specs or anything. I've had my camera about 5 years and mainly shoot things on sports mode; I don't get into messing with the manual settings because I don't want to miss my shot. I am looking at this lens. What do you guys think? Do you think this will suffice my needs? I have been reading reviews and looking up information.
