The perfect camera for reportage photography! if you are short on 1D :) in AI SERVO mode, practically without losing f/s, it focuses on what you want :) with a long recording, the form heats up and cuts down the recording . but this is in a hot room and at a high ISO value there is not enough sport mode when you need to shoot something quickly, and when you donβt care about quality, but there are 3 customizable modes for this :) in general, a wonderful camera if you use it for its intended purpose, and not shoot it in a studio :)
