Camera body frame rate and autofocusing
If you like taking action shots then you will be frustrated if the camera’s frame rate is slower than 6 shots per second – around 10 per second would be ideal. Also, the camera’s ability to autofocus quickly will be significant if, for example, you want to take birds in flight; both the camera and the lens play crucial roles in this function. Take reviews you read with a pinch of salt and try the various combinations yourself before making a purchase.
