I'm not sure if this is in the write forum or not, so if not, please bare wit me. I am considering upgrading from my sony h7 point and shot to a mid level dslr. Currently i shoot mostly low light family photos and sports in dimly lit arenas. This brings two questions
1. will i notice that large of a difference in low light, no flash pictures, due to the larger sensor.
2. for when i am shooting sports, how much quicker can i expect the auto focus between my current camera, and say a nikon d80?
Thanks in advance for you comments
