I have shot high school sports with the 7D since 2011 and am interested in upgrading my camera body to the 7DII. I am wondering about the "lowlight" improvement over the original 7D. I have friends that own the Mark II but never shot with the original 7D. How are the noise levels at higher ISO's with the MarkII? I know full frame offers huge improvements in this area but I really don't want to make that change for various reasons.
Any input will be appreciated!
