whats up guys, I'm looking into a new camera and I'm in a bit of a pickle. i cant decide on wether a 7D or a 5D mark II. Which is better? I can buy the 7D and save some cash but I really need good quality and detail in low light. I plan on buying a 24-70mm 2.8 L lens for whichever body i choose. Im going to be shooting mainly portraits so im going to need a great amount of detail. Will there be a significant difference in quality of the photos between the two? Personally I'd rather buy the 7D to save some cash but i need top notch photos and the Mark II has great reviews. Help? thanks guys.
