Since i'm not a pro photographer, i don't take much equipmenet with me. Only camera and maybe a flash. Sometimes i'm shooting my friends in really hard conditions. When i was on 5dmk2 is was pain in the ass to shoot even on 6400 iso. But now, with 6d, i can capture even on 25 600 without problem.

Maybe there is a was to make them better? Especially first one.
