Hi, I'm about to begin apprenticing as a wedding photographer. I need to upgrade my gear for better performance in low-light situations. I currently shoot an old Canon 7d Mk 1 with a 50mm 1.4 prime lens.
With my budget the options I have are to either upgrade my camera body to a new 6d (and shoot with the same glass) or to purchase a used EF 24-70L for use with my 7d. Which would give me the most improvement in low-light situations?
deeply appreciate any help, thanks in advance
