Right now I have 2someone 5d classics. Looking to upgrade 1 to a mk2. Would it be smart to keep the other 5d or should I get a 7d. I shoot weddings, portraits, and cars. I know alot of ppl have mixed reviews but what would be best? I was thinking of leaving my 70-200car 2.8 is on the 7d5d for the extra reach but idk. Im doing the upgrade to get into video. That's why the mk2 I deff am doing.
