As the title states I will be renting a 5d mrk III for an upcoming dance recital. Before I drop 3k to upgrade from my 7d I want to make sure it will perform like I believe it will. My question now becomes one of post production. Will my LR 4 and photoshop elements 11 support the 5d mrk III files or will I need to upgrade to LR 5 and a newer more advanced PS? I had a friend upgrade to a full frame Nikon and his LR and PS version didn't work. He had to buy the latest version of LR and photoshop. Thanks in advance. BTW..I will be shooting RAW.
