A newbie here but have been taking photos for a while now. I have been using my trusty 5d classic with a couple of L zoom lenses (24-70, 17-40). I shoot different things from food to landscape, architecture and street, purely hobbyist level. I have been trying to make the most of what I can do with my camera however, some of the limitations gets in the way, mostly the ISO. Looking to upgrade to a 5dII or III but wanted to get your thoughts before pulling the trigger.
