Newcomer SLR recommendation. I have used SLR, know a little about photography, know PS, and want to make all kinds of films. Machine for advice?

What's the budget for the full-width machine? Are you going to spend three yuan? Canon and Nikon can do it. Which brand do you like? Without these two high-end models, the difference would be subtle. Depends on which brand you like. Quality and performance are evenly matched. At present, Canon 5d3 is used in most photo studios, and Nikon is less, because the lens resolution is harder and Nikon is softer. Canon is the product landscape, and Nikon is the portrait.
