If you are a photographer, definitely you use cameras. It’s obvious.
Thing is that every year you have newer cameras on a market with new features. Some of them you need for sure, like ISO, focus system, color depth, and some reaches you don’t care about.

If you work on a market, you will have requirements about equipment that you use, Basically, clients want to print photos on billboards, or crop them after. Mainly you will need a high-resolution camera with a digital back like Phase One. These cameras cost a lot. But you don’t need to buy it. All professionals rent cameras specifically for projects.
