my ideal camera would be a full frame sensor mirrorless. Weather sealed against rain and dust. With a good trio of fixed lenses. Best would be a 21mm f2.8,45mm f1.4, and 90mm f2. Or there abouts. A good evf or ovf is a must, as is manual focus on the lens that isn't focus by wire with distance indicators, aperature on the lens as well, and a shutter speed dial on the camera so settings can be done with the camera off.
