When it comes to sheer power and resolution, medium format backs still sit at the top of the heap and Mamiya Leaf has a new option today. The Credo line comes in three options, 40, 60, and 80 megapixels. Except for the sensors the models are extremely similar. The back of each back has a 1.15 megapixel, multi-touch screen, which is more like what you'll find on a smartphone than a typical touchscreen camera. The touch-sensitive area actually extends beyond the image viewing area, which gives the graphic interface more flexibility.
