I'm asking myself the question. If I were to design a digital camera what sensor aspect ratio would I choose? Leaving aside the questions of sensor size and number of pixels what is the "ideal" aspect ratio? 35mm is 2x3 Large format is 4x5 Television sets (and most computer screens) are 3x4 Hasselblad and some other medium format cameras are 1x1. My personal preference would be for 1x1. It gets the most out of the lens and I'm probably going to crop anyway. What say you?
