I would like to see a new innovation from Sony. Abandon 36x24mm sensors in favor of 35x28mm sensors. 20% more area, yet more compatible with all current 35mm format full frame lenses. No need for expensive medium format. If people desire 36x24mm format for video, cropping to 35x24mm still provides a format very close to 36x24mm with less than 3% fewer pixels than 36x24. The 35x28 format (5x4) is a much better portrait format. What do you think, Sony?
