CameraSize.com and apotelyt added the new Zeiss ZX1 to their comparison tool and it’s a very large camera. Apotelyt has Front/Top/Back view, while camera size only has front and back. I think camerasize.com is a little more accurate with their sizing, but since both have their comparison tools ready I decided to post both together.
