>>3790313>Although given that mirror less bodies come really small and include all of those things>all of those thingsAre you kidding right now? Mirrorless bodies don't have the mirror or its mechanisms, pentaprism, usually no built in flash. No mirror or its mechanism means things it does have in common with a DSLR can be put where the mirror mechanism would be. No mirror means flange to sensor distance can be made smaller because the mirror angle must be 45° and its dimensions are dictated by the size of the sensor, increasing depth of the body. EVF is a lot more compact than a pentaprism, no flash means no big capacitor, bulb or reflector/optics. If you made a DSLR with the exact parts that came out of this a7 you'd have to add a pentaprism in place of the EVF, a mirror, its mechanism, its motor, and an AF sensor array. Adding the mirror will make the distance from flange to sensor larger, adding the pentaprism will make the camera taller, adding the motor and mechanism will displace other components outward and make the camera thicker or wider, etc.
