Well, there's a 6D and a smartphone running EOS remote... but it's unwieldy if you're holding both of them.Yeah...not to mention you lose the 1000-shot battery life advantage of having a DSLR.
I wonder... you will be using your wifi, but on the other hand your screen and its illumination will be off instead of on. I wonder which uses more energy and which contributes more heat and electrical noise inside the camera?
I like the thought that the screen on my 60D keeps the display hardware outside the body when I'm doing long exposure astro photos.
And speaking of weather sealing... what about the microphone holes?
what about the main dial behind the shutter button!
