Preach it. Shooting on an interchangeable lens camera is still effectively like shooting a film camera.

They do have software to pair to your phone. I am most familiar with Fuji’s solution for that, which is, to put it charitably, execrable. It is painfully slow and glitchy. (I’ve heard better things about Nikon’s latest, but I haven’t used it.)

Thing is: I think that would require a partnership with Apple or Google, or perhaps Samsung. I think you’d need a lower-level API for very quick pairing and a smart handoff to a low-power mode that doesn’t suck your camera battery dry over the course of about 4 hours.
