Nope, wrong. SLR is defined by a single lens AND the presence of a mirror and a prism as apart for example from mirrorless, single lens rangefinders or view cameras. SLR is one of many camera designs, and even though I'm not a purist, I would like if the paradigm stayed the same - this has nothing to do with LCD displays, electronics, digital sensors or film. I like how they work, and that's why I use them. I don't need a live preview, I don't need a movie mode, those things may be useful to some but why would anyone force them into a reflex camera, and essentially cripple it, is beyond me.
