To me, the SLR has always seemed like a somewhat inelegant design that nevertheless solved real problems present in rangefinders (and other non-reflex cameras).

To me, the SLR has always seemed like a somewhat inelegant design that nevertheless solved real problems present in rangefinders (and other non-reflex cameras). The whole idea of a big, heavy, loud, flappy mirror mechanism just seems clunky on some level. Mirrorless digital cameras get to solve the same problems in a much simpler, more elegant fashion, and the day I got my first mirrorless camera, I knew I'd never buy another DSLR.
