the last SLR holdout

Mirrorless cameras are officially taking over; everybody wants the slim camera bodies and short lens registry distances that are made possible by electronic viewfinders. Nikon has come out with a new Z mount and almost simultaneously, Canon has come out with a new RF mount (which looks to me like it will be a real “RF” of people who bought into their smaller and older EOS-M system, as it is not at all compatible, and it might not even be possible to make an adapter to mate them). Meanwhile, in the medium-format world, Hasselblad also came out with a mirrorless camera sporting a new short-flange lens mount a while ago — I think they call it XCD — and Phase One put together a mirrorless bodge setup branded as Alpa, which must have something that counts as a lens mount. This means that almost every camera company that didn’t already have a short mirrorless lens mount (Sony, Fujifilm, Olympus, Panasonic, Leica, and formerly Samsung) has now added one to their product line. As far as I can see, there is only one holdout which still offers only a long-flange lens mount and traditional SLR cameras: Pentax. As it happens, I’ve got Pentax.

Does this mean that Pentax needs to do a me-too and come up with their own short mount, to keep up? It does not. There are lots of reasons why it might make perfect sense to offer a mirrorless camera without changing the mount. They’ve already updated their existing mount so it can operate in a fully electronic fashion with no legacy mechanical linkages. Lenses made for mirrorless use can still have their back end close to the sensor; they’ll just have the mounting flange further forward, with some of the glass hiding inside the body of the camera. This will create a pancake-like appearance for lenses that are not actually thin. Another possibility is that filters can be placed into the gap. Or the protruding barrel can be a place to mount a control ring. I think it’s a perfectly viable way to do mirrorless, though for some it won’t win aesthetic points.
