I'm telling you there has never been a time like this before. So many cameras coming our way.
Well, actually there have been times like this, and even more so. In the 1940s the patents (DRP) on the German cameras were all declared void and anyone could copy them. That set off a worldwide explosion of camera making in the U.S., Russia, Britain, Japan, and even Italy! The Nikon S rangefinder was a modified Leica and that evolved into the Nikon F in 1959, which set off yet another round in the 1960s! The invention of roll film by Eastman Kodak set off two waves of small camera innovation: one around 1900 and another in the 1920s. It was during this period that photography came to the masses and instead of having just three or four manufacturers the technology spawned hundreds! Once major brands now forgotten include Gundlach, Ensign, Ross, Voigtlander , ICA, Ikon, Century Camera Co., Conley, Seneca, Wollensak, Ansco, Premo, Ferrania, Thornton Pickard, Erneman, Welta, Foth, Certo, Plaubel, LEICA, Franke & Heidecke (Rolleiflex), Leica Wetzlar, and dozens more I can't remember off the top of my head. So I'd say that period was clearly far more reaching than what we have at the moment. And, I don't think the cameras will prove to be the significant thing in the long run--they're all very similar. I think that will be the new lens mounts. As you can see, there have been "break outs" of technology throughout photo history that are not only similar to today, but exceeded it.
