A few days ago, Ricoh filed a patent application in Japan for three new full-frame telephoto lenses, one of which is for mirrorless cameras. These aren’t the first they’ve filed, either, having filed patents for a couple of other mirrorless lenses a month ago. Could this be a turning point for Pentax, the one company that’s been holding onto DSLRs for dear life while the rest of the world goes mirrorless?
The three new lenses described by the patent aren’t particularly high end. They’re all variable aperture, although the one for mirrorless has a max variable aperture of f/2.8-4, so not too terrible. It’s doubtful, though that Pentax is planning to pursue the mirrorless market. At least, not yet.
