    The Tamron 10-50 mm could be the most interesting product since the beginning of the digital age.
    A 15-75 mm equivalent lens in APSC is a dream. I´d like to see good IQ along the range, but not sure if a 5x zoom is too much. Maybe some clever camera makers could also launch compact big sensor cameras or wide zoom lenses for mirrorless cameras covering this extremely useful range or at least a 20-60 mm equivalent, 3x zoom in APSC or 4/3 formats.

    • BP2012

      Fisheye with short telephoto range? Very unique indeed. I thought that Pentax 10-17mm fisheye zoom is unique, but this is really two steps beyond. I hope it won’t be good only on wide end.

      • Zos Xavius

        Quite honestly I think FEs have very limited use cases. It would likely show heavy distortion even at 20mm.

        • Grateful

          Thanks, always appreciate the lessons.

          • Zos Xavius

            You must be a lot of fun at parties.

    • Ken your friend

      Agreed. Give it to me X-mounted please!

      • Sky

        It’s clearly a DSLR lens, not one for mirrorless (and: no, Tamron isn’t Samyang). There’s no market on X-mount (or even: X and E-mount combined) for Fuji to justify development of such an unique lens.

  • “Konica Minolta filed a patent for a … medium format lens.”

    Ok that’s odd.

    • BdV

      You mean because their camera business went to Sony? And as far as I know their lens developers went there too? Yes, that’s odd, but this is not the first time it’s mentioned they were actually developing lenses. Maybe a few of the lens designers stayed at KM. I remember they were also developing a wide angle zoom, and one or two more lenses, for M43. I wonder if maybe those products end(ed) up as tamron / panasonic / olympus products.

      • Thom Hogan

        Konica Minolta retained quite a bit of the optical team because optics are still important in many things they do. In reality, KM has been making a few lenses for others (mostly Sony) for awhile now.

        • Sky

          KM has been making lenses mostly for JVC since Sony took over A-mount and engineers responsible for designing lenses for a larger sensors.

    • Probably for the upcoming Sony 8K system. Video most likely.

      • Sky

        Very unlikely.

  • Sports

    The Velbon switchable aspect tripod head looks like a really clever solution. It has two stable positions, and no need for tightening screws or other kinds of locks, it seems. It’ll take no time to switch. But it won’t work if made of plastic or weak metal.

    Does something similar exist already? (I don’t know much about that kind of gear.)

    • Ken Elliott

      I’d be more concerned about how the pivots are constructed. Any slop there is magnified at the camera. I’ll stick with an L-plate and an Arca-Swiss ball head, for now. Simple and extremely rigid.

  • worldcup1982

    Isnt fuji the only one with 2/3 sensors right now? i wonder who would be the manufacter to provide these sensor to ricoh…

  • MonkeySpanner

    I like the panny 35-100 f/4. Mimics the classic 70-200 f/4 – nice. I hope it is high quality.
