  • Urgh, does anyone even buy these…

      If one wants to vlog using your new EOS M100 with a 400mm
      lens, what other choice do you have if you can’t afford Canon’s own 400/2.8? 🙂

      • Mistral75

        – Canon EF 400mm f/4 DO IS II USM?
        – Canon EF 400mm f/5.6L USM?

        🙂

        I know you are trying to be funny, but there’s quite a few zooms that cover 400mm, or you can try a digiscoping adapter, or you can get a vintage non-telephoto 400 (Kilfitt, Soligor), or a 2x teleconverter on a 200mm. Lots of options.

    • LeFred

      They’re really small, even compared to DO lenses. They’re ideal for mirrorless cameras.

      Unfortunately, they’re generally designed to be cheap and crappy.
      Yet Tokina knows how to build autofocus and optically stabilized lenses. Too bad they don’t make a modern mirror lens instead of these dinosaurs.

      • Zos Xavius

        How the hell would you put stabilization on a mirror lens? AF? These lenses will remain manual till the end of time surely.

        • LeFred

          AF : Sony / Minolta had autofocus mirror lenses which worked great, but they where designed for SLR cameras, not for mirrorless.
          Stabilization : same as other lenses, with a mobile afocal group in the rear part of the lens, behind the primary mirror.

        • Jeffry De Meyer

          They even do this on the giant space telescopes they put on mountains, so yes it can be done.

      • Tokina knows how to build AF and OS lenses but Fuji does not want to collaborate with third-party manufacturers.

        • Spy Black

          Not familiar with any stabilized Tokinas.

          • Mistral75

            AT-X 70-200mm f/4 FX VCM-S for instance.

    • TurtleCat

      I have heard that people who like to travel with a small kit will use them for long telephoto shots. Probably static shots in daytime where you have plenty of time to focus and plenty of light.

  • Mastenpants

    Hehe your mirrorless camera isn’t mirrorless with one of these..

  • Geoffrey Baker

    But, but…the bokeh!

  • “The lens has no electronic contact.”

    They’re probably the only lens manufacturer which is regressing, not progressing in the feature department.
    Must be why the lens is labelled Kenko, not Tokina.

    • PhilK

      Kenko is the owner of Tokina, the official company name is Kenko Tokina although they still use Tokina by itself in some places.

      I don’t know why they are still producing lenses like these, I thought we escaped the visual torture and inflexibility of these things after their heyday in the 1970s and 1980s.

  • Jeffry De Meyer

    Why are these lenses always so slow?
    Wouldn’t it cost pretty much the same to make them Bucket wide.

    • Spy Black

      They get wide quickly with aperture increase. Samyang has a 500 f/6.3 and it’s fairly wide.

    • Athanasius Kirchner

      Also, the DoF is thin enough as things stand, without aperture control a 400mm f/4 lens is almost unmanageable with manual focus.

      • Jeffry De Meyer

        Depends on how close you are focusing

        • Athanasius Kirchner

          True, but the most common use for these FLs is wildlife, and then it’s limiting. They’re much better for astro or landscape, but then the smaller aperture also works to reduce aberrations.
