New SVG teleconverters

Sigma has released compatibility information for the soon-to-be-released TC-1401 and TC-2001 teleconverters. The main points are:

  • The new TCs will not be compatible with any pre-Global Vision lens.
  • They will be compatible with the following Global Vision lenses: 120-300mm f/2.8 Sports, 150-600mm f/5-6.3 Sports and 150-600mm f/5-6.3 Contemporary.
  • Enabling compatibility with the 120-300mm f/2.8 Sports requires a firmware update of the lens via the USB Dock, or by sending it to Sigma. The update is set for release on October 24th.

A compatibility table was also published:

    When I went with the 120-300 S, I was really hoping they would release newer teleconverters meant for high megapixel cameras and they delivered. It is a bummer about backwards compatibility and having to have the usb dock to use them but the dock was one of the selling points of the lens line. I will definitely be getting one to see how it performs.

      A lens is a set of optics desighned to work with a camera…I see no use for a dockingvstation and complicated programing just to put a lens on my camera.
      If this docking station provides some feature beneficial to someone I dont care as long as I dont have to use it…but if I need to use it to work the lens then I dont need the lenses.
      It was bad enough I had to biy a proprietary set of TCs jist for my Sigma lenses…but now they expect me to buy a different set of proprietary TCs for each sigma lens I own plus a proprietary docking system and learn how to use it just for the priveledge of using Sigma lenses.
      I was really excited about thes new sigma 150-600 lenses…then they made 2 different ones and will not make the one I want for Sony..and now they further complicate it.
      I want the Sigma lens but there is a limit to how far I will go to get one.

        Do you have a 120-300 S?

        • animalsbybarry

          I primarily use long lenses and macros.
          I have Tamron 60,90 180 macros
          Sigma 70-300apo macro
          And am planning to get one of the new 150-600s..but have not decided which one yet.
          The 120-300 does not have good close focusing therefore I did not buy one.

          • Russell Ferris

            The close focusing on the 120-300 S is strange, it breathes throughout the entire range but it does focus good and close at the 280mm marker on the zoom ring. The USB dock was a cost factored in with the lens and so were the costs of updated teleconverters, glass isn’t cheap.

    Will the new global vision lenses at least be compatable with the older Sigma Apo teleconverters?

    • Florent – SigmaRumors

      I asked Sigma. Here’s what they say:

      The converters will work allowing the features they were designed for but not the features of the new converters. Autofocus would be limited to an f/stop of 5.6 or faster when the converter and lens are together.

  • animalsbybarry

    I find this VERY disturbing.
    First we had to buy special apo teleconverters just for our sigma lenses because omly they were compatable with the Sigma lenses and nothing else…
    Now we meed to buy NEW teleconverters to be compayable only with the NEW Sigma lenses and nothing else…but on top of that we have to program it with a complicated docking system that I have no idea how to opperate before they will even become usable.
    Its way over the top and totally unnaceptable.

      I’m sticking with my previous-generation 120-300 f/2.8 for now. According to the lensrentals blog’s tests and dissection of both lenses (as well as the lens element diagrams from Sigma), the new “sports” version has the name optics and innards as the previous “OS” version. You get some new features (focus limiter, dock compatibility, different case) but that’s about it.
      What I’d really like to see is a comparison:
      previous generation 120-300 “os” with previous generation teleconverters
      current generation 120-300 “sports” with the new teleconverters
      … to see if the TC optics actually improve, or if they just have new elecontronics.

      • animalsbybarry

        To make a proprietary tc is bad enough…but to then come out with a new proprietary tc and no backwards compatability is outrageous.
        The only thing that matters is optics…to cripple that with proprietary incompatable electronics is…..I cant even come up with words for it.
        The Tamron 150-600 is starting to look better to me right now.

          FYI, The Tamron is not compatible with Canon mkIII TCs

          • animalsbybarry

            Tamron is not compatable with any tc except Kenko.

          • Pierre

            It’s not even compatible with Kenko…

          • Bokeh

            It is perfectly compatibe with my Tamron TC1,4SP. On my D800 AF in live-view is perfect from f9-13.

      you dont have to buy the docking station. Send the lens in to Sigma and they will add the update needed. There is nothing complicated. It’s just as hard as putting a message on this board 😉

      • animalsbybarry

        So I either have to buy a docking system I have no use for and figure out how to use it…or buy a lens and then ship it back to Sigma and wait for them to ship it back…plus I need one set of tcs for my new Sigma lenses plus another set of tcs for my old Sigma lenses, plus a different set of teleconverters for my other lenses…all of which I need to carry on location and instany ..correctly…choose the corect one to use in the field.
        All while hoping my subjects dont see me and run away.
        I didn’t realize it was so simple.
