Tamron filed a patent for a new 10-24mm f/3.5-4.5 lens

Tamron filed a patent for what appears to be an update to the current SP AF10-24mm F/3.5-4.5 Di II lens. For comparison, here is the current model:

The interesting part is that Nikon's optical design for the Nikkor AF-S 10-24mm f/3.5-4.5G ED is almost identical:

    agreed. looks identical. good find. maybe this will be a fair bit cheaper. Tamron has some good optics, but from what i felt, more high plastic feel. Good alternative for an ultrawide lens on dx

      NR – where did you get the top image ? The script is Chinese, not Japanese. The language at the top is ‘group’. I don’t know what the language near the front of group 2 means.

      • Thoppa

        Forgot to say – I dunno the second character because it is Japanese I think – so it is a mix of Chinese and Japanese ? Weird.

          it’s Japanese, Kanji looks and reads like Chinese.

    Being a Tamron user, what I feel not is that the why she doesn’t produce some ultra-wide prime or making a model which does not overlap the focal range. 10-17mm might enough as a lot of standard zoom is designed as 18-55mm. Sigma is smarter in this way as she makes 10-20mm f3.5. If I were Tarmon, I prefer to make 8-15mm which is similar to Canon’s for a head to head competition. I really want to see this happens.

      I don’t mind overlap as it avoids having to change lenses too often. Especially when it comes “free”: the 10-24 goes as wide as anything else apart from Sigma’s latest ultra-wide zoom, but goes a little longer than some others. Why complaining in terms of range? In terms of IQ, it does not seem to be as good as the older 11-18, though.

      With regard to Canon’s 8-15 zoom, this is a full-frame fisheye and has nothing to do with the Tamron. The Sigma 8-16mm is a better match, being a DX ultra-wide zoom, but I must admit not being convinced by such an extreme angle of view.

    I read somewhere the Tamron & Nikkor were actually both designed by Tamron but the deal was that Tamron would sell under its brand the slightly simpler and inferior optical design. I don’t know whether it is true but it would explain the optical design of the Nikkor appearing in the Tamron patent.

    AFAIK, there has been precedents of collaboration with Tamron, like the Nikkor 70-300 ED. Pentax and Sony also collaborated with Tamron for their amateur zooms.

      yes, didn’t they have also a similar design in their 70-300mm lenses?

      I thought it was the Sony 11-18mm that was the same design as the Tamron:

        Yes, Sony is Tamron’s second largest shareholder with ~ 11%:

        and some Sony lenses –if not simply re-badged versions– have similar designs to Tamron lenses. But Tamron seems to have associations with other camera makers like Nikon or Fuji (many Finepix models, especially superzoom S-series, have Tamron-made lenses).

    Perhaps both of them have some sort of agreement between them, which is highly possible, taking into account that this is not uncommon among Japanese companies :o

  • benjamin

    the nikkor has 2 extra elements.. and front and back elements are shaped differently.. thats far from identical..

    • look closer

      you were probably seeing the old design of the Tamron. The new one is the one on top of the page. it looks “almost” identical.

      • benjamin

        ah… my bad. thnx =)

  • dv

    What is the benefit of such cooperation?
    Tamron will not produce Nikon mount lens?

    • WoutK89

      its cheaper, cause you outsource the design to another company to do the work for you.
