  • Wow. 5″. Awesome.


    • no-nikon-no

      this will be a 50-500mm f/4.5-5.6 on the new nikon mirrorless’s midget sensor.

    Seppuku – I don’t know who the one behind this bullcrap, but seppuku maybe what he or she will be doing when this bullcrap fail!!

    let me said this again – FLICK u nikon!!

  • holy

    Nikon is using the mirrorless rumor to boost up their stock value – a way to make more money when they sell themselves to sony or even canon!!

    Nikon in White: It’s a funeral.

  • Disiderio

    So slow!!! Compensating for shitty focus IMO. Can’t criticize it if EVERYTHING is in focus!! Lol

    • Not Surprised

      This is a 10x Zoom — you cant criticize it for being this dark/slow. It is completely normal for such an all-in-one lens. Your comments are ridiculous.

      Clearly Nikon needs pancake lenses and fast primes — but these comments against all-in-one lenses being too slow are just trolling comment.

      • preston

        We can criticize it for being too large though. As for as I can tell the ONLY reason to have a smaller sensor than m4/3 is to allow for smaller lenses. This lens (at least in the dimensions given in the patent) is longer at 5″ than the FX equivalent 28-300mm, which is 4.5″ long.

        Luckily the patent is for the optical design and not the size of the lens, so the dimensions could easily be much smaller in the final product. Just makes you wonder when they give the length in the patent to the thousandth of a millimeter. .

        • BornOptimist

          The length given in the patent is not the length of the lens, but the length from the sensor plane, so depending on the flange distance, which is rumored to be 18mm, this lens is ca 110 mm.

    a great lens for video on the new cam – the zoom range & dimensions are very good. Compare this to a 300mm lens on a FX cam – this is small and allows your using it with ease – question is however: what does the VR offer here?

    • Mark

      People want HDSLR video to get shallow DOF, among other reasons. And yes, i am aware this isnt a dslr. But this lens is not for that.

      • FM2Fan

        But what is the problem? you can change is and use the pancake for close up …

        • Mark

          The problem is everything will be in focus. Just like coolpix video. It will be good for travel and family gatherings, but nothing really serious. And even with the pancake, even if it’s TACK sharp at 10mm wide open, which I doubt it will be, that’s still not all that shallow given the crop factor. Unless we’re given a lens of something like 17mm and 30mm f/1.4 or similar, video is going to be not-so-great in terms of artistic capability. Up close isn’t the problem. The problem is the lack of shallow depth of field capability. The given pancake lens is only a 27mm equivalent.

    The lens looks quite interesting, but too bad it doesn’t have a bigger aperture, at least by one stop.

    • BornOptimist

      This is after all a 10x zoom lens. So that doesn’t bother me much.
      I’m more interrested to know the aperture on the other 30-110 zoom lens.
      This is a 3x lens, and will hopefully be a faster one.

      Hopefully the 14mm f/2.8, 18mm f/1.4, and 32mm f/1.2 or similar lenses are still in the works… system needs some fast glass. Don’t pull a Sony on us!

  • I looked into those patents and they had f/2.8 aperture – the above patent is exactly what the new lens will be. Maybe there were also other calculations listed in those old patents.

      Hi Admin
      If you are sure this is the 10-100 lens it’s pretty sure the sensor is not larger than 2.7x (not even slightly larger). This patent shows an image diameter of 16mm.
      So the sensor is less or equal to 16mm.
      The older patents (where there are several that can be the predicted 30-110 lens) have all 17mm image heigth. They are not internal zoom and focus though.
      Given the zoom range I would have thought the 30-110 would have a higher quality than a 10X zoom.

      • BornOptimist, the problem is that those patents usually have several different calculations and designs for each lens and it is hard to guess the real intend.

        • BornOptimist

          The 30-107 patent no 20090147376 is a good bet for the last zoom lens. I’m not able to open the images in this patent, but does it show a group of elements with VR?
          Otherwise there are not much difference between each example in this patent. They are all more or less 30-107, f4 – 5.6, TL 76-105
          With flange distance of 18mm (guessing) this means a lens that is 58 – 87 mm. In other words a 300 mm that is 87mm long – that’s quite small.
