New: Kenko Lens2scope, a spotting scope adapter for lenses

I was doing some research online for lens scope converter in connection to a recent guest post on NikonRumors and it seems that Kenko recently released the Lens2scope - a spotting scope adapter for camera lenses, available for Nikon and Canon mounts. This adapter will let you use your existing lenses as a telescope with a 10x magnification. Check Amazon for pricing.

    Well it doesn’t seem to be a kenko product: http://www.lens2scope.com/product.html

  • freb

    Amazon has it ( http://www.amazon.com/Lens2scope-10mm-Eyepiece-Nikon-Angle/dp/B004GGNGV4/ref=sr_1_2?s=electronics&ie=UTF8&qid=1319332919&sr=1-2 ) but they say it is for DX lenses only. do anybody understand why?

    • King of Swaziland

      From what I can tell, they mean it works with FX and DX lenses, not just FX.

    • http://www.photosbygregstrong.com DeathK

      Hmmm. Amazon has all mounts available except Nikon. Go figure…

  • Bikinchris

    Dx pnly doesn’t make a lot of sense. Teh mount is the same and the adapter apparently only uses the center of the lens circle with a 10X eyepiece. Might be fun if I could use it with my 200-400!!!

    They should make a model with a battery that can power the lens VR

    I’m not buying one until they release the next version with a 3″ tilt LCD and an APS-C sensor that can do stills+1080 video on to a SD card ;P

    10x magnification?
    How are these things calculated? For what lens is that magnification?
    Ever thought if these before. Can someone break it down real quick?:-)

    • SimonG

      I think that is a typo . . . from the DPReview article on the Nikon product . . .

      “The power of the telescope is calculated by the focal length of your lens divided by 10, in my case a 51x telescope.”

      It’s quite simple really

      FX is considered 1x Magnification
      So a 50mm lens acts as a normal 50mm

      DX is 1.5x so a 50mm = 75mm
      (kind of)

      so 10x means that
      50 x 10 = 500mm Lens (Kind of)

      So if you have a 100mm lens on it
      it will function (for the most part)
      as if you had a 1000mm lens

        Even simpler… the eye-piece magnifies a frame that is 1/10th of the width of a full 35mm frame.

    Dahapurizumu? My Japanese is a little rusty, but my German is not: this awfully sounds like “Dachprisma”, which, one of those trusty online dictionaries says, is an Amici-prism. It would fit the purpose.

    • http://www.flickr.com/genotypewriter genotypewriter

      The Japanese are known for their misuse of technical terms… e.g. “translucent mirror”…

  • Peter

    No… crop factors have nothing to do with this. Crop factors just tell you the area the senesor covers.

    The focal lenght of a lens is the same even if it’s DX… DX lenses just have less coverage… they cover a area that is smaller, so that’s why you get extreme fall-off when used on a FF camera.

    So it really all comes down to how the adapter was designed and eye relief… you well get a different experience using a 400mm DX or 400 FX lens.

    Does it have AF and IS/VR?

    • Harold Ellis

      u want AF on a scope?

      • http://www.flickr.com/genotypewriter genotypewriter

        That was the main problem Columbus had in his day… Didn’t you know?

        • peterw

          Well, Keppler had solved it. And so did Galilei.
          Stupid Christopher to try it on a boat…

          (by the way did he? I thought he used eggs to find out if he had reached land.)

        It works well for me using long lenses, so why shouldn’t it work well on a scope, particularly if its already built in?

  • http://www.amazon.com/s/ref=nb_sb_ss_i_0_16?url=se LionelTwain52

    Has been available for some time

  • http://www.jpgmag.com/people/markwjr Mark

    Yepp. It’s been available since last year. And I can see it being a great thing for wildlife photographers. Especially the ones who don’t have enough room to carry around around another long lens, or real spotting scope.

    The magnification of a telescope is giverned by the focal length of the telescope (lens) and the magification of the eyepiece. Therefore this telescope adapter will produce a different magnification with lenses of different focal length. What would be really helpful would be if they told you what magnification a given focal length of lens produces. Just saying it gives 10x is misleading.

  • Camaman

    so this crops the picture giving you reduced resolution?

  • EverPhoto

    Magnification calculation is simple. Focal length of lens divided by focal length of eyepiece, in this case 10mm, so a 500mm lens would yield 50X, a 100mm lens would yield 10X, a 70-200mm lens would be a 7X-20X zoom scope. It has nothing to do with crop factor, whether a lens is FX or DX, etc. Put your 2X teleconverter on the 70-200 and now you would have a 14X-40X scope.

    • EverPhoto

      Forgot to mention that I made a simple eyepiece adapter long ago for Nikon lenses, including AF-S, so that I could use any of my telescope eyepieces on it, to increase or decrease the magnification. It’s not all that hard to make out of a rear lens cap and a Celestron 1.25″ Visual Back. You just cut a 1.25″ hole in the center of the cap and glue the visual back on it. Then grab any old 1.25″ telescope eyepiece to use. For an AF-S lens you need to make a little plastic peg to hold the aperture lever open, otherwise it’s all of the way closed.

      • Camaman

        How many mm Celestron 1.25″ eypiece do you use and why?
