Rare findings: Fastest (buyable) camera lens in the world for sale on eBay.


It happens only few times in the year to find this very rare lens. And it happens even less times to find it in top conditions, with all caps and already a T-mount adapter included. It’s the Canon 50mm f/0.75 you can find right now on eBay US (Click here). Unlike some other f/.075 lenses like Carl Zeiss (f/0.7 used by Stanley Kubrick), De Oude Delft, Rayxar this is a proper camera lens (the others are X-ray lenses or in case of the one used by Kubrick a limited edition NASA lens). The lens is 2/3 stops faster than the Voigtlander 0.95 MFT lens series. This is the fastest lens you can use on your Micro Four Thirds camera!

I found some image samples taken on Canon cameras on Flickr, Rakuten. But no one seems to have ever used this lens on a MFT camera…

  • MarcoSartoriPhoto

    Let’s see who will be the first saying that on MFT this is an f1.5 light gathering lens.. ;)

    • ha

      You need a speedbooster on this one, f0.5 will get you enough light…

      • MarcoSartoriPhoto

        Correct me if I’m wrong, but no speedbooster will help you reach f0.5.

        • Tom

          Doesn’t it! F0.75 * 0.71 = 0.5325. So light gathering would be ~0.53 but DOF would be 0.75*2*0.71 = 1.065.

          • Dmitry Anisimov

            Marco is right: no speedbooster will help you reach f0.5, even f0.6

      • I find it extremely amusing that people bitch about manual lenses, the price of M4/3 Voigtländers, etc., yet they foam at the mouth over the prospect of spending $500 on a Speedbooster so they can use manual lenses.

    • Damn Oly

      F1.5 is still very fast indeed , still in summilux teritory,. Those ppl are never learn.

      • Eosphoros

        “Those ppl are never learn” which people? What are they supposed to learn? Or whatever are you trying to say?

    • Bollox

      Nobody is going to say that – it’s common knowledge. As long as the usual sales reps don’t write that M43 can heal cancer and see through walls, or they don’t wring physics to marketing, that is :)

  • A7r Please

    Why on earth would you by this ultra fast lens to use on such a tiny Nano Four Thirds sensor? You want to use it on a proper sensor surely?

    • Horaciux

      just imagine it on speed booster :-)

    • Jules

      It would somehow have even less vignette on a 35mm sensor

    • bop800

      Don’t call me Surely

    • Rudi Calkovsky

      comparing penis’s…….

    • Dmitry Anisimov

      Well, because it IS for a small sensor, probably even smaller than 43

    • Photographer

      Because these are not photographers.

  • Bronica

    Upps. I bought it.

  • Vivek

    “Fastest buyable lens” Not!

    Fujinon 50/0.70 is faster and unlike this one is not a doorstop.

  • MacGyver

    @bronica:disqus i want to see it at work

    • Bronica

      Does it work? I’m not shure….

      • MacGyver

        I’ve had experience with x-ray lenses only work with macros, if this is meant to be a real lens as it is written, maybe it could work

        • Bronica

          I had a Delft lens. Only usable for makro.

  • Doug

    Auction ended…… Where are the photo links?


    Rodenstock 50mm .75….nuff said.


    I clicked on it again and now it says available but its in another language dude. WTF? How much is this damn thing…I’d buy it for the right price. Trophy piece kids.

  • Bronica

    Spanish. Who want ‘ the lens? I bought it a little bit to fast…

  • Bronica

    @admin: I think, it’s a X – ray lens. No infinity – focus :-(

  • Uberzone

    No aperture control and no infinity focus? No thanks!

  • Joe

    The Canon F0.95 50mm with Speedbooster/Lens Turbo adapter (.72x focal reducer) would be faster.

    • Dmitry Anisimov

      Nope, Speedboosters only take SLR lenses or those with big backfocus.
      Also, Speedboosters have their own limit, so f/# will be chopped at about f/0.9 no matter how fast is the lens before Speedbooster.

      • Joe

        I would prefer using my 25mm F0.95 Voigtlander Nokton over that Canon f0.75 macro lens that looks like a pain in the butt to use with no aperture control or infinity focus. The 18-35mm Sigma with Speedbooster would be the best fast zoom to use since it has an effective f1.2 with the MFT cameras.

  • Rudi Calkovsky

    NICE of you to post the ebay link AFTER you bought it buffoon admin!

  • Hifinut
    • Hifinut

      Sorry. Could be another April Fool joke.

  • Nashi

    Superficially looking at the rear element this shouldn’t be optically very different to the other X-ray/CRT lenses of similar application. E.g. the Rodenstock or the Oude Delft: https://www.flickr.com/photos/

    Like already mentioned very short flange distance and mostly too small an image circle even to cover APS-C (might be okay for 4/3 though).
