Fotodiox Vizelex ND Throttle Follow Up Video

Although we still don't have any scientific tests on the sharpness coming from the new Fotodiox Vizelex Throttle Variable ND Filter 'Lens Adapter', this follow up video answers a few great questions.

Here's another thing they didn't cover which has been a main reason I would consider using the adapter. A fisheye lens on a BlackMagic Pocket Cinema Camera is not so 'fish-eye', and it's one of my go to lenses for wide angle shots. Unfortunately, some ultra wide angle or fisheye lenses (in which the front optic protrudes past the housing) are unable to accept front filters. With the variable ND sitting behind the lens, you can control your image in bright outdoor conditions. I know Rokinon has announced a few great wide angle lenses for Mirrorless cameras, but this situation may be a reason why adapting the larger EF or Nikon mounts would be better.

Hopefully the Micro Four Thirds version comes out soon for the GH4 as I hear it will have a different crop factor than a typical GH3, so i'll really be digging into these ultra wide angle lenses. You can find the (click here)

    @mpicmac - I think you totally missed the idea. There are plenty of 'Canon' mount manual lenses from Zeiss, Rokinon, Voigtlander, etc. There is a need for something like this.

    very great idea, i like the concept very much.
    i buy one already.
    the problem is i can not change aperture at all, that is ridiculous.
    who want to shoot wide aperture all time.

    do not buy one !!!

    comment to Fotodiox: this concept may good for manual lens or lens that can change aperture on the lens itself. for cannon "NO GOOD"


  3. Hi Emm, thanks for brining this to our attention 🙂

    Hopefully you can do a $300 HolyManta vs $100 ND throttle test for color and sharpness. (maybe with the Tiffen and LCW filters added in too)

    @Jeff, you cannot have this in a canon ef/efs - ef/efs mount adapter (no room for the ND glass) but it is possible to have it in an EF lens - EFm mount adapter.

    @Will, you cannot have this in a micro 4/3 - micro 4/3 mount adapter (no room for the ND glass) but it is possible to have it in an EF lens-m43 mount adapter, which I agree should be the next version.

    @Tulio, I assume these do not has electronic Iris control because they seem to be an alternative for exposure control, which is a great addition to a "dumb adapter" but you also miss out on IS and AF controls of the "smart adapters".

    I want a micro 4/3 lens to NEX mount ND Adapter, so that I can then stack on a Canon EF lens to Micro 4/3 mount speedbooster to an FS100 LOL (seriously though, it probably wouldn't work.)

    I would like to see a straight Micro Four Third to Micro Four Thirds variable ND filter.

    My second request would be Micro Four Third to Canon.

    The idea of a Variable ND filter/Speed Booster is a great idea too!!

    Thanks for asking my input!!

    @Tulio - Two different tools at this point. We can ask, but it's most likely impossible to make a speed booster + variable ND in the same adapter.
