ND Throttle | Lens Adapters With ND Filters Built-In

In the world of lens adapters, Metabones tends to get most of the press, and that’s not to say it’s not merited – they’re brilliant. However, as brilliant as they are, they are by no means all encompassing, and their price point may be prohibitive for more than a few. FotoDiox has taken to making some extremely popular adapters that not only are direct alternatives, but fill market segment gaps. New to the FotoDiox line-up is their Vizelex ND Throttle, which is essentially a lens adapter with a variable ND filter built right in that goes from ND2 all the way to ND1000.

There’s a lot of appeal to be found in having a built-in ND filter. To anyone that has ever used any type of filter or filter system, you are more than aware that they can be cumbersome, and sometimes you need different filters for different lenses and camera systems. Even if this annoyance is removed from the equation, having an ND filter on the front of a camera renders some broadly irritating and strange patterns in the image. Strangely, and for reasons far beyond my technical pay grade, this issue resolves, and is non-existent once the filter is placed behind the lens elements, as is the case with the ND Throttle.

It’s also great to be able to go from ND2 to ND1000 which is essentially a fade to black. Videographers will surely get a kick out of this feature, as they will altogether with the product. There are huge applications and relevancy for something like this for videographers, amateur and above.

The size of the adapters remains in a typical form factor, which is somewhat surprising, and the movement to adjust the level of opacity of the filter is smooth all the way through the throw. It feels well built, and not like a gimmick or afterthought, and there are a plethora of options for almost any mount.

It isn’t, however, without limitations; It is not a smart adapter, so you’ll lose electronic connection between the lens and camera, and really will work best with lenses that have a manual aperture ring. Ability to operate aperture function will vary depending on the lens. I asked Bohus if there were plans to make these ‘smart’ and despite the challenges that would be introduced, he seemed to be already considering it, and of course, it would depend on demand – especially as these are selling out so quickly as is.

Hopefully we’ll be getting some in to test in the near future, but they look promising, and a focus of interest here at PhotoPlus, and click here to find out more in the time being.

A big thank you to B&H Photo for sponsoring our team while here at PhotoPlus, and making it possible for us to have a successful event covering as much floor space as we could in just a couple days. This was my first PhotoPlus event, but it will definitely not be my last.

    I suspect that the price of this adapter goes up quite a bit of you look to maintain control of the lens because, basically, they’d need a controller to convert the Sony signal to one that the Canon lens understands. I have a feeling that some would pay the premium, but maybe they did some research that suggests otherwise.

    In any event, would love to see something like that on the Nikon too. I can live with full manual lens controls given that this would be used on a tripod under much more controlled conditions.

      They have a Nikon G to Sony EF mount version–I own one and it’s brilliant. The Nikon model has built-in smooth aperture control dial as well as the ND dial. So, you not only get de-clicked aperture functionality (for all Nikon F-mount lenses–including G lenses), you also get 3-10 stops of ND built-in to the mount with non of the color cast and cross-pattern issues you get with front-mounted filters (let alone the different sizes of filters you might need).

      This one is a total winner in my book. Works great when you need/want to use SLog-2 on your A7s.

    I don’t find this practical at all. I would rather use a variable nd filter

    If these were smart adapters I would seriously consider throwing away my canon and switching to sony…or am I going mad?

    Something like this in a Nikon mount with circular polarizing abilities would be sweet – it would be great for automotive photography!

    Ooh, this would be great to see in other lens mount as well!

    Hmm if I read correctly, you won’t be able to set your aperture via the mount or with electronic control, great concept, but hard to use with f1.4 lenses
