    Take our expertise in lens mount adapters and add something unexpected: a built-in Variable ND filter. The ND Throttle opens up new creative possibilities, like long exposure and shallow depth of field, even in bright conditions. No more carrying around a camera bag full of ND filters. Built-in variable ND means easy and convenient image control over any lens that you attach - even wide angle lenses that don't work with front-mounted variable ND filters. We offer dozens of choices for both mirrorless and DSLR and film cameras.
