Vizelex ND Throttle Lens Mount Combo Adapter - M42 Type 2 (42mm x1 Screw Mount) to Sony Alpha E-Mount Mirrorless Camera Body with Built-in Variable ND Filter (1 to 8 Stops)

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.

Note:
This is a two part adapter that uses a Canon EOS to Sony E-Mount ND Throttle as the base.
This is a manual adapter, so lens functions that rely on electronic communication with the camera body (autofocus, AE metering, image stabilization, etc.) will be disrupted.
Set your exposure manually or meter using your camera's Aperture Priority (stop-down) mode.
If your lens does not have a manual aperture control ring, it will stop down to its smallest f/stop by default.
