The Vizelex ND Throttle is well known for having a built-in variable neutral density filter that offers 2 to 8 stops of light reduction. Fotodiox Pro adapters feature all-metal, no plastic construction to create a secure connection between your glass and camera that will not degrade over time, keeping the lens-camera connection secure with every use. We use chrome plated brass mounts for enhanced durability and reliability. All Fotodiox products are backed by our 24-month Fotodiox Manufacturer Warranty.

Compatible with L-Mount Alliance Camera Compatibility (popular models include):

Notes:
* 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.
* Some cameras need to be set a certain way to work with our adapters or you may get a message such as 'Error Lens Not Attached - Check lens'. Please check the support articles on the Fotodiox Knowledge Base for possible solutions on a variety of camera brands.
* 'Focus-By-Wire' lenses (such as Canon's STM or Nikons AF-P) requires power to engage the manual focus rings on the lens, since manual lens mount adapters do not power the lens, those lenses will not be able to focus.
* All pictures are for illustration purposes only. Actual product may vary slightly due to ongoing improvements in design.
