Our adapters deliver infinity focus, manual aperture control, and a sturdy build for lasting quality. Back to Highlights Built-in Variable Neutral Density 2-8 stops 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. This concept in adapters has been praised by film makers and now Fotodiox has optimized the adapter for that same crowd. The Vizelex ND Throttle reduces light transmission by one stop when at its 'Min' position. The adapter helps maintain shallow depth of field in bright conditions while eliminating the tedious process of changing filters every time the exposure changes. With the filter positioned in the rear, image quality is better than if the same filter were mounted on the front of a lens. The variable ND filter is made from optical polycarbonate (CR39) for clarity and durability.

Warranty Limited 24-Months   • 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. • 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, the lens aperture will revert to its default position, which depending on the lens is either stopped down to its largest f-stop or opened up to its smallest f-stop. • To determine what the new 'Crop Factor' or 'Equivalent Focal Length' of the lens when used on your camera will be, please check the Fotodiox Knowledge Base article.
