Provides 300? (max) focus throw – The V-AF MF adapter increases the focus throw of the lens up to 300? allowing much more precise control when using a follow focus. The adapter uses a 0.8-gear pitch.
Dedicated controls – With the MF adapter handling focusing, this frees up the lens ring to specifically control the aperture. When the adapter is attached, the MF-AF switch also operates as the dedicated custom mode.
Matte Box Compatibility – The MF adapter is compatible with the 95mm matte boxes.
Lightweight design – The MF adapter continues the V-AF system’s lightweight ethos, making it perfect for long periods of handheld use.
