Key Features
  • Snap-In Solid Neutral Density Filter
  • Fits Sigma MC-21 Lens Mount Adapter
  • 65,000x Filter Factor, 16-Stop
  • Reduce Shutter Speeds
This Adapter Mount Format PowerND 4.8 Filter for Sigma MC-21 Lens Mount Adapter from Aurora Aperture is an ND filter with a 65,000x filter factor that provides a 16-stop exposure reduction. Its 4.8 density creates a darkening of the entire image, allowing you to photograph with a wider aperture or slower shutter speed than normally required. By slowing your exposure time or increasing your aperture, you can control depth of field and convey movement more easily. This neutral density filter is mounted within a durable, aluminum alloy filter frame that is made specifically to fit within a separately available Sigma MC-21 Lens Mount Adapter. By mounting an Aurora Aperture Adapter Mount Format Filter inside a compatible lens mount adapter, that filter can be used for multiple lenses even if those lenses have differing or non-existent front filter threads.
