About this product

The NiSi 105mm Alpha Adapter is a precision-engineered accessory designed to connect S5 and S6 Series 150mm filter holders to lenses with 105mm front filter threads. Made from durable aluminum alloy, it provides a lightweight yet robust solution for photographers and videographers seeking to expand their filter system's compatibility. This adapter enables the use of S5 and S6 filter holders on ultrawide lenses by converting standard 105mm threads. It does not support circular polarizer filters or other circular S5/S6 filters when attached. Separate step-up adapters are available for 62mm, 77mm, 82mm, and 95mm lens threads, increasing versatility. The adapter requires a compatible S5 or S6 filter holder frame to function.

  • 105mm front thread compatibility
  • aluminum alloy construction
  • works with S5 and S6 holders
  • enables ultrawide lens use
  • separate step-up adapters available
  • wipe clean care
