CHF 105
Reference RAF-0016
Choose either Canon EF or Nikon F depending on your lens. Both versions accept a 2-inch filter, but their mounts and thicknesses are not interchangeable.
2-inch filter holder for attaching a Canon EF lens to a compatible ZWO ASI camera.
The Canon EF and Nikon F mounts are two distinct variants; select the one that matches your lens. The filter holder can be removed without unscrewing the entire optical assembly and uses a magnetic retention system. Mounting on full-frame cameras requires the manufacturer-provided M54M–M42F adapter. Check the height of the filter mount and the camera’s working distance. This adapter does not convert a Nikon mount to a Canon mount, or vice versa.
