It is pleasing to introduce a new motorized filter wheel, with multiple filter capability. This new wheel employs exchangeable filter disks, allowing for multiple combinations, and has large 54mm openings on both sides. With these features, the EFW2 can easily support sensors up to full frame (35mm) format. The EFW2 also features a slick design, with a slim and lightweight profile.
For example, the distance between any ATIK camera and the wheel itself is 0mm, while still maintaining the possibility to rotating the camera to any desired position. Total extra back focus needed will be only 22mm.
