The build quality and solidity of the new Atik EFW2 motorized USB filter wheel is very impressive! The case is milled from a solid aluminium block, the filter disk is sturdy and the motor selected for long-term reliability.
Atik EFW2 & OAG Review
With exchangeable filter disks and large 54mm apertures on both sides the EFW2 can easily support sensors up to full frame (35mm) format. Atik cameras screw flush onto the wheel and will rotate without an additional adapter (adapter required for Atik-11000). Total extra backfocus required is only 22mm.
Initial filter disk options include 5x2” mounted, 7x36mm and 9x1.25” mounted. On the software side, the EFW2 has an ASCOM compliant driver so any compliant software can control it. Additionally, the EFW2 will work with Atik's own Artemis Capture software for easy, simple and efficient operation.
UPDATE: Following the comments offered in the product review below Atik have made available a low profile (adds only 1.3mm to the distance) M54 to M42 T male-female adapter which enables the Atik EFW2 filter wheel to be fitted to a male T-thread.
