Description
NOTE: You must purchase the correct version for your ring system. See the second image above to find out which version you own.
Please also select the correct version for your Rokinon lens. If it has gears, select the CINE version.
The ZWO EAF bracket add-on for the Astrodymium Ring System will allow you to attach a ZWO EAF to your Rokinon / Samyang 135mm F/2 lens.
Does the EAF mount work by itself?
The EAF adapter does not work by itself, and is not a standalone product - this is a modular add-on. It is designed to only be used with the Astrodymium Ring System.
Why are there different versions of the bracket? What do they mean?
In 2024, the Astrodymium Ring System was updated to Version 6 (V6), which includes 6.0, 6.1, 6.2, etc.
The updated ring geometry means the older ZWO EAF mount (V4.0–V5.9) does not fit V6 rings.
V4.0–V5.9 rings require the original EAF mount, while V6 rings require the V6 EAF mount.
How do I figure out which version of the ring system I have?
