We've taken our experience with rings for the Rokinon/Samyang 135 f/2 lens and created a system that can be adapted to just about any camera lens or small/medium telescope. With the same modular design, you can attach a ZWO electronic autofocuser, guidescope, mini PC, ASIAir, and other accessories.

Features:
Material: Thick-walled, carbon fiber-infused PETG with stainless steel fasteners. Our custom blend of carbon fiber PETG performs better than commercially available PETG-CF blends.
Modularity: Interchangeable add-on accessory plates allow you to mix, match, and rearrange gear to suit your setup.
Lens Grip: Weather-resistant EPDM foam lining securely grips your lens.
Geared ZWO Electronic Autofocuser Adapter: Allows for easy lens rotation and precise, backlash-free autofocus.
Comes with gears for both the old ZWO EAF and the new ZWO EAF-N and EAF Pro.
Accessory Mounting:
Universal Findershoe Saddle: Holds a guidescope, ASIAir, and other items with a finderscope dovetail.
General-Purpose Accessory Rail: Allows you to bolt on accessories like a powerbox or mini PC. Also serves as a flat surface to apply adhesive-backed Velcro to, should you wish to attach components that can't be bolted on.
Ring Sizes:
Standard Width: 15mm (for most lenses).
Extra Thick: 30mm (for heavy lenses and added rigidity).
Robust Hinge: Double-shear hinge design prevents bolts from backing out over time.
Compatibility: Fits most lenses and small/medium telescopes from all brands -- Canon, Nikon, Sigma, Rokinon/Samyang, Askar, SVBONY, and more.
We highly recommend using a pair of calipers to measure your lens. A cheap pair of calipers is a great tool to have in this hobby. Do not round the numbers you measure with your calipers.
