Features
- Standard Ø15 mm Retaining Ring
- Compatible with our SM Series of Lens Mounts and Lens Tubes
Our SM15RR, Ø15 mm, Standard Retaining Ring is compatible with our extensive line of SM Series lens tubes and mounts. Securing an optic using a retaining ring is probably the most stable method for holding the optic since the optic is retained along its entire edge, not just at a few points. The retaining ring is thin so that the clear aperture of the optic is only minimally affected.
