The Ø26 mm adapter for SESTO SENSO 2 (PrimaLuceLab, SKU: SESTOSENSO-AD26II ) enables the second generation SESTO SENSO drive to be mounted on focusers with a thinner 26 mm diameter focusing shaft. The ring replaces the standard Ø25 mm clamp and uses the same, self-centering clamp mechanism – guaranteeing a secure grip without clamping screws and without the risk of stepper motor slippage.
