SESTO SENSO 3 LS Robotic Focusing Motor for Telephoto Lenses SESTO SENSO 3 LS is PrimaLuceLab’s “finally, someone made this properly” solution for motorized focusing of telephoto p hotographic lenses (Canon, Nikon, and others). Instead of relying on wobbly belt add-ons, it introduces the Lens Gear Clamp (LGC): a backlash-free, gear-driven coupling that engages the lens focus ring directly for precise, repeatable focusing. And because it includes an integrated position encoder, you can still tweak focus manually without losing position—plus you can enable Automatic Position Recovery to pull focus back where it belongs if it gets bumped. Add USB-C + WiFi, 2 million steps of resolution, compatibility with PLAY and ASCOM, and full integration features like ARCO port, DARK mode, and EAGLE GHOST mode, and you’ve got a lens-focused astro workflow that looks and behaves like a real imaging system—not a pile of accessories trying to cooperate. Built specifically for telephoto photographic lenses (Canon, Nikon, and other lenses with manual focus rings) Lens Gear Clamp (LGC) provides backlash-free, gear-driven focusing Directly drives the lens focus ring without external belts (optional belt available for very stiff focus rings) Uses an integrated rubber gear for high grip and smooth motion Integrated position encoder keeps motor position even if you manually rotate the lens focus ring Optional Automatic Position Recovery (0–20s delay) returns the lens to the prior focus position if focus is moved High-resolution motor: 2,000,000 steps for fine control and repeatable autofocus routines USB-C for reliable control from Windows PC or EAGLE Built-in WiFi + included Virtual HandPad for phone/tablet control (no physical hand controller needed) PLAY software compatible (focus control + autofocus) ASCOM driver included for third-party software integration ARCO rotator port for direct ARCO connection (power + data via one short cable) DARK mode with dimmable LEDs (or fully off to eliminate stray light during imaging) GHOST mode support with EAGLE to remove the USB cable (cleaner wiring + backup comms path) Temperature sensor port for optional probe and temperature-compensated focus (software support dependent) Arca-Swiss style mount built into the LGC Makes it easy to attach to PLUS Vixen-style dovetail bars and mount on any Vixen clamp-equipped mount Includes two interchangeable rubber gears for different focus ring widths One for focus rings up to 18mm wide One for focus rings over 18mm wide Made in Italy (developed and manufactured by PrimaLuceLab) Lens compatibility examples (not limited to): Nikkor Z 70–200mm f/2.8 VR S Nikkor Z 100–400mm f/4.5–5.6 VR S Nikkor Z 24–120mm f/4 S Nikkor Z 24–70mm f/4 S Other telephoto lenses with a manual focus ring Specifications Product type: Robotic focusing motor for telephoto photographic lenses Coupling system: Lens Gear Clamp (LGC), backlash-free gear-driven engagement (belt optional for stiff rings) Position tracking: Integrated encoder (manual movement supported without losing position) Automatic Position Recovery: Optional, delay adjustable 0–20 seconds Motor resolution: Up to 2,000,000 steps Connectivity: USB-C (PC/EAGLE control) WiFi (Virtual HandPad via smartphone/tablet) Software / Drivers: PLAY compatible (focus control + autofocus) ASCOM driver included ARCO support: Dedicated ARCO port (single cable for power + data) Modes: DARK mode (dimmable LEDs, can be fully off) GHOST mode with EAGLE (operate without USB cable / backup channel) Power input: 12V DC, 5.5/2.5mm, center-positive Sensor port: Temperature sensor port (optional probe) Mounting interface: Arca-Swiss style mount (LGC), compatible with PLUS Vixen-style dovetail bars Weight: 515 g (1.1 lb) Manufacturing: Developed and manufactured in Italy What’s in the box?
