SESTO SENSO 3 LS, motor for camera lenses<\/h3>\n

SESTO SENSO 3 LS motorizes the focus ring of compatible telephoto lenses. PrimaLuceLab pairs it with the Lens Gear Clamp, a rubber-coated gear interface that directly drives the ring, featuring a built-in encoder to track the motor\u2019s position.<\/p>\n

Turn the lens ring<\/h3>\n

The Lens Gear Clamp places a rubber wheel in contact with the focus ring. It eliminates the need for an external belt in standard setups; an optional belt is available for lenses with very stiff focus mechanisms. The two interchangeable wheels are used to adjust the contact to the width of the ring. The LS version is designed for camera lenses and should not be confused with motors intended for telescope eyepiece holders.<\/p>\n

Selection of Objectives and Media<\/h3>\n

The manufacturer specifically lists the Nikkor Z 70-200 mm f\/2.8 VR S, Z 100-400 mm f\/4.5-5.6 VR S, Z 24-120 mm f\/4 S, and Z 24-70 mm f\/4 S. This list does not guarantee universal compatibility with all Canon or Nikon lenses. The Arca-Swiss clamp allows for mounting on a compatible Vixen PLUS rail. An optional secondary mount is available for lenses that lack a suitable camera mount.<\/p>\n

Manual adjustments and position reset<\/h3>\n

The encoder retains the motor reference when the user manually rotates the ring while the device is installed and powered on. The Automatic Position Recovery feature can return the system to its previous position after a manual rotation or an unintended movement, with a delay of 0 to 20 seconds. The manufacturer notes, however, that the encoder detects movements of the motor shaft: it does not measure any internal slippage within the lens mechanism.<\/p>\n

Commands and Extensions<\/h3>\n

The USB-C port connects the motor to EAGLE or a Windows PC for use with PLAY or ASCOM-compatible software. Wi-Fi provides access to the Virtual HandPad from a phone or tablet. GHOST mode uses EAGLE to eliminate the need for a USB cable on a compatible setup; DARK mode adjusts or turns off the LEDs. The ARCO port powers and controls an optional rotator via a dedicated connection. The temperature port accepts an optional sensor for software that supports thermal compensation.<\/p>\n

Announced Content<\/h3>\n

The package includes the SESTO SENSO 3 LS, the Arca-Swiss clamp, 6-mm and 18-mm rubber gears, a USB-C to USB-A cable, a 12 V cable with a cigarette lighter plug, hex keys, two 1\/4\u2033-20 camera screws, and the installation guide. The lens, the bar, ARCO, the thermal sensor, and the secondary mount are not listed here.<\/p>\n
