L085-DEVKIT Brief L085 is 5.3-130mm focal length (25x) motorized zoom lens is designed for 1/2.7" image sensors, has zoom/focus/iris functions, designed for 5M sensors. Specifications Optics Image sensor 1/2.7" Effective image area > 6.8mm Focal distance 5.3 ~ 130mm / ±5% Aperture f/1.6 ~ f/4.3 Focus range WIDE: 0.1m - infinity TELE: 1.5m - infinity Field of view (D=8.81mm) WIDE: 67.9° TELE: 2.8° Distortion WIDE: -2.9% TELE: 0.3% Recommended image sensor IMX335 Mechanics Flange back (FB, see diagram below) -0.325mm (in glass t=0.3 IRCF) Lens zoom structure The stepper motor is directly connected to the screw Lens focusing structure The stepper motor is directly connected to the screw Lens size Length: 92.49mm Width: 50.1mm Height: 43.8mm Front end diameter:  44.6mm Weight 116g (+controller 7.8g) In order to accommodate different image sensors, the focal distance is set back by flange back (FB) distance. The actual distance for a specific sensor has to be calculated and spacers used. If the image plane is not set correctly, focus irregularities in the projected picture are expected.
