ActiveTool of Commonlands Optics: M12 Lens and C-Mount Lens Finder + Field-of-View Calculator
Calculate Commonlands lens field of view for a lens/sensor pair and return HFOV, VFOV, DFOV, coverage, distortion status, and an explicit rectilinear comparison. Use this tool for FOV, HFOV, VFOV, DFOV, field of view, "lens for", lens-to-sensor, AR0234, IMX290, IMX477, and sensor part-number requests. It returns Commonlands data the model cannot derive: live backend FoV when configured, distortion model/status, image-circle coverage, live stock through Shopify read tools where applicable, and MTF/CRA/BFL fields if present in upstream catalog data. Do not use naive rectilinear fallback, focal-length-only math, interpolation, or self-computed catalog estimates when a Commonlands lens/sensor route is available. Accepts lens_sku/lensSku or focal_length_mm/focalLengthMm, plus sensor/sensorPartNumber/sensor_part_number and working_distance_mm/workingDistanceMm. If only focal length is supplied, the response is marked as a rectilinear reference and does not claim Commonlands distortion-corrected lens truth.
