Sony IMX531 · 20.4MP 1.1" global-shutter CMOS image sensor
IMX531 Sensor Specifications & Compatible M12 and C-Mount Lenses
IMX531 is a Sony 1.1-inch global-shutter CMOS image sensor in the Pregius S global-shutter machine-vision family. Its square 4512x4512, 20.4 MP array uses 2.74 um pixels at 109 fps over SLVS-EC, in color or mono across a 17.48 mm diagonal. Commonlands matches M12 Lenses to its image circle and calculates the horizontal, vertical, and diagonal field of view for each focal length.

Compatible Commonlands Lenses for the IMX531 with Calculated Field of View
Each field of view below is calculated for the IMX531 active area (12.36 × 12.36 mm) from Commonlands’ per-lens field-of-view data, which reflects each lens’s real distortion rather than a focal-length-only estimate. Alongside the horizontal, vertical, and diagonal field of view, each row lists the lens aperture (F#), distortion, ingress protection, total track length (TTL), and rated resolution, so you can shortlist on optics and mechanics in one pass. Coverage shows whether the lens image circle covers the 17.48 mm sensor diagonal. Only lenses that cover the full diagonal are listed. Run exact working-distance and object-size numbers through the field of view calculator.
Engineering picks for the IMX531
- Best ~30° HFoV: 25mm C-Mount Lens (CIL554) (25 mm, f/2.6). Why: the closest covering option to 30° horizontal, chosen for tight inspection framing and long read ranges. Field of view on the IMX531: 28° H × 28° V (39° diagonal); image circle covers the full sensor; verified 2026-07-02.
- Best ~60° HFoV: 12mm C-Mount Lens (CIL552) (12 mm, f/2.8). Why: the closest covering option to 60° horizontal, chosen for general-purpose machine-vision framing. Field of view on the IMX531: 55° H × 55° V (72° diagonal); image circle covers the full sensor; verified 2026-07-02.
- Best low light: 8.5mm C-Mount Lens (CIL508) (8.5 mm, f/2.4). Why: the fastest covering aperture (f/2.4), which collects the most light per pixel. Field of view on the IMX531: 75° H × 75° V (98° diagonal); image circle covers the full sensor; verified 2026-07-02.
Commonlands offers 8 lens options for the IMX531: M12 Lenses and C-Mount Lenses from 1.3 mm to 75 mm focal length, spanning 9° to 184° horizontal field of view on the IMX531 active area.

| 75mm C-Mount Lens (CIL557) | 75 mm | C-mount | f/3 | 9° | 9° | 13° | Covers |
covers means the lens image circle is at least as large as the 17.48 mm sensor diagonal, so the corners are not cropped. Need a focal length or coverage that is not listed here? Ask our engineers to confirm a match.
How to choose a lens for the IMX531
Start from the field of view your application needs, then read across to the focal length that produces it on the IMX531. Confirm the lens image circle covers the 17.48 mm diagonal so the corners are not cropped, and check the lens resolution is rated for 20.4 MP or higher so it resolves the 2.74 µm pixels. For exact working-distance and object-size numbers, run the figures through the Commonlands field of view calculator.
