MT9M114 sensor specifications and
compatible M12 lenses & C-mount lenses
The MT9M114 from onsemi is a 1/4" rolling-shutter CMOS image sensor with on-chip image processing, a legacy Aptina SOC design for color modules. It resolves 1280x960 (1.2 MP) on 1.9 um pixels at 30 fps over a parallel or MIPI interface, with a 3.04 mm diagonal. Commonlands matches M12 Lenses to the MT9M114 image circle and reports the calculated horizontal, vertical, and diagonal field of view for each lens.

Compatible Commonlands lenses for the MT9M114. Field of View calculated with Distortion.
Each field of view below is calculated for the MT9M114 active area (2.43 × 1.82 mm) using our MCP server and Field of view calculator. The rectilinear formula FoV = 2 × arctan(dimension ÷ (2 × focal length)) is incorrect for many lenses as it doesn't include distortion. Coverage shows whether the lens image circle covers the 3.04 mm sensor diagonal. Fisheye and f-theta lenses do not follow the rectilinear formula, so their entries link to the product page for the mapped field of view.
Engineering picks for the MT9M114
- Best ~30° HFoV: Low Distortion 4.4mm M12 Lens (CIL043) (4.4 mm, f/3.2). Why: the closest covering option to 30° horizontal, chosen for tight inspection framing and long read ranges. Field of view on the MT9M114: 31° H × 23° V (38° diagonal); image circle covers the full sensor; verified 2026-07-02.
- Best ~60° HFoV: Low Distortion 2.2mm M12 Lens (CIL023) (2.2 mm, f/2.2). Why: the closest covering option to 60° horizontal, chosen for general-purpose machine-vision framing. Field of view on the MT9M114: 59° H × 45° V (70° diagonal); image circle covers the full sensor; verified 2026-07-02.
- Best ~120° HFoV: Fisheye 1.1mm M12 Lens (CIL212) (1.1 mm, f/2.2). Why: the closest covering option to 120° horizontal, chosen for wide navigation and room-scale coverage. Field of view on the MT9M114: 131° H × 97° V (168° diagonal); image circle covers the full sensor; verified 2026-07-02.
- Best low light: 8mm C-Mount Lens (CIL521) (8 mm, f/1.5). Why: the fastest covering aperture (f/1.5), which collects the most light per pixel. Field of view on the MT9M114: 17° H × 13° V (22° diagonal); image circle covers the full sensor; verified 2026-07-02.
- Compact low-cost pick: Fisheye 1.55mm M12 Lens (CIL216) (1.55 mm, f/2.2). Why: the lowest-priced covering M12 barrel ($12). Field of view on the MT9M114: 92° H × 68° V (117° diagonal); image circle covers the full sensor; verified 2026-07-02.
Commonlands offers 72 lens options for the MT9M114: M12 Lenses and C-Mount Lenses from 0.8 mm to 100 mm focal length, spanning 1° to 162° horizontal field of view on the MT9M114 active area.
Coverage key: covers = lens image circle ≥ sensor diagonal; crops = image circle smaller than the diagonal (expect vignetting at the corners); verify = image circle not published for this lens — ask our engineers to confirm coverage.
How to choose a lens for the MT9M114
Start from the field of view your application needs, then read across to the focal length that produces it on the MT9M114. Confirm the lens image circle covers the 3.04 mm diagonal so the corners are not cropped, and check the lens resolution is rated for 1.2 MP or higher so it resolves the 1.9 µm pixels. For exact working-distance and object-size numbers, run the figures through the Commonlands field of view calculator.
