S5K2G1 sensor specifications and
compatible M12 lenses & C-mount lenses
S5K2G1 is a Samsung 1/1.8-inch CMOS image sensor in the ISOCELL family. The 3840x1920 array delivers 7.4 MP on 2.1um pixels, spanning a 9.02mm image circle. Commonlands matches M12 Lenses to that image circle and provides the calculated horizontal, vertical, and diagonal field of view at your chosen working distance.

Compatible Commonlands lenses for the S5K2G1. Field of View calculated with Distortion.
Each field of view below is calculated for the S5K2G1 active area (8.06 × 4.03 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 9.02 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 S5K2G1
- Best ~30° HFoV: Telephoto 14.2mm M12 Lens (CIL142) (14.2 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 S5K2G1: 32° H × 16° V (35° diagonal); image circle covers the full sensor; verified 2026-07-02.
- Best ~60° HFoV: 8mm C-Mount Lens (CIL521) (8 mm, f/1.5). Why: the closest covering option to 60° horizontal, chosen for general-purpose machine-vision framing. Field of view on the S5K2G1: 53° H × 28° V (59° diagonal); image circle covers the full sensor; verified 2026-07-02.
- Best ~120° HFoV: Wide-Angle 3.9mm M12 Lens (CIL339) (3.9 mm, f/1.6). Why: the closest covering option to 120° horizontal, chosen for wide navigation and room-scale coverage. Field of view on the S5K2G1: 121° H × 60° V (136° diagonal); image circle covers the full sensor; verified 2026-07-02.
- Lowest distortion: Low Distortion 4.2mm M12 Lens (CIL042) (4.2 mm, f/1.9). Why: measured -1% TV distortion, the flattest image among covering lenses. Field of view on the S5K2G1: 88° H × 51° V (95° diagonal); image circle covers the full sensor; verified 2026-07-02.
- Compact low-cost pick: Telephoto 16mm M12 Lens (CIL160) (16 mm, f/1.9). Why: the lowest-priced covering M12 barrel ($15). Field of view on the S5K2G1: 28° H × 14° V (32° diagonal); image circle covers the full sensor; verified 2026-07-02.

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 S5K2G1
Start from the field of view your application needs, then read across to the focal length that produces it on the S5K2G1. Confirm the lens image circle covers the 9.02 mm diagonal so the corners are not cropped, and check the lens resolution is rated for 7.4 MP or higher so it resolves the 2.1 µm pixels. For exact working-distance and object-size numbers, run the figures through the Commonlands field of view calculator.
