Compatible Commonlands Lenses for the S5K2G1 with Calculated Field of View
Each field of view below is calculated for the S5K2G1 active area (8.06 × 4.03 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 9.02 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 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). The 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). The 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). The 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). The 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). The image circle covers the full sensor (verified 2026-07-02).

Covers in the table means the lens image circle is at least as large as the 9.02 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 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.
