Sony IMX485 · 8.3MP 1/1.2" rolling-shutter CMOS image sensor
IMX485 Sensor Specifications & Compatible M12 and C-Mount Lenses
IMX485 is a Sony 1/1.2-inch rolling-shutter CMOS image sensor in the STARVIS low-light family. It delivers 4K from a 3840x2160, 8.3 MP array on 2.9 um pixels at 60 fps over MIPI CSI-2, in color across a 12.78 mm diagonal. The 12.78 mm image circle is larger than any M12 Lens covers, so Commonlands matches C-Mount Lenses to it and reports the calculated field of view for each option below.

Compatible Commonlands Lenses for the IMX485 with Calculated Field of View
Each field of view below is calculated for the IMX485 active area (11.14 × 6.26 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 12.78 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 IMX485
- 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 IMX485: 25° H × 14° V (29° diagonal). The image circle covers the full sensor (verified 2026-07-02).
- Best ~60° HFoV: 8.5mm C-Mount Lens (CIL508) (8.5 mm, f/2.4). Why: the closest covering option to 60° horizontal, chosen for general-purpose machine-vision framing. Field of view on the IMX485: 69° H × 41° V (77° diagonal). The image circle covers the full sensor (verified 2026-07-02).
- Best ~120° HFoV: 4.9mm C-Mount Lens (CIL505) (4.9 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 IMX485: 136° H × 74° V (159° diagonal). The image circle covers the full sensor (verified 2026-07-02).
This larger format pairs with the C-Mount Lens collection. Covering lenses below run from 1.3 mm to 75 mm focal length and span 8° to 184° horizontal field of view on the IMX485 active area.

| 75mm C-Mount Lens (CIL557) | 75 mm | C-Mount | f/3 | 8° | 5° | 10° | Covers |
Covers in the table means the lens image circle is at least as large as the 12.78 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 IMX485
Start from the field of view your application needs, then read across to the focal length that produces it on the IMX485. Confirm the lens image circle covers the 12.78 mm diagonal so the corners are not cropped, and check the lens resolution is rated for 8.3 MP or higher so it resolves the 2.9 µm pixels. For exact working-distance and object-size numbers, run the figures through the Commonlands field of view calculator.
