Sony IMX728 · 8.3MP 1/1.7" rolling-shutter CMOS image sensor
IMX728 Sensor Specifications & Compatible M12 and C-Mount Lenses
IMX728 is a Sony 1/1.7" rolling-shutter CMOS image sensor built on the stacked Exmor RS architecture. It captures 3840x2160 (8.3 MP) on 2.1 um pixels at 30 fps through a MIPI CSI-2 interface, with a 9.25 mm diagonal. Pick an M12 Lens for the 9.25 mm image circle from the table below, built on measured lens data rather than focal-length-only estimates.

Lens selection for the IMX728 with calculated field of view
Each field of view below is calculated for the IMX728 active area (8.06 × 4.54 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 focal length, mount, aperture (F#), and coverage. Follow the product links for distortion, ingress protection, dimensions, and resolution specifications. Coverage compares the lens image circle with the 9.25 mm sensor diagonal. Entries marked Circular image do not cover the full diagonal; part of the sensor lies outside the image circle. Run working-distance and object-size numbers through the field of view calculator.
Engineering picks for the IMX728
- 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 IMX728: 32° H × 18° V (36° 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 IMX728: 53° H × 32° V (60° 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 IMX728: 121° H × 67° V (139° 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 IMX728: 88° H × 57° V (96° 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 IMX728: 28° H × 16° 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 9.25 mm sensor diagonal. Confirm corner illumination and MTF at your aperture, wavelength, and working distance. A complete circular fisheye image fits inside the sensor only when its diameter is no larger than the sensor's short side. 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 IMX728
Start from the field of view and working distance your application needs. Confirm that the lens image circle covers the active sensor diagonal and that the mount provides the required focus travel and rear clearance. A lens megapixel rating alone does not establish resolution on this sensor. Compare measured MTF at the spatial frequencies your task needs, at the intended aperture, wavelength, distance, and field position, accounting for the 2.1 µm pixel pitch. Estimate framing with the Commonlands field of view calculator.
