Sony IMX249 · 2.4MP 1/1.2" global-shutter CMOS image sensor
IMX249 Sensor Specifications & Compatible M12 and C-Mount Lenses
IMX249 is a Sony 1/1.2-inch global-shutter CMOS image sensor from the Pregius family, a cost-efficient choice for global-shutter machine vision. It runs 1936x1216 (2.4 MP) at 30 fps with 5.86um pixels on a 13.40mm diagonal over LVDS in color or mono. A sensor this size needs C-Mount coverage rather than an M12 Lens, and the table below lists every covering option with its calculated field of view.

Lens selection for the IMX249 with calculated field of view
Each field of view below is calculated for the IMX249 active area (11.34 × 7.13 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 13.4 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 IMX249
- 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 IMX249: 25.6° H × 16.2° V (30° diagonal). The image circle covers the full sensor (rectilinear estimate, computed 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 IMX249: 67.4° H × 45.5° V (76.5° diagonal). The image circle covers the full sensor (rectilinear estimate, computed 2026-07-02).
- Best low light: 4.9mm C-Mount Lens (CIL505) (4.9 mm, f/2.2). Why: the fastest covering aperture (f/2.2), which collects the most light per pixel. Field of view on the IMX249: 98.3° H × 72.1° V (107.6° diagonal). The image circle covers the full sensor (rectilinear estimate, computed 2026-07-02).
This larger format pairs with the C-Mount Lens collection. Covering lenses below run from 4.9 mm to 75 mm focal length and span 8.6° to 98.3° horizontal field of view on the IMX249 active area.

| 75mm C-Mount Lens (CIL557) | 75 mm | Cマウント | f/3 | 8.6° | 5.4° | 10.2° | Covers |
Covers in the table means the lens image circle is at least as large as the 13.4 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 IMX249
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 5.86 µm pixel pitch. Estimate framing with the Commonlands field of view calculator.
