The IMX219 and IMX477 are Sony CMOS image sensors used in two of the most popular Raspberry Pi cameras. Understanding the differences between these sensors helps you choose the right camera for your project – whether that’s OpenCV vision work, astrophotography, machine learning inference, or industrial inspection. This Raspberry Pi camera comparison covers sensor specifications, optical format, low-light performance, and use case recommendations for India makers.

Sensor Specifications Compared
| Specification | IMX219 | IMX477 |
|---|---|---|
| Resolution | 8MP (3280×2464) | 12.3MP (4056×3040) |
| Pixel Size | 1.12 micron | 1.55 micron |
| Sensor Format | 1/4 inch | 1/2.3 inch |
| Sensor Diagonal | 4.6mm | 7.9mm |
| SNR | 36.1 dB | 40+ dB |
| Full Resolution FPS | 21 FPS | 10 FPS |
| 4K Video FPS | N/A | Not natively supported |
| Interface | MIPI CSI-2 | MIPI CSI-2 |
| Mount | Fixed M12 or CSP | C/CS mount (official HQ) |
Optical Format and Lens Compatibility
The IMX477’s larger 1/2.3 inch format is the key differentiator. A larger sensor captures more light and allows use of higher-quality interchangeable lenses:
- IMX219: Fixed M12 lens (on most modules) or tiny native lens. Cannot accept standard C-mount or CS-mount lenses.
- IMX477 (HQ Camera): C/CS mount – accepts hundreds of industrial, machine vision, and photographic lenses. Telephoto, macro, wide angle all available.
This makes IMX477 the choice for precision inspection or photography where you need to swap lenses for different field-of-view requirements.
Arducam IMX477 12MP HQ Camera
Sony IMX477 sensor in Raspberry Pi HQ Camera format. 12.3MP, C/CS mount for interchangeable lenses, large 1.55 micron pixels for superior low-light. The premium Pi camera for serious photography, astrophotography, and machine vision.
Arducam IMX219 8MP Camera Module
Sony IMX219 sensor, 8MP resolution, compatible with Raspberry Pi, Jetson Nano, and Orange Pi. Excellent value for computer vision, object detection, and streaming projects. Multiple FOV variants available.
Low-Light Performance
IMX477 significantly outperforms IMX219 in low-light conditions due to:
- Larger pixels (1.55 vs 1.12 micron): Each IMX477 pixel collects ~1.9x more light than IMX219
- Larger sensor area: IMX477 sensor area is ~2.9x larger – gathers substantially more total light
- Full-well capacity: Larger pixels have higher full-well capacity, reducing overexposure in high-contrast scenes
In practical terms: at the same ISO and exposure, IMX477 shots show noticeably less noise in shadows. For India night photography – festival lights, street scenes in dimly lit areas – IMX477 is the clear choice.
Frame Rate and Resolution Modes
IMX219 frame rates with Raspberry Pi:
- 3280×2464 (full resolution): 21 FPS
- 1920×1080: 30 FPS
- 1640×1232 (4:3 partial): 40 FPS
- 1280×720: 60 FPS
- 640×480: 90+ FPS
IMX477 frame rates with Raspberry Pi:
- 4056×3040 (full resolution): 10 FPS
- 2028×1520: 40 FPS
- 1920×1080 (cropped): 50 FPS
- 1280×720: 120 FPS
For high-speed vision applications (conveyor inspection, ball tracking), IMX219 at 720p/90FPS can be more useful than IMX477 at lower frame rates.
Image Quality: Dynamic Range and Noise
IMX477 offers approximately 12-13 stops of dynamic range vs IMX219’s 10-11 stops. This matters for outdoor photography in India where scenes often have bright sky and dark shadows (high dynamic range situations). IMX477’s HDR mode captures two exposures and blends them, recovering detail in both highlights and shadows.
Waveshare IMX219-77 Camera Module
IMX219 with 77-degree FOV in a slim module. Compatible with Raspberry Pi and Jetson Nano. Good choice for computer vision projects where cost matters more than maximum image quality. Well-priced option in India for prototyping multiple camera setups.
Use Case Recommendations
Choose IMX219 when:
- Computer vision and OpenCV projects (object detection, lane detection, gesture recognition)
- Budget-constrained projects (IMX219 modules cost Rs 800-1,500 vs Rs 6,000-8,000 for IMX477 HQ)
- Jetson Nano integration (IMX219 is the officially supported sensor)
- Wide-angle coverage needed (many wide-angle variants available)
- High frame rate needed at lower resolution
Choose IMX477 when:
- Astrophotography or low-light photography
- Interchangeable lens required (macro, telephoto, super wide)
- Maximum image quality for professional photography projects
- Industrial inspection with precision optics
- Aerial/drone photography with Raspberry Pi
FAQ
Is IMX477 compatible with Jetson Nano?
IMX477 is not officially supported by Jetson Nano’s JetPack drivers. Arducam provides custom drivers for IMX477 on Jetson Nano as a separate package. IMX219 is the officially supported sensor.
Can I use both cameras simultaneously on Raspberry Pi?
Raspberry Pi 5 has two CSI ports supporting dual cameras simultaneously. You could run IMX219 and IMX477 at the same time for different capture tasks (e.g., wide-angle tracking + telephoto detail).
What lenses work with IMX477 HQ Camera?
Any C-mount or CS-mount lens. Popular choices in India: 6mm CS-mount wide angle (Rs 1,500-2,000), 25mm C-mount standard (Rs 2,000-3,000), 50mm C-mount telephoto (Rs 3,000-5,000). Available from Lamington Road, Mumbai or online from local CV camera dealers.
Does IMX477 support RAW capture?
Yes. Both IMX219 and IMX477 support RAW (Bayer pattern) capture via libcamera’s --raw option. IMX477 RAW files are DNG-compatible and processable in Adobe Lightroom or darktable for maximum quality.
