Raspberry Pi announced the launch of Raspberry Pi Camera Module 3. Four different variants of Camera Module 3, In reality, there are four different variations of Camera Module 3, with prices beginning at $25. They created Camera Modules with choices for infrared and visible light sensitivity, as well as a regular or wide field of view (FoV). Additionally, Camera Module 3 has powered autofocus, which many of you have requested, in place of the fixed-focus optics of its predecessors, enabling you to capture clear photographs of things from around 5 cm away to infinity. A video demo is located lower down the page.
The back-illuminated IMX708 sensor, created in collaboration with Sony, offers better resolution (12 megapixels), a bigger and more sensitive pixel architecture, and compatibility for high-dynamic-range photography.
The first official Raspberry Pi attachment was the Camera Module. It debuted in 2013 and became popular right away. Later on, in the same year, the NoIR infrared-sensitive model was released. After being introduced in 2016 and selling two million units, Camera Module 2—built on Sony's eight-megapixel IMX219 sensor—became our longest-lasting flagship product.
IMX708 offers a 46082592 (11.9 megapixel) array of 1.40m pixels in comparison to IMX219's 32802464 (8.1 megapixels) array of 1.12m pixels. The 16:9 aspect ratio enables us to shoot HD video that utilizes the whole sensor area, and the bigger pixels and more up-to-date pixel architecture translate into higher sensitivity and better low-light performance. The higher horizontal resolution suggests the capacity to photograph finer details.
Every camera module we've created so far has used fixed-focus optics, which are a set of physically static lenses that are designed to focus at infinity but can also provide pretty good images of things that are as near as a meter away.
For the first time, powered autofocus functionality is introduced in Camera Module 3. The lens assembly is supported by a voice-coil actuator that enables us to move it backward and forwards in relation to the sensor until the scene's chosen region—typically the middle—is sharply focussed. Brian is here with a brief demonstration.
By measuring the photons that strike each pixel over the course of an exposure period, an image sensor captures a picture. The choice of exposure length is crucial: for a bright scene, we want a short exposure to prevent oversaturating the sensor and blowing out the image, while for a dark situation, we want a long exposure to catch features that are poorly lighted with the greatest possible signal-to-noise ratio.
All Raspberry Pi computers with CSI ports, with the exception of the Raspberry Pi 400 and the Zero launched in 2016, are compatible with Camera Module 3. The board's dimensions and mounting hole locations match those of Camera Module 2. The sensor module has changed in size and location, making it mechanically incompatible with the camera cover for the Raspberry Pi Zero Case.

Make sure you have the most recent version of the software before you start because only the most recent release has support for autofocus. The new Camera Module 3 is only supported by the contemporary libcamera software environment and by the libcamera-based Picamera2 beta under Raspberry Pi OS Bullseye. But don't worry, the new hardware and software documentation, as well as the documentation for our Picamera2 library, will get you up and running.
