![]() ![]() ![]() I would be very interested in seeing the same comparison photos but with the focus appropriately set on the V2 module, or even better, it would be good to see comparisons in low-light performance from the new module due to the increased bit depth (I think? I haven't fully read the specs) and sensor size.Arduino have launched an upgrade to their 8-bit Arduino UNO R3 board with the Arduino UNO R4 featuring a 48 MHz Renesas RA4M1 Arm Cortex-M4F 32-bit microcontroller, and an optional ESP32-S3 module for WiFi 4 and Bluetooth 5.0 connectivity. The main difference in the comparison photos shown in the article seems to be the focus, and seem to give the impression that the only way to do close focal work is to use the new camera, but this is not the case. Earlier models of the camera (and most third-party clones) have the focus fixed with a dot of glue (even these can be adjusted with enough effort, though I wouldn't want to suggest everyone do that - it's definitely worth just grabbing a V2 camera) but the V2 Pi Camera module is a lot easier to adjust the focus of one that I purchased (and one that a friend purchased) even came with a small wrench to adjust it easily. I've noticed this post talks a lot about the ability to focus the lens on the High Quality Camera, and the inability to do so on the V2 Pi Camera, however you can change the focus on the V2 Pi Camera. A manually controlled focus means that we can compose our shots and focus in on specific areas and blur out the rest of the shot for that professional look. With the Raspberry Pi High Quality Camera, we see much sharper images with rich colors. ![]() But for less than $30 (sometimes less than $10) what did we expect? But this required a special tool to rotate, otherwise you'd risk scratching the lens. Color reproduction was poor and image quality was grainy. Version 2 of the Raspberry Pi Camera Module did feature a focus ring to alter the focus of the camera. With a fixed focus lens, the subject had to be brought to the lens and composition was cramped. The previous camera modules provided a decent entry into photography with Raspberry Pi, but they images that were at best “good”. Image Quality of the Raspberry Pi High Quality Camera Enhanced functionality for the Raspberry Pi High Quality Camera is still a little way off yet, developers are working to make this happen. At the time of writing the Picamera library has basic functionality and can record 1080p video and 5K images, and also manipulate the images on the fly. With Picamera we can trigger the camera to take an image / video using sensors and inputs connected to the GPIO. Images are typically saved as JPG, but we can also select RAW, GIF, BMP, PNG, YUV420, RG8888 file formats.Īnother way to capture images and video is via the Picamera Python module which enables the camera to be used in projects powered by the popular programming language. The Raspberry Pi High Quality Camera’s maximum resolution is 4056 x 3040 pixels (5K) and this produces an image of around 6MB in size. To test the focus of the camera we ran raspistill with the -k switch, which enabled us to set the focus of the lens. The first time we take a picture with any official camera, we use raspistill, Raspbian’s built-in capture command, which can quickly show if the camera is connected and working as expected. ![]()
