The Ambitious Sitina 1 Open-Source Camera Update

The Sitina 1 open-source camera update is an innovative endeavor aimed at creating a full-frame mirrorless camera. Developed by engineer Wenting Zhang, this project has grown from its initial concept of converting an analog SLR camera into a sophisticated digital version. The result is a versatile camera with an active E-mount, allowing interchangeability of lenses and a variety of photographic possibilities. As the project evolves, it garners attention from photography enthusiasts and tech-savvy users alike.

Project Overview

Originally, the Sitina 1 began as an exploration into digital photography. Wenting Zhang’s vision has transformed it into a fully-fledged mirrorless camera that far exceeds its initial purpose. This transformation highlights the ingenuity and creativity within the DIY community, particularly for those interested in photography. This ambitious project aims not only at enhancing personal experiences but also at democratizing access to advanced photographic technology.

Hardware Specifications

The hardware of the Sitina 1 is meticulously designed to cater to photography enthusiasts who appreciate quality and flexibility. Here are some vital hardware components:

System-on-Chip (SoC)

At the heart of the Sitina 1 is the Xilinx Zynq 7010. This SoC features dual Cortex-A9 CPU cores that run up to 667MHz. It also packs a 28K logic cell FPGA, ensuring efficient processing power for swift image capture and processing.

Memory and Storage

The Sitina 1 is equipped with 512MB of 16-bit DDR3 SDRAM. This memory allows for smooth operations and quick data processing—crucial for capturing high-resolution images. Additionally, the camera features various external ports, including an SD slot, USB Type-C, and a flash sync terminal for enhanced functionality.

Image Sensor

One of the most critical components of the Sitina 1 is its image sensor. It utilizes a Kodak/ONsemi KAI-11000/KAI-11002M/CM, a 35mm Interline CCD sensor. This sensor measures 36.0 x 24.0 mm and boasts an effective resolution of 10.7 megapixels. The sensor’s size and capabilities contribute significantly to the high-quality output of the camera.

Display and User Interface

The camera features a 3.4 inch 480×480 high brightness DPI IPS LCD. This display provides clarity and high visibility in various lighting conditions, making it easier for photographers to compose their shots.

Camera Features

The features offered by the Sitina 1 enhance its usability and adaptability. Photographers can appreciate several vital specifications:

Image Resolutions

The camera supports multiple still image resolutions, including a maximum of 4008×2672 pixels, effectively allowing for 10.7MP images. There are crop options available that reduce the resolution down to 5.6MP, providing users the freedom to choose based on their needs.

File Formats

Photographers will find the image formats supported by the Sitina 1 impressive. It captures images in DNG format, which offers lossless compressed RAW options of 10, 12, or 14 bits. JPEG is also supported, catering to users who prefer immediate usability without extensive post-processing.

Performance Specifications

The readout speed of the Sitina 1 reaches up to 5 frames per second at its highest resolution. The ISO range extends from 100 to 6400, allowing for excellent performance in low-light situations. However, it should be noted that video recording is not currently supported.

Recent Updates

Wenting Zhang has been actively enhancing the Sitina 1 open-source camera update. Significant improvements include upgrades to the power management system. The live view display frame rate has been increased from 3fps to an impressive 14fps, enabling smoother operation. Furthermore, image magnification has been implemented, which greatly benefits manual focusing—a critical feature for precision photography.

The Open-Source Nature

One of the standout aspects of the Sitina 1 project is its open-source framework. This initiative allows photographers and developers access to the hardware design, software source code, and schematics. Users can find these resources on GitLab, all under permissive licenses. The firmware and gateware are provided under the MIT license, while the hardware is available under the CERN Open Hardware License Version 2. This openness encourages collaboration and innovation within the community. For more details, visit Digital Camera World or refer to Gigazine.

Assembly and Customization

Building the Sitina 1 requires a certain level of technical know-how. Advanced electronics and programming skills are essential. Moreover, a 3D printer is necessary for creating the physical casing. Wenting Zhang provides comprehensive assembly videos and step-by-step instructions for those eager to construct their own camera. This accessibility empowers aspiring photographers and tech enthusiasts to engage on a deeper level.

Developer’s Motivation

Wenting Zhang’s drive behind the Sitina 1 stems from a passion for DIY photography and electronics. While he acknowledges the project’s time-consuming and challenging nature, his enthusiasm is palpable. By creating this camera, he not only fulfills a personal goal but also inspires others to explore the world of photography in an innovative way.

Conclusion

The Sitina 1 is more than just a camera; it represents creativity, innovation, and community collaboration in the world of digital photography. With its impressive specifications and open-source nature, it encourages personalization and technical exploration. As the project continues to develop, it invites photographers and tech enthusiasts alike to engage with cutting-edge technology, making photography more accessible and enjoyable for all.
