The 5th anniversary of Panasonic Quan Huafu： the evolution from initiative to excellent stability.

　　　As one of the leading brands in the camera industry, Panasonic has made continuous innovation and progress in the field of anti-shake technology, especially in the full-frame camera series, from the initial optical anti-shake to the advanced fuselage anti-shake technology, and has always been committed to providing users with a more stable shooting experience. This paper will deeply analyze the historical evolution and important nodes of anti-shake technology of Panasonic full-frame camera.

　　Panasonic has a profound heritage and a number of patented technologies in anti-shake technology, and its anti-shake systems are mainly divided into two categories: O.I.S.-Optical Image Stabilizer and B.I.S.-body image stabilizer/in-body image stabilization. In fact, Panasonic has embedded optical anti-shake technology in many of its lens products, which offsets camera shake through the floating lens group inside the lens, thus improving the stability and clarity of hand-held shooting. This technology is suitable for still photography and video shooting, especially in long-focus shooting and low-light environment.

　　In terms of camera body anti-shake, Panasonic started its layout from Quan Huafu. In full-frame cameras such as LUMIX S series, Panasonic adopted camera body anti-shake technology to compensate camera shake by moving sensors, especially in lenses without built-in optical anti-shake. This anti-shake technology can work with some compatible O.I.S lenses to realize the so-called dual anti-shake (dual I.S. or Dual I.S. 2), and further enhance the anti-shake effect.

　　Panasonic’s innovation in the field of anti-shake also includes an adjustable anti-shake mode to adapt to different shooting scenes, such as still shooting, video shooting and even motion tracking shooting. The anti-shake system of Panasonic camera is considered to be the industry leader, providing users with a stable shooting experience and high-quality image output.

　　Origin and infrastructure (before 2006)

　　As early as entering the interchangeable lens camera market, Panasonic has realized the importance of anti-shake technology. Although it is impossible to accurately point out the origin of Quan Huafu anti-shake technology in the existing information at a specific time, it is certain that Panasonic introduced optical anti-shake technology into M4/3 system around 2006, and its research and application on anti-shake has begun to accumulate valuable experience.

　　Exploration of optical image stabilization (2006-2019)

　　Since Panasonic announced the development of the first interchangeable lens camera with anti-shake function in 2006, its optical anti-shake technology has been widely used in subsequent product iterations. In 2008, Panasonic released the first micro camera LUMIX DMC-G1. Although the released LUMIX DMC-G1 does not have (IBIS) image stabilization in the body, it can use the lens with Optical Image Stabilizer (O.I.S) function to achieve the anti-shake effect. This means that when users use Panasonic lenses that support optical anti-shake, the optical elements inside the lens will be adjusted in real time according to the camera vibration, reducing the blur caused by hand shake, thus improving the clarity of photos and videos.

　　Subsequently, in 2009, Panasonic FX33 adopted the optical anti-shake function, which effectively reduced the blur caused by shaking during hand-held shooting. During this period, Panasonic’s optical anti-shake system gradually matured and improved in many consumer and professional camera products. At this time, the concept of "double-effect anti-shake" came into being.

　　Crossing the threshold of fuselage anti-shake (2019)

　　In 2019, the release of Panasonic LUMIX S series full-frame cameras LUMIX S1 and LUMIX S1H marked a major breakthrough in Quan Huafu anti-shake technology. Among them, LUMIX S1 is equipped with the in-body image stabilization (IBIS) system for the first time, which compensates the jitter through the movement of the sensor, greatly improving the stability under various shooting conditions. This measure not only enhances the camera’s shooting ability in low light environment, but also provides a more stable picture for telephoto shooting and video recording.

　　·Active I.S technology and Quan Huafu optimization (after 2020)

　　Over time, Panasonic continued to develop and improve its anti-shake technology, especially in full-frame cameras. With the application of Active I.S. technology, Quan Huafu sensor can also achieve excellent anti-shake effect. Even in the face of the challenges brought by larger sensors, Panasonic can still achieve high-level anti-shake performance through precise algorithm and mechanical design.

　　Panasonic Active I.S is an advanced optical anti-shake technology developed by Panasonic for its digital cameras and camcorders, which belongs to an enhanced version of Panasonic Optical Image Stabilizer (O.I.S.) technology. Active I.S is mainly designed for a specific dynamic shooting environment, such as extreme hand-held instability, or a higher level of anti-shake compensation is needed when shooting fast moving objects.

　　Active I.S provides a more powerful compensation mechanism, which can effectively reduce the picture jitter in a wider range and more complex vibration frequency, and ensure that a clearer and more stable image can be captured when shooting video or still photos, especially when using a slow shutter speed. This technology is especially suitable for shooting moving scenes, such as shooting while walking, chasing the moving subject and other difficult situations, which enhances the photographer’s creative freedom and success rate under various complex conditions. With the development of camera technology, Active I.S. is often combined with other anti-shake technologies such as Dual I.S to form a more comprehensive and efficient anti-shake solution.

　　Advanced anti-shake and industry leading (until 2024)

　　In recent years, Panasonic LUMIX full-frame cameras, such as LUMIX S5 series, have made remarkable achievements in fuselage anti-shake, which not only has high-precision five-axis anti-shake function, but also works with optical anti-shake of compatible lenses to achieve Dual IS 2 anti-shake effect.

　　Dual IS 2 technology is an upgraded version in which the two anti-shake methods, body anti-shake and lens anti-shake, work together. It can intelligently detect and compensate the camera shake in five axes (up, down, left and right scrolling and translation) by using the anti-shake components of the body and lens at the same time. This two-pronged anti-shake system can achieve a more significant stabilization effect than using the fuselage or lens alone, especially when the shutter speed is slow or shooting a long focal length lens, which can help users get clearer and more stable images. After updating to Dual IS 2 version, the anti-shake performance of Panasonic camera system can usually reach a higher number of compensation files, for example, up to 5 files or more, which is especially beneficial for low-light photography and video shooting. The latest LUMIX S5M2 model has improved anti-shake performance and intelligent design, which enables photographers and cameramen to enjoy unprecedented stability and convenience in both static photography and dynamic video creation.

　　The evolution history of Panasonic full-frame camera anti-shake technology is a story full of innovation and practice. From the basic construction of optical anti-shake, to the refinement and optimization of fuselage anti-shake technology, to the advanced anti-shake solution combined with modern photography needs, Panasonic has always been at the forefront, setting a high standard for the industry and continuing to lead the future development of anti-shake technology.
