Fujifilm Corporation announced the upcoming release of the “FUJIFILM SX400” (hereinafter referred to as SX400) as a new addition to its “SX Series” of integrated lens telephoto cameras in early February 2026.
The SX400 comes equipped with a newly developed F2.8 lens, the brightest in the series, allowing the camera to efficiently capture light even in low-light shooting environments such as dark places. This reduces the impact of noise caused by increasing sensitivity, allowing you to capture subjects clearly even at night.
What is the FUJIFILM SX400?
The camera also features a 1/1.8-inch effective image size and a 32x optical zoom that covers a wide focal length range from 12.5mm wide-angle to 400mm telephoto, all while being compact and lightweight, with a total length of approximately 300mm and a weight of approximately 3.9kg. In addition to traditional fixed-position applications such as border and port surveillance and infrastructure inspections, the camera is also suitable for a variety of applications, including mobile applications mounted on vehicles and ships, which have seen increasing demand in recent years, and temporary portable surveillance cameras for use at construction sites and event venues.
High-magnification zoom surveillance cameras are increasingly being used for remote monitoring of borders, forests, airports, ports, highways, and other locations, as well as for remote inspections due to the aging of social infrastructure and labor shortages in inspection work. Fujifilm has been marketing the SX Series of integrated telephoto lenses since 2019, leveraging the optical and image processing technologies it has cultivated over many years. The company has expanded its lineup with the release of the FUJIFILM SX800, which features a 40x optical zoom covering focal lengths of 20mm to 800mm, and the FUJIFILM SX1600, which covers a wide angle of 40mm to 1600mm. The SX Series is popular for its high-speed, high-precision AF and vibration-reduction system, which allow it to instantly capture clear images of objects several kilometers away.
Latest optical technology
The SX400 utilizes the optical technology the company has cultivated over the years for its 4K/8K broadcast lenses and cinema camera lenses, and is equipped with a newly developed F2.8 lens, the brightest in the SX series, enabling it to capture subjects in clear, low-noise images even in dark environments such as at night. Furthermore, by developing the lens and camera as a single unit, the size has been optimized, achieving a 32x optical zoom that covers focal lengths from a wide-angle 12.5mm to a telephoto 400mm, and a lightweight, compact body measuring approximately 300mm in length and weighing approximately 3.9kg. This allows for flexible operation, not only in traditional fixed installations, but also in locations where a permanent camera installation is not possible, making it easy to transport.
The company will continue to develop groundbreaking products that meet the needs of users and the market, utilizing the unique optical technology it has cultivated through the development of a wide range of lens products and the cutting-edge image processing technology used in its GFX Series and X Series digital cameras.
FUJIFILM SX400 Primary Features
(1) Combines 32x optical zoom with a compact, lightweight design, measuring approximately 300mm in length and weighing approximately 3.9kg
The FUJIFILM SX400 comes equipped with a 32x optical zoom lens, supporting focal lengths from a wide-angle of 12.5mm to a telephoto of 400mm (horizontal angle of view of 31.8° to 1.0°). Despite covering a wide range of focal lengths, it has a compact and lightweight body with a total length of approximately 300mm and a weight of approximately 3.9kg. In addition to being suitable for stationary operation, the compact and lightweight body makes it suitable for a variety of uses, including installation on vehicles and ships, and building portable monitoring and inspection systems.
(2) The brightest lens in the SX series has been newly developed, providing clear images with minimal noise even at night
The newly developed SX series features the brightest zoom lens with an F2.8 maximum aperture. Its unique optical design maintains a brightness of F2.8 from focal lengths of 12.5mm to 200mm, delivering clear, low-noise images even in dark locations, such as at night.
(3) Uses a proprietary vibration-reduction system to reduce image blur
By adopting Fujifilm’s unique vibration-reduction system that enables coordinated control of the optical vibration-reduction function (OIS) and the electronic vibration-reduction function (EIS), even the most minute vibrations can be instantly captured, reducing image blur caused by shaking of the footing or wind, even when shooting at long distances, resulting in stable video capture.
The vibration-damping mechanism uses a proprietary “ceramic ball roller system.” This minimizes frictional resistance during vibration damping, achieving high responsiveness and excellent durability. Furthermore, the high-performance gyro sensor detects minute vibrations without any time lag and accurately compensates for them.
(4) High-speed, high-precision AF that captures the subject instantly and accurately in as little as 0.1 seconds
The focus group has been significantly lightened by adopting a “rear focus system” that drives the small diameter lens in the rear group at high speed. Furthermore, by combining “on-chip phase detection AF,” in which the phase detection pixels of the CMOS sensor measure the distance to the subject according to the deviation of the incident light and quickly adjust the focus, with “contrast AF,” which detects the contrast of the image and adjusts the focus with high precision, high-speed, high-precision AF of approximately 0.1 seconds has been achieved.
(5) Equipped with heat haze and mist reduction function to provide clearer images
The camera comes standard with an excellent heat haze and mist reduction function. Its unique image processing technology reduces the “shake” of subjects caused by mist caused by water droplets or dust in the air, as well as temperature differences in the air. When used in conjunction with the built-in visible light cut filter, it can capture clearer images even in foggy or misty conditions.
(6) Significantly reduced installation work
Developing the lens and camera as a single unit eliminates the need for adjustments to the optical axis and flange focal length, as well as adjustments to suppress color bleeding (magnification chromatic aberration) that occurs with the lens, thereby streamlining the work before installing the camera. In addition, by consolidating the power supply and operating systems on the back of the camera, complex cable connections are no longer necessary, significantly reducing the amount of work required during installation.
