FUJIFILM Australia has announced the launch of the new Fujifilm SX400, expanding its SX Series of lens-integrated long-range surveillance cameras. The SX400 will be available from early February 2026.
The SX400 is designed for long-range monitoring and inspection in low-light and challenging environments, combining a newly developed F2.8 lens with a compact, lightweight form factor. Fujifilm said the camera is optimised for night-time surveillance, suppressing image noise when sensitivity is increased and delivering clear detail without relying on excessive gain.
The camera supports a 1/1.8-inch effective image sensor and offers a 32x optical zoom covering focal lengths from 12.5mm wide-angle to 400mm telephoto. Despite this range, the SX400 measures just 302mm in length and weighs 3.9kg, making it suitable not only for fixed installations but also for mobile and temporary deployments.
FUJIFILM said the SX400 is aimed at applications such as border monitoring, ports, highways, forest surveillance and infrastructure inspection, where long-distance visibility is required. Its compact design also allows for installation on vehicles and vessels, as well as temporary use at construction sites, disaster zones and event venues where permanent mounting is impractical.
The SX400 features the brightest lens in the SX Series, maintaining an F2.8 aperture from 12.5mm to 200mm. This enables clearer, lower-noise imaging in low-light conditions compared with conventional long-range cameras. Fujifilm’s optical design draws on technologies developed for its broadcast, cinema and GFX/X Series cameras.
Image stability is handled through a combined optical and electronic image stabilisation system, designed to counter vibration from wind, movement or long-distance shooting. The system uses Fujifilm’s ceramic ball roller mechanism to reduce friction and improve responsiveness, supported by high-precision gyro sensors for accurate correction.
Autofocus performance is another focus area. The SX400 uses a rear-focus mechanism with a combination of phase-detection and contrast autofocus, allowing it to lock focus in as little as 0.1 seconds. This helps ensure fast-moving or distant subjects are captured clearly.
For challenging environmental conditions, the SX400 includes heat haze and fog reduction functions. Fujifilm’s image processing reduces distortion caused by temperature differences, airborne particles and haze, helping maintain visibility in conditions that would normally degrade long-range footage.
Installation has also been simplified. By integrating the lens and camera into a single unit, the SX400 removes the need for optical axis alignment, flange-back calibration and chromatic aberration adjustment. Power and control connections are consolidated at the rear of the camera, reducing cabling complexity and speeding up deployment.
The SX400 joins Fujifilm’s existing SX Series lineup, which includes the SX800 and SX1600 models, both widely used for ultra-long-range surveillance. Fujifilm said the SX400 fills a gap for customers needing strong low-light performance and portability without sacrificing zoom range.
