40x optical zoom
The SX800 is equipped with a 40x optical zoom lens that covers a broad range of focal lengths from 20mm on the wide angle end to 800mm on the telephoto end. It is complemented with 1.25x digital zoom to achieve long-range surveillance equivalent to 1000mm in focal length.
High-performance image stabilization
New image stabilization system
The SX800 combines optical image stabilization (OIS) and electronic image stabilization (EIS) to accurately compensate for camera shake, typically caused by gusts and footing vibrations at the site of camera installation. The system is particularly effective when shooting in the ultra-telephoto range, which is susceptible to even the slightest of shakes.
In the EIS mode, the SX800 uses a sensor large enough for its lens’s effective diameter to secure full HD resolution (1920 x 1080), thereby delivering footage of premium quality. The combined use with OIS also improves the durability of the image stabilization system substantially.
Use of new devices
The SX800 sports high-precision gyro sensors to accurately detect minute vibrations that could not be detected previously. The use of newly-developed high-thrust linear motor delivers an advanced level of accuracy and tracking performance.
New ceramic bead roller system
The SX800’s OIS uses a unique “ceramic bead roller” system. Ceramic beads, processed in ultimate precision, minimizes friction and resistance to achieve advanced responsiveness and excellent durability in image stabilization.
High-speed AF system
On-sensor phase detection AF
The on-sensor phase detection AF uses phase detection pixels across the sensor to instantaneously measure distance according to the displacement of incident lights. The SX800 also offers “contrast AF,” which detects areas of high contrast in images at high accuracy, and automatically switches to the optimum AF setting.

Rear Focus mechanism
The use of the Rear Focus mechanism has significantly reduced the weight of the focusing lens group. This has also dramatically increased the focus drive speed to enable “continuous AF.” Users can choose between “Continuous AF,” “Quick AF” and “Manual Focus” according to the conditions where the camera is used.
Image processing technology
Low light conditions
Heat Haze reduction
The SX800 uses a unique image processing technology to reduce the shimmering effect of heat haze, caused by large difference in atmospheric temperatures, to make the entire images easier to see.
Cameras with built-in lens
Conventional surveillance systems require the adjustment of optical axis and flange focal length when mounting a lens on a camera. The SX800, which carries a built-in lens, is shipped with such settings optimally adjusted to bring out maximum performance. The design also eliminates the need for complicated wiring, thereby significantly reducing man-hours at the time of installation.
New design with advanced rigidity and portability
The SX800’s aluminum extrusion body is highly rigid and exceptionally robust. A carrying handle* may be attached to the body, using screw holes at the top, for transporting convenience.
* FUJIFILM does not offer a carrying handle.
