The Zenmuse X4S is a powerful camera featuring a 20 megapixel 1-inch sensor and a maximum ISO of 12,800. Dynamic range is increased from the Zenmuse X3 by 1 stop, with signal to noise ratio and color sensitivity increased by 1.5 stops for next-level image quality. The Zenmuse X4S uses a DJI-designed compact lens with low dispersion and low distortion 24mm equivalent prime lens. This 84° FOV, high resolution lens makes the Zenmuse X4S as powerful during aerial imaging as it is on the ground.Combined with CineCore 2.0, the Inspire 2’s powerful image processing system, it can record 4K/60 H.264 and 4K/30 H.265 videos at a 100Mbps bitrate, and oversample 5.2K video into 4K video in real-time, capturing fine image details. In Burst Mode, the Zenmuse X4S supports 14fps shooting at 20 megapixels in both JPEG and DNG formats. It is able to make the difficult balance between agility and image quality.
Compared with the Inspire 1, the Inspire 2 utilizes an innovative structure that separates the CineCore 2.0 image processing system from the camera and places it inside the aircraft. This means that the sensor and optical system are detachable and easily connected using a newly designed quick-release connector. Designing the camera system in this way effectively protects the sensor from magnetic interference originating from the processor. It also allows a range of lightweight camera units to be connected as required by different scenes. The Zenmuse X4S has a 1-inch sensor and a compact design. Working in tandem with the CineCore 2.0 image processing system, the Zenmuse X4S makes photo and video capture effortless.
Sensor size is vital to image quality. The Zenmuse X4S’s 1-inch Exmor R CMOS sensor uses large pixels measuring 2.4μm per pixel to create 20 megapixel images and 11.6 stops of dynamic range. Compared with the Zenmuse X3, which uses a 1/2.3-inch sensor, the Zenmuse X4S has an additional stop of dynamic range and 1.5 more stops signal to noise ratio and color sensitivity, as well as a maximum ISO of 12,800, for even more stunning imaging capabilities.
Used with the Inspire 2 CineCore 2.0 image processing system, the Zenmuse X4S records 4K/60 using H.264 and 4K/30 using H.265, both with a 100Mbps bitrate. It also supports oversampling of 5.2K video to 4K, while 3D denoising technology and 3D LUT color reproduction technology retains fine detail in captured images.
The custom-engineered 8.8mm/F2.8-11 lens is compact with low distortion and has a radial dispersion of only 3μm that is equivalent to a 24 focal length on a 35mm camera. Its high MTF rating performance and removal of low pass filters make the Zenmuse X4S an incredibly powerful camera for its size, both in the air and on the ground. The Zenmuse X4S also uses a leaf shutter capable of 1/2000 shutter speeds, eliminating rolling shutter distortion that can occur when taking images of fast moving subjects or when flying at high speed, allowing dramatic shots to be captured more easily.
*MTF chart is used to measure the ability of a lens to transmit contrast and resolve detail. The low line pairs reflect the overall contrast, the high line pairs reflect detail resolution. The Image Height shows the ration of the distance from the current point to the center of the image circle and image circle radius. MTF 1.0 means the perfect performance of a lens.
With the help of the powerful CineCore 2.0 image processing system integrated into the Inspire 2, the Zenmuse X4S is able to shoot JPEG and DNG photos at up to 14fps in Burst Mode as well as take photos during video recording, so that the perfect moment can be captured forever.
A lightweight design combined with high speed processing makes the Zenmuse X4S gimbal motors ultra-reactive. It responds instantly to subtle movements of the airframe and neutralizes it to keep the camera stable. With a precision of ±0.01°, combined with three damping balls and lightweight damping boards that neutralize vibration, footage is completely smooth. As a result of tightly integrated and hidden wires, it is only able to rotate 320° but 360° and beyond is possible by yawing the airframe itself.
The combined stability of the 3-axis gimbal and the Inspire 2 effectively give the Zenmuse X4S a tripod in the sky, making high-altitude 8 second exposures a reality.
