Filmmakers get another 8K-capable mirrorless system camera to choose from, as Fujifilm&s new flagship X-H2 model became official last night. The APS-C camera offers higher sensor resolution (the highest in the X series so far) compared to the X-H2S, as its rear-exposed X-Trans CMOS 5 HR sensor resolves at 40.2 MP. It also features an improved image processing algorithm, according to Fujifilm, which should minimize annoying image noise despite the high resolution.
An advanced pixel structure results in a larger amount of light on the sensor, so ISO 125 is now available as a standard sensitivity and no longer needs to be selected over the extended ISO range. The new sensor is also said to be very precisely controllable, allowing ultra-short exposure times. For example, the fastest shutter speed of the electronic shutter has been increased by 2.5 EV steps from 1/32,000 sec. to now 1/180,000 sec.
8K shooting with no heat limit?
The new sensor coupled with the X-Processor 5 allows recording of 8K video at 30p with 10-bit 4:2:2 sampling. The X-H2&s camera body is said to be designed to quickly dissipate the heat generated by the sensor and processor. Theoretically, it should be possible to record in 8K for up to 160 minutes without interruption (in H.265 4:2:0), depending on the ambient temperature.
When recording in 4K, the camera uses internal oversampling to access the 8K data. Thanks to the high sensor resolution, it is possible to zoom into the image at up to 2x magnification when shooting in 4K.
Like the S model, the X-H2 supports three Apple ProRes codecs: ProRes 422 HQ, ProRes 422 and ProRes 422 LT. When recording video up to 4K resolution, proxy clips (ProRes 422 Proxy) can also be recorded in parallel at a low bit rate. In combination with a compatible external HDMI recorder from Atomos or Blackmagic Design, 12-bit RAW video files can also be recorded. These can be saved as Apple ProRes RAW or Blackmagic RAW in up to 8K resolution at frame rates up to 29.97 frames per second.
In addition to F-Log, the X-H2 also supports F-Log2, which, according to the manufacturer, offers an extended dynamic range of more than 13 stops and thus more leeway in video editing.
Improved autofocus, IBIS stabilization
The 40.2-megapixel sensor has more phase-detection pixels than previous X-series models, which is said to result in even more precise focusing in AF-S mode, and the X-H2 (like the X-H2S) also features a new AF algorithm for predicting object movement, enabling even more reliable focus tracking in continuous focus (AF-C). Developed using Deep Learning technology, the algorithm not only detects and tracks people&s faces and eyes, but also reliably keeps animals, birds, cars, motorcycles, bicycles, airplanes and trains in focus.
The video AF algorithm has also been optimized, and there is also a new focus indicator that makes manual focusing easier when filming and can be used in combination with the focus peaking function.
Like the X-H2S, the FUJIFILM X-H2 is equipped with built-in five-axis image stabilization (IBIS). This enables sharp shots at shutter speeds up to seven EV stops slower.
The X-H2&s electronic viewfinder offers a high-resolution viewfinder image with 5.76 million pixels, 0.8x magnification and a high frame rate of approximately 120 frames per second. The rear touch display resolves to 1.62 million pixels. A customizable AF ON button, a separate video record button, and 3.5mm microphone-in and headphone-out ports are present. The camera&s dual memory card slot supports CFexpress Type B cards in addition to conventional SD cards.
Like the X-H2S, it has a weather-resistant body that is sealed at 79 points to prevent moisture and dust ingress, and is fully operational in cold conditions down to minus 10 degrees Celsius. In addition, the X-H2 (like the X-H2S) is compatible with the FT-XH file transmitter, which allows wired LAN and wireless WLAN tethered video recording. Up to four X-H2s and X-H2s can thus be controlled via a browser application. For example, the recording parameters for each camera can be checked and adjusted, and video recording can be started and stopped synchronously for all cameras. It is also possible to save, copy and load camera settings.
