Fujifilm has announced the impending arrival of new firmware updates for its GFX 50S, X-T3, and X-H1 mirrorless cameras. The updates bring improved in-body image stabilization on the X-H1, 4K HDR and F-Log video for the X-T3, and a new 35mm format mode for the GFX 50S.

GFX 50S

The new firmware for the Fujifilm GFX 50S, version 3.30, is due out by the end of November 2018. Fujifilm says the update adds support for a new 35mm Format Mode when using GF- and H-mount adapters, which crops the center of the sensor to a size of 36mm x 24mm, a makes for a 30.5-megapixel image. The update also improves upon the eye-sensor responsiveness, adds simultaneous deletion of Raw and JPEG files, and supports color adjustments for the EVF and LCD displays.

X-T3

The new firmware for the Fujifilm X-T3 is version 2.00. Set to be released in December 2018, the firmware update brings 4K HDR recording in Hybrid Log Gamma (HLG). HLG footage should simplify the capture of HDR content and should improve post-production capabilities. Fujifilm notes it's only compatible with the camera's 10-bit H.265 (HEVC) mode, and works best when viewed on displays and TVs with HLG format support.

Firmware version 2.00 for the X-T3 also brings simultaneous output of Film Simulation and F-Log footage, meaning it's possible to record in F-Log while viewing the Film Simulation image on an external monitor. Fujifilm says this capability isn't compatible with '59.94P/50P, FHD high speed recording, 4K interframe NR, and HDMI output info display mode.'

Continuing on, the X-T3 will now be compatible with All-Intra and maximum bitrate recording with H.264, up to the maximum bitrate of 400Mbps. Also, movie files will no longer be split when the file reaches 4GB so long as it's being stored to an SD card with at least 64GB of storage. It's also now possible to display color temperature on the EVF and LCD displays in Kelvin.

Newsshooter has shared a video showing off some of the new features of firmware version 2.00 for the Fujifilm X-T3.

X-H1

Last up is the Fujifilm X-H1, which is set to receive firmware version 2.00 in December 2018. The defining feature of this firmware update is the improved image stabilization. Fujifilm says in-body image stabilization will now work better with optical image stabilization in lenses to improve overall stability.

'With an XF or XC optical image stabilized lens, in-body image stabilization worked with 3 axis (up and down / optical axis rotation). The remaining 2 axis (right and left pitch, yaw angle) was controlled by optical image stabilization in the lens," says Fujifilm in its press release. "[Firmware version 2.00] has a new image stabilization algorithm to allow the in-body image stabilization to work in all 5 axis and to achieve more than five-stops (up to the equivalent of 5.5 stops) image stabilization by cooperative control according to the types of frequency and blur amount."

Fujifilm notes lenses must also be updated to their latest firmware to get this compatibility. You can find a full list of up-to-date lens firmware on Fujifilm's website.
