Huh

We have found a malfunction in the firmware ver.4.20 launched on December 17 2015, which rarely causes freeze when shooting in AF-C mode. So we will suspend the disclosure of this firmware right away.

FUJIFILM North America Corporation is excited to announce the new FUJIFILM X-T1 IR (Infrared), the first advanced infrared X-Series mirrorless camera that delivers high performance in demanding fields for technical experts, law enforcement, medical research and scientific communities. Sharing nearly identical specifications as the award-winning FUJIFILM X-T1, the FUJIFILM X-T1 IR adds advanced infrared technology to see light from the ultraviolet (UV), visible and infrared (IR) portions of the light spectrum (approximately 380nm – 1,000nm). The X-T1 IR is a premium mirrorless camera specifically designed for professionals, and pairs seamlessly with each high quality FUJINON XF lens for reliable and outstanding results.

FUJIFILM X-T1 IR (Infrared)

The FUJIFILM X-T1 IR builds on the performance and capabilities of the original X-T1, and with its new infrared technology, delivers dependable results to experts who have a wide range of work requirements, including: crime scene investigation, fine art photography, healthcare diagnostics and observation, and other scientific and technical applications. Infrared imaging is critically important in these fields because it allows users to see information that is not visible to the human eye.

X-Series performance for special applications

Experts, professionals, and practitioners can use the new FUJIFILM X-T1 IR in their everyday work, and immediately benefit from its X-Trans CMOS II Sensor, its ultra wide "Real Time" EVF, and its large, high resolution tilting screen. The X-T1 IR maintains the 100% silent electronic shutter of the X-T1, and its electronic viewfinder allows perfect night vision with an infrared light source, normally invisible to the human eye. The exterior of the X-T1 IR is constructed of 100% magnesium alloy, and is built to be weather-resistant, perfect for use in hot or cold, wet or dusty, and other challenging weather conditions. The X-T1 IR has approximately 80 points of weather sealing for outdoor dependability, and can withstand freeze temperatures down to 14°F (-10°C).

The X-T1 IR focuses on both excellent image quality as well as delivering incredible speed. It uses an extremely fast and accurate autofocus system, and is compatible with Ultra High Speed UHS-II SD memory cards. At up to 8 frames per second, the X-T1 IR is fit for any specialized workplace in need of first-rate photo quality, durability and performance.

v4.0 firmware announcement

Firmware release date - Late June, 2015

1. A new auto focus system with Zone and Wide/Tracking modes for effortless capture of moving subjects. The auto focus system complements the fast and accurate single-point auto focus system with new Zone and Wide/Tracking modes, which use 77 autofocus points across a wider area to substantially improve the camera’s ability to track and capture moving subjects.
   The Zone mode allows users to choose a 3x3, 3x5 or 5x5 zone from the 77-point auto focus area. When combined with the AF-C continuous focusing mode, the camera continues tracking a subject in the selected zone. The 3x3 and 3x5 zones at the center, in particular, offer extra-fast focusing with the use of the built-in phase detection pixels.
   In the Wide/Tracking mode, the camera displays the area in focus, identified automatically out of the 77-point auto focus area (Wide in the AF-S mode) and tracks the focus area’s subject across the entire 77-point AF area (Tracking in the AF-C mode). This makes it possible to maintain focus on a subject that moves vertically, horizontally, and back and forth.

2. Improved auto focus accuracy - Single-point auto focus now divides the focus area into smaller sections to more accurately determine the distance to the subject for even greater focusing accuracy. The built-in phase detection pixels have increased sensitivity from 2.5EV to 0.5EV. This improvement delivers phase detection auto focus performance that enables fast focusing in low-light conditions and on low-contrast subjects.

3. Eye detection auto focus - The new firmware update provides Fujifilm's Eye Detection auto focus, which automatically detects and focuses on human eyes. The function allows you to easily focus on the eyes even in difficult conditions, e.g. when shooting a portrait wide open to obtain a beautiful bokeh background.

4. Auto Macro mode - The firmware update introduces an Auto Macro function that automatically switches the camera into the Macro mode while maintaining the conventional auto focus speed. You no longer have to press the Macro button to initiate a close-up shot. This update eliminates the Macro function assigned to the Macro Button, allowing you to assign a different function to the button.

5. Auto focus improvement in Movie mode - The optimized algorithm delivers a more natural and smooth auto focus action during movie recording.

6. Other improvements

   • Improved Shutter Speed Dial operation - When the Shutter Speed Dial is set to T, you can use the command dial to set the full range of exposure times. This means you can change the shutter speeds across a broader range without having to change camera position. This is particularly useful when shooting in the portrait orientation with the Vertical Battery Grip VG-XT1 attached.
   • Exposure Compensation control in Manual mode - The Exposure Compensation dial can be used to make exposure adjustments while shooting in the Manual exposure mode with the ISO Auto setting.
   • Finer lines on the framing grid enhances visibility - The lines on the framing grid have been made finer making it easier to view the subject.

v3.10 firmware for the X-T1:

• Improvement of the flash function when "MECHANICAL+ELECTRONIC" is selected. An external non-TTL flash will fire when the "MECHANICAL+ELECTRONIC" is selected in the "SHUTTER TYPE" option of the SHOOTING MENU. If "S (Shutter-Priority)" or "M (Manual Exposure)" mode is selected, set the shutter speed to 1/180 sec. or slower.
• Improvement of the Wi-Fi function when "FUJIFILM PC AutoSave" is used. The phenomenon is fixed that Wi-Fi communication with "FUJIFILM PC AutoSave" stops at the moment the LCD turns off.
• Improvement of the display for the "USB MODE" in the SET-UP menu.
  1. When "PC SHOOT FIXED" is selected, the warning of "IMAGES ARE NOT SAVED IN THE CARD" appears.
  2. In case that "PC SHOOT FIXED" is selected in the "USB MODE" and the camera is not connected to a PC via a USB cable, you cannot turn off the camera when you turn the ON/OFF switch to the OFF position or remove the lens from the camera because the camera stays in the waiting mode for image transfer. With this upgrade, the message 'Waiting for the image transfer' will appear to confirm whether you stop the image transfer to the PC or not in such operations. If you press "OK" button, the camera will turn off without recording images
