A fast autofocus performance speed of 0.08 seconds is also enabled using the advanced Intelligent Hybrid AF system using both contrast- and phase-detection focusing methods.
Intelligent Hybrid AF and Enhanced Manual Focus
Intelligent Hybrid AF is a quick, responsive autofocus system that employs both contrast- and phase-detection methods to acquire focus quickly in a wide variety of lighting conditions and shooting situations. Clear focus can quickly be attained to aid in catching fast-paced movement more easily. Three focus modes are available (AF-S, AF-C, and M) for greater control over how the X-T1 achieves sharp focus. When working with autofocus, the AF area is divided into a 49-point matrix in order to gain clear focus of any type of subject matter. Additionally, a built-in AF assist lamp is available for aiding the focus system when photographing in low-light situations.
When working with manual focus, two additional features can be employed for enhanced critical focusing in a more controllable manner. By using the phase-detection pixels located on the imaging sensor, Digital Split Image technology is able to assist in acquiring precise focus through the implementation of four striped focusing aids; akin to a rangefinder focusing method, once these stripes have been lined up, sharp focus can be ensured. Also contributing to manual focus accuracy, Focus Peak Highlight has been integrated and enables a more objective system of focusing by way of highlighting sharp edges and lines of contrast, using one of three colors, once they are in focus.
Multi Mode Real Time Viewfinder
An advanced electronic viewfinder has been incorporated into the X-T1′s design to support clear eye-level monitoring along with a host of unique viewing features to better support a more efficient overall workflow. The Real Time Viewfinder is comprised of a 2,360k-dot OLED display and features an exceptionally high magnification of 0.77x, along with a 31° angle of view. This perspective is further complemented by the 0.005 sec. lag time, which smoothly and seamlessly renders scenes and moving subjects.
Beyond the technical aspects of the viewfinder, an adaptable graphical user interface has also been designed to increase efficiency during shooting. Four different viewing modes are available:
FULL: This mode takes advantage of the high magnification ratio of the viewfinder and produces an image that fills the majority of the viewfinder in an unobstructed manner. Shooting information is presented at the top and bottom edges and does not interfere with the image frame itself.
NORMAL: This mode enables you to focus on the composition at hand while still having an in-depth understanding of camera settings and shooting conditions.
VERTICAL: When the camera is held in a vertical orientation, the information display automatically rotates so it is facing upright for easier reading of camera settings. When working in this mode, images can also be reviewed in the vertical orientation.
DUAL: Serving to benefit those working with manual focus, this mode presents a split screen view of the scene where you see both a regular view as well as the Focus Assist View (Focus Highlight Peaking and Digital Split Image) at the same time, allowing you to concentrate on the image composition as well as critical focus accuracy.
In addition to the four viewing modes, the shooting information displayed within the viewfinder can also be customized to suit one’s needs. 19 different settings can be toggled on or off depending on preference.
Classic Camera Design
Featuring a body design reminiscent of SLR film cameras, the X-T1 exhibits a meshing of both analog exposure controls along with intelligent automated technologies. The clean and functional body design incorporates physical shutter speed, ISO, drive mode, AF mode, and +/- 3 EV exposure compensation double-deck precision-milled aluminum alloy dials that pair well with the manual aperture rings found on many of the XF lenses for intuitive exposure setting selection. Depending on individual needs, six customizable buttons, dual command dials, and an easily-accessible Q Menu provide an efficient solution for modifying some of the most frequently used camera settings, such as ISO, white balance, and file settings. For more extensive menu navigation, as well as live view monitoring and image review, a 3.0″ 1,040k-dot LCD monitor is available and features a tilting design to better support working from high and low angles.
Furthermore, the magnesium alloy body also features approximately 80 points of weather sealing to protect itself from dust and moisture, as well as temperatures as low as 14°F, for confident use in trying conditions.

Full HD 1080p video recording is supported up to 60 fps, with other frame rates and formats also available. Full-time AF tracking is available during recording with subject tracking capabilities for ensured sharpness when either the subject is moving or if the camera is moving, panning, or zooming. +/- 2 EV exposure compensation is available during recording as well as the use of Film Simulation settings.
An HDMI port enables high definition playback of movies to an HDTV and the inclusion of a 2.5mm input supports the use of an optional external microphone for enhanced sound quality.
Built-In Wi-Fi Connectivity
Wireless connectivity is built into the camera and allows for instant sharing of images directly to an Android or iOS mobile device. The Fujifilm Camera Remote app allows you to browse the image contents of your camera from your mobile device and transfer both videos and photos, and the entire sharing process is further expedited by simply pressing and holding the dedicated Wi-Fi button to begin transferring immediately. Remote camera control and monitoring is also supported through the use of the app, which enables Touch AF, shutter release, exposure settings adjustment, Film Simulation modes, white balance modes, macro, timer, and flash controls to all be adjusted from the linked mobile device. Location data can also be embedded into image file’s metadata for geotagging.
Film Simulation Mode and Advanced Filters
Taking advantage of Fujifilm’s vast history in traditional film-based photography, the X-T1 integrates several Film Simulation modes to mimic the look and feel of some Fujifilm’s classic film types. Pulling from their line of transparency films, PROVIA offers natural-looking tones for everyday shooting, VELVIA produces a more dramatic and rich tonality with deeper color saturation, and ASTIA gives less contrast for a softer depiction of skin tones. Mimicking their negative films, PRO Neg. Std. gives smooth image tones that are suitable for accurate color renditions, while PRO Neg. Hi produces a more dramatic feel with the ability to draw color out of a variety of lighting conditions. In addition to the colorful benefits of these Film Simulation modes, there are also monochrome modes that simulate the look of traditional yellow, green, and red black and white contrast filters. A sepia mode is also available for producing an inherently nostalgic look.
Eight Advanced Filters are also available to creatively enhance the look of imagery, and include: High Key, Low Key, Soft Focus, Toy Camera, Miniature, Pop Color, Dynamic Tone, and Partial Color (Red, Orange, Yellow, Green, Blue, Purple).
