Fujifilm X-T1 firmware version 4.0 advanced autofocus manual
Features
The new AF system in the Fujifilm X-T1 and X-T10 adds Zone and Wide/Tracking options to the existing 49-point Single Point mode. This improves focus performance when shooting moving subjects and helps you to capture perfect photos when the subject is moving across the 77-point AF area. Zone mode allows users to choose a 3×3, 5×3 or 5×5 zone from the 77-point AF area. When combined with the AF-C continuous focusing mode, the camera tracks a subject in the center of the selected zone. In the Wide/Tracking mode, the camera displays the area in focus, identified automatically out of the 77-point AF area, and tracks the subject across the entire 77-point AF area. This makes it possible to maintain focus on a subject that moves up/down, left/right or closer/further from the camera. The new AF system makes it easier than ever to capture moving subjects, dramatically increasing your shooting options.
UI enables easy framing
The user interface of the Fujifilm X-T1 and X-T10 has been carefully designed to make it comfortable to shoot while looking through the viewfinder. Most frequently used shooting data, such as the remaining number of shots, shooting mode, shutter speed, aperture, exposure compensation and ISO sensitivity, is displayed outside live view. You can select the icons and information settings to display to ensure a clear live view image that allows you to concentrate on following the subject, selecting the AF frame and framing your shot.
Easy-to-use Focus Area Selection screen
The Focus Area Selection screen displays 49 points in the Single Point mode or 77 points in the Zone and Wide/Tracking modes. In the 77-point view, Intelligent Hybrid AF using the high-speed phase detection AF system is activated for the 3×3 and 5×3 zones at the center, where the phase detection pixels are embedded. The position of the focus area, the size of the AF frame and the starting point of focus tracking in AF-C can be adjusted in applicable AF modes.
AF Technology
AF technology in the X-T1 / X-T10
The AF system incorporates some new technologies.
These include Zone and Wide/Tracking modes with enhanced tracking performance on moving subjects, as well as innovative technologies such as Eye Detection AF for accurate portrait
and Auto Macro that eliminates the need to switch manually to the Macro mode.
The algorithm has also been optimized to improve AF in many areas including improved precision in Single Point AF and enhanced performance during movie shooting.
Choose from the fast and precise 49-point Single Point mode or the Zone and Wide/Tracking modes, which helps capture moving subjects traveling across the 77-point AF area. Each of them can be combined with AF-S and AF-C to offer a total of six AF modes.
Face Detection + Eye Detection AF
Face Detection detects human faces while Eye Detection AF automatically detects the location of human eyes allowing you to focus quickly even when shooting with a wide aperture for shallow depth-of-field. You can specify either the right or left eye to focus on.
Highly precise Intelligent Hybrid AF
Intelligent Hybrid AF combines on-sensor phase-detection AF with contrast AF. On-sensor phase detection AF uses phase detection pixels on the image sensor for fast and precise focus even in low light conditions or on low contrast subjects. Contrast AF is useful in even darker conditions, delivering particular focus on all types of scenes.
Fast and smooth AF during movie shooting
Intelligent Hybrid AF is even used during movie shooting, switching between the phase detection AF and contrast AF at the center of the screen. The algorithm has been optimized for fast, precise and smooth focusing. When the Face Detection function is activated, the system automatically maintains focus on people during movie shooting.
Fast and accurate Predictive Tracking AF (in AF-C mode)
The advanced Predictive Tracking AF technology, which uses data from the subject to predict its next move, enables highly precise AF-C shooting. Once captured in the AF frame, the camera continues to track the subject even if it makes unpredictable movements up/down, right/left or closer/further, which the conventional AF system had difficulty following.
High-speed AF from macro to infinity
Accurate Single Point AF
The Single Point AF area is divided into smaller sections to accurately determine the distance to the subject for even greater focusing precision. When the selected section contains both subject and background, the AF system focuses on the subject nearer the camera, to prevent accidentally focusing on the environment.
Fast linear-motor-driven AF
Lenses (typically zooms) with an inner focusing mechanism are driven by a linear motor. It operates lens elements in the non-contact state to deliver silent and highly responsive AF. Lenses with a linear motor swiftly respond to the new AF system’s high-speed focusing, further helping to track a moving subject.
The new AF system features an Auto Macro function that eliminates the need to press the Macro button before shooting close-ups. The Auto Macro function delivers optimized AF speed across the range to increase the focusing speed from macro to infinity by approx. 10%.
Focus Mode
AF-S
Single Point Zone Wide/Tracking, Accurately capturing the subject.
AF-S mode locks focus when the shutter button is pressed halfway. When the focus is locked, the camera beeps and makes the Focus indicator icon and AF frame flash green. When shooting continuously, the camera locks focus on the first shot and maintains the focus position on subsequent shots. This fundamental AF mode is used for photographing subjects that don’t move.
AF-S + Single Point
For capturing subjects using a particular AF point, A primary AF mode. Set focus using one of the 49 focusing points – ideal for focusing precisely on a topic in a fixed location. The focus area can be one of the five different sizes, and the location of the focus area can also be changed.
AF-S + Zone
For capturing moving subjects across a large AF area
This mode is suitable for slower moving subjects and snapshots that are difficult to focus with the Single Point mode. You can choose a 3×3, 5×3 or 5×5 zone from the 77-point focus area. The central 3×3 and 5×3 zones offer extra-fast focusing with the use of the on-sensor phase detection AF system.
AF-S + Wide/Tracking
Automatically capturing a subject with unpredictable movements.
An upgrade on the previous Auto Area AF mode, the camera automatically assesses the entire 77-point focus area, selects multiple zones and focuses on the subject. Ideal when shooting a scene with numerous elements, the camera focuses on the subject even within the most complicated scene.
