Features & Controls

The Fujifilm X100F makes use of an APS-C sized image sensor that Fujifilm has branded an X-Trans CMOS image sensor It offers 24.3 million pixels of resolution and measures 23.6 by 15.6 mm. The X100F's APS-C image sensor is a similar physical size to its predecessor camera, the X100T, but it has a nearly 50% higher megapixel count.

The X100F includes an updated image processor from its predecessor. The new camera makes use of the X Processor Pro, which Fuji claims provides processing speeds four times faster than the previous version. The X100F can shoot at up to 8 frames per second in continuous shooting mode, and it has minimal shutter lag and shot to shot delays.

The Fujifilm X100F is a fixed lens camera with a prime lens, meaning the lens has no zoom capabilities. It works at one focal length, 23mm (or 35mm at a 35mm equivalent measurement).

You can see the two small handles on either side of the aperture ring of the lens clearly in this photo. Because the aperture ring is so thin, you'll use the handles to change the aperture.

In this top view of the X100F's lens, you can clearly see the aperture ring on the thin lens. It's marked with the numbers and letters. To set the f-stop, you'll align a number (or the A for automatic aperture) with the black mark. (One handle is visible on the far left of the ring in this photo.)

The ring to the outside of the aperture ring with ridges on it is the manual focus ring. Beyond manual focus, the X100F offers single AF and continuous AF. Fujifilm gave this camera a 91-point autofocus system that's a significant upgrade from the X100T.

Because the Fuji X100F doesn't have any zoom capabilities, the lens doesn't extend any farther away from the camera body at any point.

The lens has a maximum aperture of f/2.0, which makes it a fast lens, allowing it to excel in low light and portrait photography. The focus distance of the lens is 3.9 inches (or 10 cm) to infinity.

front dials.jpg
Fuji placed a button, switch, and dial on the upper left corner of the front of the camera. You'll be able to access these controls with your right hand while holding the camera. Once you learn to use these, you can make some fast changes to the operation of the X100F.

The front command dial is on the left side of this photo. You can use it to scroll through stored photos or the tabs on the Menu screen. Depending on the camera settings, you may also be able to change the shutter speed.

The switch on the right of the photo (with the orange line) moves to the right or the left and allows you to switch between viewfinder and LCD modes.

The button below the switch is the function 2 button. You can assign any of more than two dozen camera control settings to this button through the Setup menu.

Flash view.jpgOn the right side of the front of the camera, you'll see the AF-assist lamp, the built-in flash, and the viewfinder window (from left to right).

The X100F's built-in flash unit has a guide number of 4.6 (ISO 100 · m). Its effective range at ISO 1600 is between 1.6 and 29.5 feet.

You can pick from five flash modes: Forced flash, slow synchro, commander, external flash, and suppressed flash. And you have flash exposure compensation settings of between +2 and -2 in 1/3 increments. There are multiple red-eye reduction features too.

focus switch view.jpg

The left side of the camera body has a toggle switch for setting the focus mode for the X100F. It's the same toggle switch as was found on the Fuji X100T. The three options are:

  • M - Manual focus
  • C - Continuous AF
  • S - Single AF

top dials.jpg
The top panel contains several control dials and buttons for the Fujifilm X100F. What you'll notice, however, is that the camera has no traditional mode dial. Instead, you'll twist a series of dials and rings to change the mode in which you're shooting. The X100F's four basic shooting modes are:

  • Program - With both the shutter speed dial (on the camera's top panel) and the aperture ring (on the lens) set to A, you'll be shooting in Program mode.
  • Shutter Priority - With the shutter speed dial set to any setting other than A and the aperture ring set to A, you're in Shutter Priority mode.
  • Aperture Priority - With the shutter speed dial set to A and the aperture ring set to a number other than A, you'll be in Aperture Priority mode.
  • Manual - Set both the shutter speed dial and aperture ring to settings other than A to enter Manual mode.
On the top panel of the X100F you'll see the hot shoe in the center of the panel (on the left side of the above photo). You can attach an external flash unit to the hot shoe.

To the right of the hot shoe is the shutter speed dial, which has an interesting design. The dial itself controls the shutter speed. Each number printed on the shutter speed dial represents the shutter speed in a fraction of a second, meaning the 4000 setting represents 1/4000th of a second. T allows for shutter speeds between 2 and 30 seconds. B is the bulb setting.

If you lift up on the shutter speed dial and then twist it, you can change the setting for the ISO. The ISO dial's setting is visible inside the cutout that you can see in the shutter speed dial. In the photo above, you can see A (for automatic), L (for low), and H (for high) on the ISO dial.

To the right of the shutter speed dial is the shutter button. It's surrounded by the power toggle switch.

The Function 1 button (marked with Fn) is to the right of the shutter button. You can change the setting for this button through the Setup menu.

And below the Fn button is the EV dial, through which you can use settings between +3 and -3 in 1/3 increments. There's also a C setting on the EV dial, which allows you to adjust the EV settings to between +5 and -5 with 1/3 increments. At the C setting on the EV dial, you'll use the command dial on the front of the camera to change the EV setting.

Although this dial is close to the edge of the top panel of the X100F, it stays in place well. When I tested the predecessor model, the X100T, it had a similar placement of the EV dial, and I bumped it out of place accidentally on occasion. The EV dial on the X100F doesn't twist as easily with a soft bump as the previous version did.

LCD screen.jpg
The X100F and X100T both have the same LCD screens. Both screens measure 3.0 inches diagonally with 1.04 million pixels of resolution, yielding a sharp display. You can pick among 11 levels of brightness with the display screen.

The Fuji X100F's Hybrid viewfinder is the same model found with the X100T and the X-Pro2. You frame your scenes using the viewfinder or the LCD screen.

The Hybrid Viewfinder gives you different ways to view the scene through the viewfinder, including either an optical viewfinder mode or an electronic viewfinder mode. The optical viewfinder offers a 0.5x magnification of the scene with 92% scene coverage. With the optical viewfinder on the X100F, you're just looking through the window of the viewfinder, not through the lens, however. Selecting the electronic viewfinder causes a small screen to appear visible through the viewfinder window. This gives you a look through the lens, and you'll see data about the scene when using the electronic viewfinder. The electronic viewfinder has 100% scene coverage and 2.36 million pixels of resolution.

The View Mode button is to the right of the viewfinder window. To the right of the View Mode button is the AE-L/AF-L button to lock the exposure and/or focus.

You can press the View Mode button to the right of the viewfinder window to change the way you're framing the scene. Or you can use the switch on the front of the camera. The different modes are:

  • LCD Only - In LCD Only mode, you can use either the LCD screen or the basic optical viewfinder to frame photos.
  • Viewfinder Only - In Viewfinder Only mode, the LCD will go blank. You can switch between the electronic and optical viewfinder by using the toggle switch on the front of the camera.
  • Eye Sensor - In this mode, both the LCD and viewfinder are active. When you're holding the camera at arm's length, the LCD is active. When you lift the camera to your eye, it automatically shuts off the LCD and activates the viewfinder. You again can switch between electronic and optical viewfinder mode using the toggle switch on the front of the X100F.
I do like the Hybrid Viewfinder because of the flexibility it offers. When shooting different scenes in different lighting conditions, having options as to how to frame the scene is great.

You will notice that you'll end up pressing your nose against the LCD screen when using the viewfinder, which will leave smudges.

back buttons.jpg
You'll find a few different control buttons on the back of the camera along the right side. (In this photo on the top left, you can see half of the AE-L/AF-L button mentioned earlier.)

At the top is the back command dial (in silver). This allows you to zoom into the scene when shooting with manual focus or to magnify an image stored on the memory card. You also can use this dial to make changes to the Q menu.

On the far right near the top of the panel is the Q button, which opens the Q (Quick) menu.

To the left of the Q button is the focus stick, which is a joystick-like button, which makes it easy to select the autofocus point.

Going downward from the focus stick, you'll see the Playback button, which allows you to see the images stored on the memory card; the Delete button, which allows you to delete stored images; and the Disp/Back button, which changes the data displayed on the screen in shooting mode or Playback mode. (You'll also use Disp/Back to back out of a menu.)

The four-way button is in the lower right of the back of the camera. Each button is associated with a specific function. But you can change the left, right, and bottom four-way buttons' functions by using the Setup menu. You cannot change the top button's function. The default functions are:

  • Top button - Drive (Still Image, Continuous Shot, AE Bracket, ISO Bracket, Film Simulation Bracket, White Balance Bracket, Dynamic Range Bracket, Panorama/Multiple Exposure, Advanced Filter, Movie)
  • Right button - White Balance (Auto, Custom 1, Custom 2, Custom 3, Color Temperature, Daylight, Shade, Fluorescent Light-1, Fluorescent Light-2, Fluorescent Light-3, Incandescent, Underwater)
  • Bottom button - AF Mode (Single Point, Zone, Wide/Tracking)
  • Left button - Film Simulation (Standard, Vivid, Soft, Classic Chrome, Pro Neg Hi, Pro Neg Standard, Acros (Standard, Yellow filter, Red filter, Green filter), Monochrome (Standard, Yellow filter, Red filter, Green filter), Sepia)
In the middle of the four-way buttons is the Menu/OK button. You'll use it to open the Fuji X100F's menu screens or make a selection in the menus.

Ports view.jpg

You'll find the X100F's ports stored behind a hard plastic compartment door that snaps into place on the right-hand side of the camera (as you're holding it). From top to bottom, the ports are:

  • Microphone/Remote Release Connector
  • Micro HDMI
  • Micro USB

battery view.jpg
My tests showed the Fujifilm X100F could run for about 225 to 250 shots per battery charge when using the LCD as the primary means of framing photos. If you use the viewfinder primarily, Fujifilm estimates you could receive as many as 390 photos per battery charge, which is a strong performance level.

The battery and memory card slots are both in a compartment in the bottom of the camera. The compartment door is held in place with a toggle switch. Fujifilm included a separate battery charger with the X100F, which is great for those who want to purchase a second battery.
