Fuji X100F Performance

Timing and Performance

Very good overall performance in the lab.

Startup/Play to Record

Power on
to first shot

~1.4 seconds

Time it takes to turn on and capture a shot.

Play to Record,
first shot

~1.0 second

Time until first shot is captured.

Power on to first shot was slightly faster than average for a compact camera. Play to Record wasn't bad. Note that Play to Record requires two presses of the shutter button.

Shutter Response (Lag Time)

Full Autofocus,
Single Point (center) AF mode

0.246 second

Time from fully pressing shutter button to image capture, with the lens already at the proper focal distance setting.

Full Autofocus
Single-area AF mode
Flash enabled

0.373 second

Time from fully pressing shutter button to image capture. Auto Flash enabled.

Manual Focus

0.034 second

For most cameras, shutter lag is less in manual focus than autofocus, but usually not as fast as when the camera is "prefocused".


0.014 second

Time to capture, after half-pressing and holding shutter button.

The Fuji X100F's full autofocus shutter lag was quite good for a compact camera in our lab tests. The Fuji X100F produced a full-autofocus shutter lag (with the subject at a fixed distance) of 0.246 second using Single Point AF mode (center). Enabling the built-in flash in Auto mode increased full AF shutter lag to 0.373 second due to pre-flash metering, but that's still good.

Manual focus shutter lag was very fast, with an average of only 0.034 second. Prefocused shutter lag was very low at only 0.014 second. Excellent performance.

Note that Standard Power Management mode was used for our timing tests which sets AF performance to High (the fastest mode) and LCD/EVF display quality to High (instead of Very High in High Performance mode).

To minimize the effect of different lens' focusing speed, we test AF-active shutter lag with the lens already set to the correct focal distance.

Cycle Time (shot to shot)

Single Shot mode
Large/Fine JPEG

< 0.3 second

Time per shot, averaged over a few frames (we no longer test for buffer depths in single-shot mode).

Single Shot mode

< 0.3 second

Time per shot, averaged over a few frames (we no longer test for buffer depths in single-shot mode).

Early shutter


Some cameras don't snap another shot if you release and press the shutter too quickly in Single Shot mode, making "No" the preferred answer.

Continuous 8.0 fps
Large Fine JPEG

0.13 second
(7.99 fps);
49 frames total;
6 seconds to clear*

Time per shot, averaged over buffer length of 49 frames. Then slows to an average of 0.20s or 4.95 fps when buffer is full.

Continuous 8.0 fps
Losslessly Compressed RAW

0.13 second
(7.97 fps);
30 frames total;
9 seconds to clear*

Time per shot, averaged over buffer length of 30 frames. Then slows to an average of 0.38s or 2.64 fps when buffer is full.

Continuous 8.0 fps
Lossless RAW + L/F JPEG

0.13 second
(8.00 fps);
25 frames total;
14 seconds to clear*

Time per shot, averaged over buffer length of 25 frames. Then slows to an average of 0.54s or 1.86 fps when buffer is full with a lot of variation.

Flash Recycling

4.6 seconds

Flash at maximum output.

*Note: Buffer clearing times tested with a SanDisk Extreme Pro 95 MB/sec UHS-I SDHC card. Slower cards will produce correspondingly slower clearing times. Slow cards may also limit length of bursts in continuous mode. ISO sensitivity and noise reduction settings can also affect cycle times and burst mode performance.

Single-shot cycle times were so fast that they were difficult to accurately measure as they depend on the tester's dexterity and ability to maintain an optimum rhythm. (Note that we no longer test single-shot mode with just RAW files, as the results are usually somewhere in between JPEG and RAW+JPEG.)

The Fuji X100F's fastest 8.0 fps Continuous mode speed was good, testing at very close to 8 frames per second no matter the file type, meeting Fuji's spec. The X100F also offers 5.0, 4.0 and 3.0 fps modes, however we didn't test those.

Full-resolution buffer depths were quite good in 8.0 fps burst mode with our fast SanDisk Extreme Pro UHS-I SDHC card with buffer depths of 49 best quality JPEGs, 30 losslessly compressed RAW files, and 25 RAW+JPEG files before the camera slowed in our tests. Fuji specified 60 JPEGs and 25 losslessly compressed RAW frames so it fell a bit short of spec for JPEGs but exceeded the spec for RAW files. The camera also offers uncompressed RAW files which Fuji claims will yield a buffer depth of about 2 frames less than losslessly compressed at 8.0 fps.

Buffer clearing was reasonably quick considering the resolution, taking between 6 and 14 seconds to clear after a max-length burst depending on the file type, and the camera lets you adjust settings as well as view just-shot images while the buffer is clearing.

Recycling the built-in flash after full-power discharges took an average of 4.6 seconds, which is fair.

Bottom line, the Fuji X100F's performance is very good with a decent startup time, fast autofocus, very low shutter lag, very fast cycle times, and a fairly quick burst mode with decent buffer depths and reasonable buffer clearing when using a fast UHS-I card.

The Fuji X100F uses a custom NP-W126S rechargeable lithium-ion battery pack for power, and comes with both a single battery and a dedicated charger, although in-camera charging via USB is also supported. Fuji provides battery life numbers when using the LCD, EVF or OVF and for 3 different power management modes. CIPA-rated battery life is fair for a premium large-sensored compact and quite good when using the optical viewfinder. As is usually the case, though, we still recommend getting a second battery for your X100F if you plan any extended outings.

The table above shows the number of shots the camera is capable of (on a fully-charged rechargeable battery), based on CIPA battery-life and/or manufacturer standard test conditions.
