Fujifilm X-T10 Performance

Generally very good performance from the Fuji X-T10.

Power on to first shot was slightly faster than average for a mirrorless camera, but not as fast as most DSLRs. It's also difficult to accurately time, as there is a shutter pre-press penalty. Play to Record wasn't bad, but required two shutter button presses to capture an image.

The Fuji X-T10's full autofocus shutter lag was much faster than average for a mirrorless camera in our lab tests. The Fuji X-T10 produced full-autofocus shutter lag (with the subject at a fixed distance) of only 0.144 second using Single Point AF mode (center) with the 18-55mm kit lens. That's faster than some pro DSLRs. With the built-in flash enabled, the X-T10's full AF shutter lag increased to 0.275 second to account for preflash metering, but that's still fast.

Manual focus shutter lag was quite fast, at 0.090 second, and prefocused shutter lag was quick, at only 0.052 second.

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.

Single-shot cycle times were difficult to measure accurately as it required an irregular rhythm imposed by an intermittent pre-press penalty (if you press the shutter button too soon after a previous shot, the camera may ignore it and you would then need to press again). Best case, we measured about 0.7 second for large/fine JPEGs or RAW+L/F JPEGs, but your experience may vary. (Note that we no longer test single-shot mode with just RAW files, as the result is usually somewhere in between JPEG and RAW+JPEG modes.)

The Fuji X-T10's Continuous High burst mode speed was quite good, at just over 8 frames per second when shooting JPEGs, and 8.1 frames per second for RAW or RAW+JPEG files, slightly exceeding Fuji's 8.0 fps spec. There is also a Continuous Low mode rated at 3.0 fps, but we did not test that in the lab.

Full resolution buffer depths were mediocre, though, at only 10 JPEG frames with our difficult to compress target. You may do better with typical subjects. When shooting RAW or RAW+JPEG files, the buffer depth dropped to only 7 frames. Buffer clearing was a fairly quick 5 seconds after shooting a max-length burst of JPEGs or RAW files, and 7 seconds after a RAW+JPEG burst, though as mentioned, buffer depths weren't very deep.

Recycling the flash after full power discharges took an average of 2.7 seconds, which is good.

Bottom line, the Fuji X-T10's performance was generally very good with a decent startup time, fast autofocus, low shutter lag and a fast 8 fps burst mode. However buffer depths were on the shallow side, and an intermittent shutter pre-press penalty can be a bit annoying at times.

Battery Life
Average battery life for a mirrorless camera.

The Fuji X-T10 uses a custom rechargeable lithium-ion battery pack for power, and comes with both a single battery and a dedicated charger. The CIPA-rated 350 shots per charge when using the LCD monitor is about average for a mirrorless camera, but unfortunately Fujifilm doesn't seem to state what the rating is when using the EVF, however it's often lower. As is usually the case, we strongly recommend getting a second battery for your X-T10 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.
