When shooting RAW or RAW+JPEG files, buffer depth dropped to a paltry six frames, the same as its predecessor. The buffer-full frame rate was also pretty good, at about 4.5 fps. Note that the electronic shutter is used in 4K Burst mode, so there can be some distortion and/or banding depending on subject/camera motion or artificial lighting.īuffer depth was a decent 22 frames for best quality JPEGs which is much better than Fujifilm's ten frame spec, and much improved over the 9 frames we got with the X-A3. We did however test the X-A5's new 4K Burst mode which worked as expected, capturing 8-megpaixel JPEGs at very close to the camera's 15 fps 4K video frame rate. The Fuji X-A5 also offers a "Continuous L" mode rated at 3 fps, but we didn't test that mode in the lab. ![]() The frame rate dropped just slightly to about 5.7 fps for RAW or RAW+JPEG files. The highest speed full-resolution "Continuous H" burst rate was decent for an entry-level model, clocking in at about 5.8 frames per second for best quality JPEGs, which is pretty close to Fujifilm's 6 fps spec. Single-shot cycle times were also slower than average at well over one second, and the X-A5 has a pre-press penalty (if you press the shutter button too soon after a previous shot, the camera ignores it and you need to press it again). ISO sensitivity and noise reduction settings can also affect cycle times and burst mode performance. Slow cards may also limit length of bursts in continuous mode. ![]() Slower cards will produce correspondingly slower clearing times. *Note: Buffer clearing times measured with a 64GB Lexar Pro 2000x UHS-II SDXC card. 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. As you can see it actually increased lag times. We retested the X-A5's lag times using electronic shutter mode to see how using it impacts performance. ![]() CANT RETRIEVE FUJIFILM SHUTTER COUNT MANUALManual focus shutter lag was a bit faster than the X-A3, at 0.154 vs 0.194 second, and Prefocused shutter lag was quite quick, at only 0.043 versus 0.048 second. CANT RETRIEVE FUJIFILM SHUTTER COUNT FULLWith the built-in flash enabled, the X-A5's full AF shutter lag increased to 0.463 second to account for preflash metering, slightly slower than the X-A3's 0.434 second. We tried multiple lenses including some fast primes, but they produced similar results in this test. CANT RETRIEVE FUJIFILM SHUTTER COUNT UPGRADEThis is marginally improved over X-A3's 0.374 second, but we were hoping the upgrade from a contrast-detect to hybrid AF system would yield significantly faster results. The Fuji X-A5's full-autofocus shutter lag (with the subject at a fixed distance) was 0.328 second using Single Point AF mode (center) with the kit lens (without Pre-AF enabled). The Fuji X-A5's full autofocus shutter lag was slower than average for a mirrorless camera, though there is a "Pre-AF" option which should help by continuously focusing even when the shutter button is not pressed half way (that does however reduce battery life). Time to capture, after half-pressing and holding shutter button. ![]()
