Fujifilm X-Pro3 vs Sony a6600 — Which Is Better?

The Fujifilm X-Pro3 and Sony a6600 are both APS-C mirrorless cameras released in 2019, so the first decision is which native lens system you build on. The X-Pro3 uses the Fujifilm X mount, while the a6600 uses Sony E, and neither body accepts the other brand's lenses.

Weight is close at 497 g versus 503 g, and the shapes differ more. The X-Pro3 measures 141 x 83 x 46 mm, longer and shallower, while the a6600 at 120 x 67 x 69 mm is taller and deeper.

The Sony a6600 is the stronger choice for handheld work in dim interiors or at dusk, because it offers in-body stabilisation while the X-Pro3 does not. That keeps handheld shutter speeds usable without a tripod. The a6600 also offers 425 autofocus points, against 117 on the X-Pro3.

For bright-light stills the X-Pro3 has the edge, with a 1/32000 second maximum shutter that allows shorter exposures than the a6600's 1/4000 second, useful for wide apertures in sunshine. Resolution is close at 26 MP versus 24.2 MP, so cropping room differs little. Both shoot at up to 11 fps, and both use electronic viewfinders, the X-Pro3's denser at 3690000 dots against 2359296.

The X-Pro3 is the better pick for slow motion, with a 120 fps maximum frame rate against 30 fps on the a6600. Filming street action or sports at 120 fps gives far more room to slow footage in editing. Both cameras record up to 4K resolution.

Both offer built-in timelapse recording, so interval work needs no external trigger. File formats differ, with the X-Pro3 writing MPEG-4 and H.264 while the a6600 adds AVCHD and XAVC S alongside MPEG-4.

The X-Pro3 gives a sharper review experience, with a 1620000-dot rear screen against 921600 dots on the a6600, so playback and menu text render with more detail.

The two also match on shooting features. Both offer a 3-inch touchscreen with live view and a flipping screen for angled shots, both are weather-sealed, and both support Wi-Fi and Bluetooth plus external flash. Neither includes GPS or a built-in flash.

The a6600 holds the battery advantage, rated at 810 shots against 400 on the X-Pro3, roughly double the rating per charge.

For storage, the X-Pro3 offers two card slots against the a6600's single slot, plus UHS-II SD card support. That extra slot suits event and wedding work where carrying a spare card in the body is useful. The a6600 also accepts Memory Stick Pro Duo, and both cameras charge over USB.
