The Fujifilm X-S10 is a mirrorless crop-sensor camera. It delivers great image quality and records reasonably sharp, detailed video in both 4k and FHD, though you may notice some noise when shooting in dimly lit environments. Its in-body image stabilization feature also helps smooth out camera shake in both still photography and video. It's comfortable to use, feels impressively well-built, and has a bright, sharp, fully-articulated screen, along with a wide assortment of ports for using accessories. While its autofocus performance in video is fantastic, it has a hard time maintaining focus on subjects when used for still photography.
The Fujifilm X-S10 is good for travel photography. It delivers impressive image quality out-of-the-box, with minimal amounts of noise even at moderately high ISO levels. The Fujifilm Simulation modes can help give your shots a bit of added flair, though we don't currently test the camera with these modes enabled, and you can only apply them to JPG files. It features a very wide shutter speed range to help you capture both quick moments or take complex long-exposure shots. It's also comfortable to use for the most part and feels impressively well-built. Unfortunately, depending on your usage habits and choice of settings, its single-charge battery life might be insufficient for a long day of shooting.
The Fujifilm X-S10 is a very good option for landscape photography. Image quality is great overall, with excellent noise handling capability even at higher ISO levels, which is good if you plan on shooting in darker environments. The built-in Fujifilm Simulation modes also allow you to give your shots a distinctive look; be aware that you can only apply them to JPG files, and we don't currently test the camera with these modes. Its fully-articulated touchscreen allows you to easily shoot from above your head or below the hip and is bright enough to be easily seen even under direct sunlight. It isn't too difficult to carry around for extended shooting sessions and feels very well-built, though it isn't weather-sealed. However, we don't currently test for that.
The Fujifilm X-S10 is decent for sports and wildlife photography. When using its electronic shutter, it can capture up to 20 shots per second without a crop. This, combined with its fast max shutter speed, should help you capture clear stills of fast-moving subjects, like cars on a track. Image quality is great, too, even at fairly high ISO levels. It feels well-built and is quite comfortable to operate as well. Unfortunately, its autofocus system can have a hard time tracking the movement of some subjects and, depending on your usage habits and choice of settings, battery performance is unimpressive.
The Fujifilm X-S10 is a great option for vlogging. Its fully-articulated touchscreen allows you to monitor your recording even when the camera is pointed at you, and it isn't too fatiguing to carry around. Its ergonomic grip also makes it a little easier to hold while vlogging compared to some other models in Fujifilm's model lineup. Its in-body image stabilization, combined with the FUJINON XF 18-55mm F2.8-4 R OIS kit lens' optical stabilization feature, helps the camera do an impressive job of smoothing out camera shake in both FHD and 4k video. Video quality is also good in either resolution, though you may notice some noise when shooting in dimmer environments. Its autofocus system is remarkably effective in terms of tracking subjects' faces, too.
The Fujifilm X-S10 is great for studio video. Video quality in FHD and 4k is sharp and detailed overall, though you may notice some graininess when recording in dimly-lit environments. It supports F-Log shooting for an expanded dynamic range in video and allowing for in-depth color grading in editing, though we don't currently test this function. While it's only capable of shooting 8-bit 4:2:0 color video internally, it can output 10-bit 4:2:2 color video through its HDMI port, which you can take advantage of by using an external recorder. It features dedicated headphone and microphone jacks too. You can also charge it over USB while in use, which is good for extended recording sessions.
The Fujifilm X-S10 isn't for action video. It's too big to be mounted on a chest or helmet and isn't rated as being water or impact-resistant, though we don't currently test that. It's also incapable of shooting natively at more than 60 fps in FHD and 30 fps in 4k, though it does have dedicated slow-motion recording modes for FHD video. Its in-body image stabilization and kit lens' optical stabilization features also reduce camera shake by an impressive amount.
Note: Using the electronic shutter allows you to fire at up to 30 fps, but doing so incurs a crop on your image. Also, shooting at 20 fps with the electronic shutter lowers the JPEG buffer size to 56 shots and increases the buffer clearing time from '0s' to '7.45s' compared to the results shown, which we achieved with the mechanical shutter.
Note: This camera is capable of shooting at ISO 100, but only as an extended minimum. ISO 51200 is considered an extended ISO maximum. Results from images taken at those ISO levels may not be fully comparable to other cameras that we've tested.
Update 06/23/2021: We've updated the frame rates for this camera. Like the Fujifilm X-T4, the X-S10 is capable of recording high-speed FHD video in 120 fps and 240 fps, but it only allows for playback of this footage in 10x, 8x, 4x, or 2x slow motion speed. It can't actually playback this footage at high speed, and it doesn't record sound in this mode, either. This feature is available in the 'Full HD High Speed Rec' menu (see here and here). Enabling this feature also incurs a crop.
The Fujifilm X-S10 is only available in one color scheme: 'Black', and you can see its label here. We tested it in conjunction with the FUJINON XF 18-55mm F2.8-4 R OIS lens, though you can also buy it without a lens at all.
Let us know in the discussions if you come across another variant of this camera, and we'll update our review.
The Sony ZV-1 and the Fujifilm X-S10 are both well-suited to vlogging, but they're also different camera types. The Fujifilm is an interchangeable lens camera with an APS-C sensor, so it's more versatile and delivers better overall image and video quality. It also has better internal video recording capability, meaning it can output higher quality video files for more advanced video work. That said, the Sony camera's compact form factor and convenience make it a good alternative if you just want something portable for walk-and-talk vlogging.
The Sony α6600 and the Fujifilm X-S10 are both APS-C mirrorless cameras that perform similarly overall. Both cameras have IBIS and deliver excellent out-of-camera JPEGs, although the Fujifilm offers several film simulation profiles to help you play with the look of your photos in-camera. The Fujifilm camera has better RAW noise handling performance at higher ISO settings for low-light situations. That said, the Sony camera has a more consistent and reliable autofocus system, a larger EVF, and a significantly longer battery life. It's also weather-sealed against moisture and dust.
