Fujifilm X100VIvsSony a6700: Which to Buy?

The Fujifilm X100VI resolves 40.2 MP against the Sony a6700's 26 MP. That extra pixel density pays off in two ways: cropping a still after the fact, and printing large without upscaling. For everyday sharing and normal-size prints, the gap rarely shows.

What the Sony counters with is reach in low light. Its native ISO ceiling of 32,000 is a stop and a third above the Fujifilm's 12,800, so shooting handheld indoors or at dusk, the Sony gives you more headroom before noise takes over. Fujifilm buyers who nail exposure at base ISO get the resolution; Sony buyers get latitude when the light is bad.

This is the decision. The X100VI's lens is fixed — you buy the camera and the focal length together, and that's the end of it. The a6700 takes Sony E-mount lenses, so you can swap to a wide zoom, a fast prime, or a long telephoto as your interests change.

On autofocus subject detection, the two lists nearly overlap: human, animal, bird, car, train and airplane on both. The X100VI adds motorcycle; the Sony adds insect. Neither addition is a dealmaker. The real AF story here is the mount — subject detection matters far less than whether you can point the right lens at your subject in the first place.

The X100VI shoots 6K, which is the higher resolution number on paper and gives you room to crop or stabilize in post. The a6700 tops out at 4K, but it shoots that 4K at up to 120 fps — twice the Fujifilm's 59.94 fps ceiling. That's the difference between usable slow motion and none.

One caveat on the Sony: full-width 4K only reaches 60 fps. The 120p mode uses a crop, so wide shots lose field of view. Still, if you plan to shoot action or want slow-motion footage without a second camera, the Sony is the one that can do it. Neither camera records raw video, and both give you 10-bit and log profiles.

The X100VI's electronic viewfinder is sharper at 3.69 M dots versus the Sony's 2.36 M dots, and its rear screen is higher resolution too. If you compose through the finder most of the time, the Fujifilm is the more pleasant camera to look through.

The Sony wins on flexibility: its screen is fully articulated, so it flips out to the side and faces forward, which matters for vlogging or shooting at odd angles. The X100VI's screen only tilts. The Sony also has a slightly higher viewfinder magnification, though the difference is small next to the articulation gap.

Battery life is lopsided: the Sony a6700 manages 570 shots per charge against the X100VI's 320. That's roughly 78 percent more shooting per battery, which translates to a genuine difference on a day out — the Fujifilm will likely need a spare in your bag.

The Sony is also smaller and lighter in every dimension except depth: it's 28 g lighter, and shorter in both width and height. The Fujifilm is the slimmer body front-to-back, which is what makes it pocket-friendly with the fixed lens. Add an E-mount zoom to the Sony, though, and its size advantage disappears.

The Sony a6700. Its electronic burst matches the Fujifilm's mechanical 11 fps, and it hits 120 fps in 4K, which is what you need for slow-motion replay of fast movement. Its higher native ISO ceiling also helps indoors and under stadium lights.

The X100VI does edge ahead on electronic burst at 13 fps, and its fixed lens keeps the whole package compact if you're shooting casually. But for serious action work the Sony's lens flexibility and slow-motion video are the deciding factors. Neither camera publishes a pre-burst duration that helps here.
