Four hundred and twenty-five phase-detection points spread across most of the frame is the number that explains the a6400. It means the camera can find and hold an eye near the edge of the picture, not just in the middle, so you can compose off-center and still get a sharp face. We shot bursts of people walking toward us and the hit rate was the best of anything in this group. An 11 fps burst and a screen that tilts up for waist-level work make that kind of shooting easy to keep up with.
The body is the other half of the argument, and it is the half that kept us picking it up. At about a pound with the 16-50mm zoom fitted it drops into a small shoulder bag, and there is a real electronic viewfinder for bright afternoons — the thing we missed most on the screen-only cameras here. Sony's E-mount is the deepest of the mounts in this group, so the a6400 can start as a one-lens camera and end up as a system you keep adding to.
What you give up is in-body stabilization. Steadiness comes from the lens, and the kit zoom has it, so handheld daylight shots are fine; fit an unstabilized prime and you will want to keep shutter speeds up once the light drops, which is exactly the gap the a6700 fills. The kit zoom is the usual compromise too — it collapses small, then turns slow at the long end. Neither is a reason to walk away; both are reasons to know what your second lens is for.
Pros
- Real-time eye autofocus that holds on moving subjects
- Compact, light body with a built-in viewfinder
- Deepest native lens selection of the picks here
- 4K video and 11 fps bursts
Cons
- Battery life falls short of a full day
- Screen tilts but does not swing out sideways
We recommend the a6400 as the default compact APS-C camera: the surest autofocus here, a viewfinder, and a lens mount worth growing into.
