What You Notice in Use

Stabilization in the body helps when you use lenses without their own, and it steadies handheld video. The newer focus system recognizes more subject types, which may help with animals, vehicles and people at a distance. The articulating screen makes it easier to shoot at awkward angles and to frame yourself without a screen blocked by a mounted microphone.

The A6400 still performs well in daylight with typical subjects. Many users will see little change in a landscape or portrait setting.

How to Choose

  1. Write down the shots you miss now. If focus or blur is the reason, the A6700 may help.
  2. Check if your lenses have stabilization already.
  3. Compare the cost of a used A6400 with what you could spend on a lens.
  4. Handle both for grip comfort.

Who Should Choose Which

  • Choose the A6700 if you shoot video, fast action or use unstabilized primes.
  • Choose the A6400 for travel and general use where a lighter outlay is useful.
  • Keep your lenses either way, since both accept the same E-mount lenses.

Video and Everyday Use

For video, stabilization in the body, a screen that articulates and better subject recognition all make handheld clips easier to keep sharp and framed. For stills, the gains show most with moving subjects and low light. Battery life, card type and port layout also differ between models, so read the maker’s documents if you rely on external microphones or long recording sessions.
