Head-to-head
Sony a6400 vs a6700: a6700 helps a non-OSS lens and monitored video, a6400 includes a zoom
The short answer
a6700 helps a non-OSS lens and monitored video, while this a6400 offer includes a zoom. Choose a6700 when body stabilization, a side-facing screen with a top microphone, headphone monitoring or 4K120 solves a regular problem. Choose a6400 when its original 16-50mm kit and ordinary 4K30 cover the job. The a6700 offer is body-only. The verified a6400 New offer is third-party, so check the seller, US warranty and original-lens package before ordering.
Before you choose
The reasoning and the trade-offs
The upgrade matters more with the lens that lacks stabilization
If you use the original OSS kit zoom outside and a non-OSS prime indoors, the two lenses create different upgrade arguments. a6400 relies on the lens for optical stabilization. a6700 can add sensor-shift correction with a compatible non-OSS lens when the subject is still. That can help with a room detail or a seated relative, while a running pet still needs a fast enough shutter. If your missed photographs are caused by subject movement, buying a6700 for stabilization alone may leave the problem intact. Keep the lens, lighting and shutter choice in the diagnosis instead of treating IBIS as a general cure for blur.
What this is based on
Explicit a6400 lens-only stabilization and a6700 sensor-shift support. Static versus moving subject distinction. No medical, stop-count or guaranteed sharpness claim.
Main trade-off
Sony a6700 body
Body only and one card slot. 4K120 narrows framing and needs the correct card for the selected mode.
Sony a6400 with original 16-50mm OSS
- Choose it for
- You want the original 16-50mm OSS lens included and can work within 4K30, without headphone monitoring or body stabilization. Check the third-party seller and US warranty.
- Your compatible stabilized lenses already cover mostly still photography, and the lighter 403g body is useful before adding the lens.
- Main trade-off
- No headphone output or body stabilization. A top-mounted microphone may obscure the flip-up screen. The verified seller is Web Offers, with US warranty unverified.
Sony a6700 body
- Choose it for
- A compatible non-OSS prime needs camera-shake correction for still scenes, or an external microphone needs monitoring while recording.
- You need 4K120 and accept its extra crop, exact card requirements and lack of internal 120p proxies. The linked a6700 has no lens.
- Main trade-off
- Body only and one card slot. 4K120 narrows framing and needs the correct card for the selected mode.
About this comparison
Sony a6400 vs a6700 for existing lenses, family interviews and handheld stills. Check when body stabilization or 4K120 is worth the extra setup.
These are an established entry kit and the higher-end current APS-C upgrade within the same E-mount system. A buyer can retain compatible lenses while deciding whether the newer body solves a real stills or video limitation.

What matters in practice
The differences that matter
The upgrade matters more with the lens that lacks stabilization
If you use the original OSS kit zoom outside and a non-OSS prime indoors, the two lenses create different upgrade arguments. a6400 relies on the lens for optical stabilization. a6700 can add sensor-shift correction with a compatible non-OSS lens when the subject is still.

Keep the lens, lighting and shutter choice in the diagnosis instead of treating IBIS as a general cure for blur.
How we reached this conclusion
Explicit a6400 lens-only stabilization and a6700 sensor-shift support. Static versus moving subject distinction. No medical, stop-count or guaranteed sharpness claim.
A top microphone can turn the older screen into an accessory problem
When you film yourself cooking or talking with the children, a microphone in the camera shoe can sit in front of a6400’s upward-facing screen. A suitable offset mount can restore the view, but adds another part to carry and position. a6700’s side-hinged screen avoids that particular top-screen conflict. Its headphone socket also lets someone listen to the microphone feed. Check the exact microphone, bracket and side cables because a crowded rig can obstruct either screen. For someone almost always behind the camera, this is a weaker reason to upgrade than it is for a person regularly filming alone.
How we reached this conclusion
a6400 up 180-degree screen, shoe and absent headphone output versus a6700 vari-angle screen and headphones. Obstruction is conditional on microphone geometry, not universal.
4K slow motion can add work at the computer as well as at the camera
a6700 can preserve a 4K file while recording fast action at up to 120p. a6400’s high-frame-rate option is Full HD. Before choosing the newer body for children’s sport, account for the narrower 4K120 framing and the card required by the exact codec and mode. Sony also disables internal proxy recording at 120p/100p. If your laptop depends on lightweight proxy files, you may need to create them after copying the footage. That is extra work before the family clip is ready to share. a6700 is worthwhile when 4K slow motion is genuinely used, while a6400 may cover ordinary-speed clips without that upgrade.
How we reached this conclusion
a6400 recording inventory and a6700 movie/card guide. 120p proxies unavailable. Additional crop is documented without assigning an unverified numeric factor. Editing consequence assumes a proxy-dependent workflow.

Meaningful differences
What changes the fit
| What changes | Sony a6400 with original 16-50mm OSS | Sony a6700 body | Why it matters |
|---|---|---|---|
| A compatible lens without OSS | No body stabilization | Five-axis sensor-shift stabilization | a6700 can address hand shake in static scenes without replacing that lens. |
| Microphone and self-framing | Mic input, up-flipping screen, no headphones | Mic input, vari-angle screen and headphones | a6700 makes a solo spoken-video setup easier to arrange and check. |
| High-frame-rate recording | 4K up to 29.97p, Full HD up to 119.88p | 4K up to 119.88p with additional crop | Keeping 4K in slow motion changes the lens and card plan. |
| Memory interface | One UHS-I SD-compatible slot | One UHS-II SD slot, format-specific V60/V90 requirements | A card that worked in the older camera may not cover the new mode. |
| Selected package | Original 16-50mm OSS kit, third-party New offer | Body-only ILCE6700/B | Lens inclusion and seller terms belong beside the price. |
What you give up
Every choice has a cost
If you choose Sony a6400 with original 16-50mm OSS
- A lens, microphone mount or recording arrangement may need changing later. Do not assume the older kit is equivalent to a newer OSS II package.
If you choose Sony a6700 body
- Keeping an E lens can lower the upgrade cost, but the intended video mode may still need another card or wider lens.
Recommendation switch
The decision flips if...
Lens-based stabilization and ordinary 4K30 meet the need
Choose Sony a6400 with original 16-50mm OSS. The older kit can be sufficient after seller and package checks.
Body IS, monitored solo video or 4K slow motion solves a real problem
Choose Sony a6700 body. a6700 adds those capabilities while keeping compatible E lenses.
What matters in practice
Before you choose
You want better family photos and clips without buying a new body for a problem that is really the lens, microphone or recording settings.
What this comparison cannot tell you
- No measured autofocus, noise or image-quality winner.
- A body upgrade does not freeze moving subjects through stabilization.
