What reviewers found
Synthesized across the trust-weighted source mix below.
For people stepping up from a phone into a serious interchangeable-lens system, the Sony a6400 is the camera the reviewers we read mention most often. The dpreview review calls it 'near-universally capable' with a market-leading autofocus implementation at a modest price, and r/Cameras threads — including high-trust community discussion — describe it as remarkable bang for the buck and competitive with current mirrorless bodies in its price bracket. With nearly 1,000 verified Amazon reviews averaging 4.5 stars, the customer signal is unusually deep for this category.
What reviewers liked
- Nearly 1,000 verified Amazon reviews averaging 4.5 — by far the deepest consumer signal here
- dpreview and r/Cameras community converge on 'excellent value' verdict
- Real-time Eye AF is repeatedly singled out as class-leading at the price
- Compact APS-C body is genuinely portable for travel and walk-around use
Where it falls short
- High-trust r/Cameras discussion flags noticeable rolling shutter in 4K
- Video feature set is dated compared to newer APS-C bodies, per r/SonyAlpha
- Bundled 16-50mm kit lens is widely considered the weak link
- Specialist communities note Sony APS-C native lens selection still lags Fuji and Canon

The honest disagreements are around video. A high-trust r/Cameras thread flags 'gnarly' rolling shutter under fast motion, and r/SonyAlpha posters note the video feature set is dated next to the newer a6700. Photo-first beginners get a very capable starter; video-first creators may want to look at the newer Sony APS-C or Canon R50 instead. Reviewers also broadly agree the bundled 16-50mm kit lens is the weakest part of the package and most buyers will want a prime or better zoom early on.

It's usable but definitely not as good as some other brands. 4K looks pretty good but can have very gnarly rolling shutter. That said, overall, ...
It's quite good, and remarkable bang for the buck. Most modern mirrorless cameras in the same price bracket will be roughly competitive with it.
