Sony a6700 vs sony fx30?
For most people I'd pick the a6700. It has in-body stabilisation, subject-detection autofocus and a proper grip, and it's Sony's best APS-C body. See the Sony a6700.
The FX30 is a video body with no viewfinder, but it has a fan for long recording. If you shoot a lot of long video, that fan is the reason to buy it. If you mostly shoot stills, skip it. See the Sony FX30.
Both take the same lenses, so choose by what you shoot:
- Sony E 18-135mm f/3.5-5.6 OSS for a wide everyday range
- Sigma 18-50mm f/2.8 DC DN Contemporary for a brighter standard zoom
- Sony FE 70-200mm f/2.8 GM OSS for sport and portraits
