Sony a6400 vs sony a6600?
The Sony a6400 and the Sony a6600 share the same 24.2-megapixel APS-C sensor and were both announced in 2019. The a6400 is smaller and very quick to focus, but it has no stabilisation in the body. The a6600 has stabilisation built in, plus a bigger battery and a deeper grip. If you shoot handheld in dim light, I'd pick the a6600. If you want the lightest setup, go with the a6400 and use stabilised lenses.
Both take the same lenses. Good choices include:
- Sony E PZ 16-50mm f/3.5-5.6 OSS for everyday use
- Sigma 18-50mm f/2.8 DC DN Contemporary for brighter, sharper everyday shots
- Sony FE 70-200mm f/2.8 GM OSS for portraits and sport
