Is the sony a6600 good for beginners?
Yes, I think the Sony a6600 is a good fit for a beginner who wants to grow into a serious camera. It's a mirrorless APS-C body with in-body stabilisation, a big battery and a deep grip, which helps with handling. That matches what I recommend in your first camera: a mirrorless body with an APS-C sensor, where the money goes further in lenses.
For a first lens on it, I'd start with one of these:
- Sony E 18-55mm f/3.5-5.6 OSS for everyday shooting
- Sony E PZ 16-50mm f/3.5-5.6 OSS if you want a power zoom
- Sony E 18-135mm f/3.5-5.6 OSS if you want one lens to cover most things
If you want to save money, buying used is worth a look.
