Is the panasonic lumix s1 good for wildlife?
The Lumix S1 can do wildlife, but the body isn't the hard part. Wildlife is about reach, and the S1 is a big, rugged full-frame body with a superb viewfinder, so it's a solid base for long lenses. Its 24.2-megapixel sensor gives you room to crop, which helps when the animal is far away.
For reach, I'd start with these from the catalogue:
- Sigma 150-600mm f/5-6.3 DG DN OS Sports for a lot of reach on a budget.
- Sigma 60-600mm f/4.5-6.3 DG DN OS Sports if you want one lens that covers wide to very long.
- Panasonic Lumix S 100-500mm f/5-7.1 OIS if you want to stay with Panasonic's own glass.
Read wildlife and sport for the reasoning, and buying used if you want to try a long lens without much risk.
