Is the sony a1 good for wildlife?
The Sony a1 is a capable body for wildlife, and its 50.1-megapixel sensor gives you room to crop. Wildlife is also one of the most gear-dependent kinds of photography, so the lens matters most. The wildlife and sport guide covers why.
For reach, I'd start with these from the a1's lens list:
- Sigma 300-600mm f/4 DG OS Sports if you want the fastest aperture at long reach.
- Sony FE 200-600mm f/5.6-6.3 G OSS for a Sony-made option that covers 200 to 600mm.
- Sigma 150-600mm f/5-6.3 DG DN OS Sports if you want more reach for less money.
If you're not sure you'll stick with wildlife, buying used is a good way to try a long lens without much risk.
