Is the nikon d750 good for wildlife?
Yes, the D750 is a solid body for wildlife, with one catch. It has no stabilisation in the body, so pick lenses that have it built in. Its 24.3 megapixels are plenty for most wildlife, and full frame helps when the light drops at dawn and dusk. The reach comes from the lens, so these are the ones I'd look at first:
- Nikon AF-S 200-500mm f/5.6E ED VR: a versatile zoom with VR
- Nikon AF-S 300mm f/4E PF ED VR: a prime with VR for steadier shooting
- Sigma 120-300mm f/2.8 DG OS HSM Sports: a bright option for poor light
Wildlife is the hardest thing to shoot, so read wildlife and sport first. If you want to try a long lens without much risk, buying used explains why lenses are the easiest way in.
