Option 2: Nikon 500mm f/4E FL ED AF-S VR
- Lighter weight than the previous version
- Excellent optics
- Advanced VR
- Faster focusing
- Still very heavy
- Very expensive
It's undoubtedly the most expensive lens you'll ever buy, but for a dedicated wildlife photographer, you can't beat Nikon's 2015 update to the 600mm f/4. It's lighter weight, faster focusing, and even better optically than the previous version. If you have the money, then definitely pick the 600.
