Best budget lens for the nikon d6?
For a budget lens on the Nikon D6, I'd start with the Nikon AF-S 50mm f/1.8G. It's the kind of cheap, fast prime my first camera guide recommends for people and low light.
If you want something wider for everyday shooting, try the Nikon AF-S 35mm f/1.8G ED. For portraits, the Nikon AF-S 85mm f/1.8G is a good choice.
The D6 has no in-body stabilisation, so these primes work best in decent light or with a fast shutter speed. For more on lens choice, see lenses.
