Best telephoto lens for the nikon d5300?

For the D5300, I'd choose by reach versus light. It's an APS-C body, so a 300mm lens frames like 450mm on full frame. The body has no stabilisation, so pick a lens with its own VR or OS.

If you shoot wildlife or sport, the wildlife and sport guide explains how to choose between them.
