What is the leica vario elmar sl 100 400mm f 5 6 3 good for?

This is Leica's longest SL zoom, and I'd point it at sport from the sideline and larger animals. On full frame it covers 100-400mm. On an APS-C L-Mount body it frames like 150-600mm, which gives you more reach for the money and the weight. It's stabilised, autofocuses, and works with the Extender L 1.4x if you need more.

The catch is the aperture. At f/5-6.3 it gets darker as you zoom in, so it works best in good light. For small birds, you'll want more reach than this lens gives. The wildlife and sport guide explains the focal lengths, and my picks suggest what to pair with it.
