The Panasonic Leica DG Vario-Elmarit 50-200mm F2.8-4 is a powerful - and portable - telezoom for Micro Four Thirds cameras, providing the equivalent of a 100-400mm focal length range. On paper, this compact stabilized zoom is perfect for wildlife photography, in environments where large, heavy lenses and tripods aren't always practical.

We recently returned from a trip to Yellowstone National Park with the 50-200mm and the Panasonic Lumix DC-G9. Check out our gallery to see how we got on.
