Sony Fe 400-800mm F6.3-8 G Oss

The Sony FE 400-800mm F6.3-8is as big and long a zoom lens as you'll find for any full-frame camera, and enters the E-mount system as the longest focal length entry yet. Its extremely narrow angle of view brings distant subjects into view, an ideal choice for wildlife photography in general, and small, skittish critters like birds especially. We like its mix of internal zoom, fast focus, effective stabilization, and exceptional telephoto reach, but realize it's a hefty lens to carry through the wilderness
