What reviewers say

Both reviews praise sharp images, portability and affordable long reach, but find the fixed f/11 aperture restrictive in poor light. Autofocus works well in suitable conditions, within a reduced focus area. Abbott warns that extending and locking the barrel can cost shots. Cameralabs records more modest stabilisation gains than Abbott and prefers the 600mm's handling to the 800mm.
