Who always wanted to know what you can do with a 3000 mm focal length lens, here there is the opportunity to learn this. I've photographed from a 600 m bottomed a summit cross on a nearly 3000. I never expected to be able to see the guy ropes on the summit cross in the photo. But it was so! This lens has excited me. Everything else is largely standard and contemporary perfectly. Actual is the tremendous variety of settings. It takes until it found its path. But then you have a perfect device to a large extent. Since little to be desired.
