I use this professionally and it is a dream of a mirror lens. You won't be disappointed.

The lens works perfectly. It is a manual lens so people should be aware that you have to have a good eye to use this. The lens can make a half mile object look close up. For the beginner I would recommend a solid tripod with a remote camera trigger. Oh and the lens came very quickly. Eight days from the USA.
