The Fujifilm is a super telephoto lens with an immense focal length and yet compact dimensions and low weight. The performance in terms of sharpness and contrast is very good.
The switches on the lens could offer slightly more options for a more convenient configuration.
This is what sports and wildlife photographers with X cameras have been waiting for: Fujifilm provides a super telephoto lens that utilises the size and weight advantages of a shooting system with an APS-C sensor very nicely. The autofocus supports the AI technology of current X cameras very well.
