Conclusion: The closest focus distance is 110cm, which enables a maximum magnification factor of 0.22x at the 200mm zoom setting. Focusing is internal, so the front element neither extends nor rotates, making it ideal for use with a circular polariser or other rotation-sensitive filter. The lens has a relatively small 55mm filter thread and comes complete with lens hood.
