A well designed and compact super wide angle lens. Distorsion control is good but need to be careful depend on photographic situation. Light falls off at large aperture is apparent. This lens has a very pleasant signature. The lens is very compact for this angle coverage. To use a 86mm filter you will need a special 70/86 adaptor, and the filter has to be the thin type.
