Very happy with this purchase, the objective now left almost my camera. The pros: metal drum that exudes strength focus ring precise manual focus open from 2.8 to 40mm allows for beautiful bokeh focusing distance relatively short minimum focusing silent
The -: lens hood and cap before finits evil (some parts were detached during a very mild shock. The good news is that the elements are of very good quality and very good design, which allows very neatly repaired with a small dot of glue)
