The part is with me always with you and makes absolutely hot photos. Professionals are welcome to spend twice as much. Mir long it as a hobby photographer wholeheartedly. It's really amazing how much can be imaged to a photo and how sharp and detailed, these are (see photos).
For me, it was and is the right step was Canon switch to Olympus. The Zuiko lenses and the E-3 have fully convinced me.
This lens gets from me a strong buy recommendation
