Olympus M.Zuiko Digital ED 45mm f1.2 PRO brand_Lee Breakthough Photography calls this anThe Olympus M. Zuiko Digital 45mm f1. 2 is a fast portrait lens for Micro Four Thirds cameras. That f1. 2 aperture gives this lens solid low light capability, but perhaps more importantly, it provides a greater range of depth of field options for more creative control. In excellent condition, with clean glass and good function. Includes hood and softcase.
