What this lens is good for
Portraits
This is a dedicated portrait lens. The 90mm full-frame equivalent flatters faces and compresses the background, while f/1.2 delivers the shallowest depth of field and smoothest bokeh of any autofocus portrait lens in the OM lineup. Olympus specifically engineered its rendering for feathered, natural-looking out-of-focus areas.
Weddings and events
Weather sealing, fast and accurate autofocus, and the bright f/1.2 aperture make it a workhorse for professional portrait and event shooters who need to work in low light and deliver consistently sharp results with beautiful separation.
