Description — Olympus 12-45mm f/4 PRO
The Olympus M.Zuiko Digital ED 12-45mm f/4 PRO is a Micro Four Thirds mount zoom lens covering a focal length range of 12mm to 45mm. It maintains a constant f/4 maximum aperture throughout the entire zoom range, providing predictable and consistent exposure whether shooting at the wide end or zoomed in. Weighing just 254g, this lens is impressively compact for an autofocus standard zoom with a constant aperture, making it well-suited for travel, street, and everyday photography where pack weight matters.
The 58mm filter thread accepts a wide variety of readily available filter accessories. The lens supports both autofocus and manual focus, giving photographers full control over their focusing method. It is designed exclusively for the Micro Four Thirds mirrorless camera system.
One important consideration: the specifications confirm no optical image stabilization is built into this lens, so users should factor in whether their camera body provides in-body stabilization if that feature is a priority.
