OM System's updated 50mm equivalent prime for MFT — sharp, compact, and great for portraits on a budget.
The OM System M.Zuiko Digital ED 25mm f/1.8 II is a refresh of the popular Olympus 25mm f/1.8, now under the OM System brand. It provides a 50mm equivalent standard perspective with a fast f/1.8 aperture on Micro Four Thirds, ideal for portraits and everyday shooting.
Optically good — sharp from f/2.5 with pleasant bokeh at f/1.8. The fast aperture provides decent subject separation despite the MFT sensor's greater depth of field. MSC autofocus motor is fast and quiet. Good for both stills and video.
Micro Four Thirds mount with 46mm filter thread. Weighs approximately 137g — very compact. No weather sealing. Minimum focus distance 25cm. 7 rounded aperture blades. Metal mount with plastic barrel. The Mark II adds minor cosmetic and coating updates over the original.
Available used at budget prices. The original Olympus 25mm f/1.8 is functionally identical and often cheaper. The Panasonic 25mm f/1.7 is a strong competitor. An excellent everyday prime for MFT shooters — the nifty-fifty equivalent of the Micro Four Thirds world.
