OM System M.Zuiko 8-25mm f/4 PRO 25mm
A constant f/4 aperture across an ultra-wide 16-50mm full-frame equivalent zoom range and a fully weather-sealed build make this lens a reliable field companion. The manual focus clutch and silent MSC autofocus enable fluid transitions between stills and video, while the 411g weight keeps the kit portable. It’s best for landscape and travel photographers seeking an all-in-one wide-angle zoom that can withstand inclement conditions.
