The 90mm f/3.5 Macro IS PRO is much more than a standard macro lens. It is a specialized tool that provides an 180mm (full-frame equivalent) working distance, allowing for significant subject-to-lens clearance—ideal for skittish insects. When the "Super Macro" mode is engaged, the lens reaches 2x magnification; if paired with the MC-20 teleconverter, it can achieve a mind-bending 4x magnification (8x full-frame equivalent). The lens features a sophisticated optical design with 18 elements in 13 groups, including Super ED and ED elements to eliminate color fringing at extreme close-up distances. Its built-in Optical Image Stabilization works in harmony with OM SYSTEM cameras to provide up to 7 stops of 5-axis Sync IS, which is critical for the extreme precision required at high magnifications. For workflow efficiency, it includes a focus clutch for instant manual focus override and a focus limiter switch with three positions to minimize hunting. It is fully compatible with in-camera Focus Stacking and Focus Bracketing, ensuring every tiny detail of a subject is in tack-sharp focus.
