OM System OM-1 Mark II
The OM System OM-1 Mark II is the strongest argument for the Micro Four Thirds format in 2026, leaning into the system's strengths rather than apologizing for its smaller sensor.
Read the product overview
Its standout features are class-leading weather sealing, up to 8.5 stops of in-body stabilization, and computational modes like Live ND and high-resolution capture that solve real problems in the field. Paired with compact, lightweight telephoto lenses, it is a remarkable wildlife and travel kit that weighs a fraction of a full-frame equivalent. The trade-off is the smaller sensor's limits in very low light and shallow depth of field, so it rewards photographers who value reach, ruggedness, and portability over the absolute best high-ISO files.

How we assess prices
We use in-stock offers checked within 72 hours. Scores compare the current offer with that retailer’s observations from the last 90 days, requiring at least 14 observed days and a price from about 30 days ago. Suspect records withhold the score. Retailer conditions and prices can change.
