Some lenses feel like overkill to carry — this one feels like freedom. The OM System M.Zuiko ED 300 mm f/4.0 IS PRO delivers professional telephoto performance in a form that’s light, stabilised, and built to take on anything. Reviewers consistently rank it among the sharpest lenses ever made for the Micro Four Thirds system, praising its optical precision and unmatched image stabilisation.
With a 300 mm focal length (≈ 600 mm full-frame equivalent) and a bright f/4.0 aperture, it captures distant action or wildlife with stunning clarity and subject isolation. Inside, 17 elements in 10 groups — including three Super ED lenses — eliminate chromatic aberration and fringing, ensuring crisp detail edge to edge even wide open.
The lens integrates Sync IS, combining its internal stabilisation with the in-body system of compatible OM cameras for up to 6 stops of compensation. That means you can shoot handheld at long focal lengths, capturing tack-sharp results without lugging a monopod or tripod.
Autofocus is lightning fast and whisper-quiet thanks to its MSC (Movie & Still Compatible) motor, designed for smooth tracking whether shooting bursts of birds in flight or panning in video. Manual focus override and a focus limiter switch provide precise control for demanding compositions, while a sliding focus clutch lets you switch between AF and MF in one smooth motion.
Built to endure, the 300 mm f/4 PRO features a fully weather-sealed magnesium-alloy body, protecting against dust, splashes, and freezing conditions down to –10 °C. The integrated tripod foot keeps the lens balanced on support systems, and its compact design (≈ 1.27 kg) makes it one of the lightest 600 mm equivalents on the market.
The nine-blade circular diaphragm produces beautifully smooth bokeh for portraits or wildlife isolation, while close-focus performance down to 1.4 m adds surprising versatility for small subjects or detail work. Combined with teleconverters, this lens reaches an effective 840 mm or 1200 mm equivalent, maintaining sharpness throughout.
Whether you’re tracking eagles, capturing motorsport, or isolating mountain peaks, the OM System 300 mm f/4 IS PRO gives you handheld reach that used to require a tripod and a hernia belt — all in a lens that fits in your daypack.
