At 400 mm and open aperture 6.3, but also at aperture 13, the resolution in the centre of the image drops to 1200 line pairs. We also measure even lower values for contrast. The edge drop is again low. Thus the decisive 400 mm position remains almost 20 points below the average value of the Olympus lenses, and a recommendation is therefore omitted.

Micro Four Thirds, Micro Four ThirdsProduct details
The new M.Zuiko Digital ED 5.0-6.3/100-400mm IS EZ_M1040 is a powerful yet relatively compact super telephoto zoom lens weighing just 1120 grams. With a focal length range of 100-400mm, it extends into the super telephoto range, equivalent to a full-frame zoom of 200-800mm. It is compatible with both teleconverters, allowing its focal length to be doubled to 800mm or 1600mm in full-frame terms. The ZERO coating (Zuiko Extra-low Reflection Optical) reduces ghosting and flare even in challenging conditions such as backlighting. Dust, splash, and frost protection from the M.Zuiko PRO series: The effective hermetic sealing of the entire lens barrel makes the new model absolutely reliable, even in harsh environments.
