Micro Four Thirds (MFT/M43)

Review

The Olympus M.Zuiko Digital ED 100-400mm F5.0-6.3 IS is an impressive telephoto zoom lens designed for Micro Four Thirds camera systems. Offering a versatile focal length equivalent to 200-800mm in the full-frame format, this lens is well-suited for wildlife, sports, and landscape photographers who need to get close to their subjects without physically intruding.

One of the standout features of the 100-400mm F5.0-6.3 IS is its impressive image stabilization system. With up to 3.5 stops of compensation, this feature allows photographers to shoot at slower shutter speeds without the worry of motion blur, which is particularly beneficial when using the longer focal lengths. Additionally, the lens is lightweight and compact for its range, making it a great option for on-the-go shooting and travel.

Image quality is commendable, with good sharpness and detail across the zoom range. It's designed with multiple lens elements, including ED (Extra-low Dispersion) glass, which helps in minimizing chromatic aberration and maintaining clarity even at the edges. The lens also has a weather-sealed construction, providing extra durability and allowing it to withstand challenging environmental conditions.

However, there are some drawbacks to consider. The maximum aperture of F5.0-6.3 may limit performance in low-light scenarios, as well as the ability to achieve a shallow depth of field compared to faster lenses. At the longer end of the zoom, images can become soft if the lens is not properly stabilized or if the shutter speed is too low. Additionally, the lens is not the fastest when it comes to autofocus, which could be a disadvantage for capturing fast-moving subjects.
