Olympus M.ZUIKO 75mm f/1.8 ED - Review / Test Report
Lens Reviews - (Micro-)Four-Thirds

Review by Klaus Schroiff, published April 2013

Introduction

The micro-four-thirds (MFT) system may be the most complete of the mirrorless systems. However, it mostly tackles entry to medium level users but slowly but steadily we are seeing more ambitious offerings. The Olympus M.Zuiko 75mm f/1.8 ED is certainly among them. It has a fairly "unusual" focal length equivalent to a 150mm lens on classic full format cameras. As such it is a moderately long tele lens suitable for applications such as portrait and still-life photography. At f/1.8 it is very fast by MFT standards but keep in mind that in terms of depth-of-field is behaves like a "150mm f/3.6" (full format). While this may not be highly impressive it is usually "good enough" for many if not most scenarios in this focal length class.

The build quality of the Zuiko is highly impressive thanks to an all-metal body and a smoothly operating focus ring - to date this is probably the best MFT lens in this respect that found its way into the (photo-)zone. It is far from being a budget item so it is somewhat surprising that the (barrel-shaped) lens hood is just an optional and rather pricey accessory. The lens is also not weather-sealed which is the only downside we can spot here.

The 75mm f/1.8 features a MSC ("Movie and Stills Compatible") AF drive offering a silent, fast and smooth AF. Typical for mirrorless systems the AF accuracy is very high (although this is more a camera rather than a lens aspect).
Just like on the other MFT lenses, manual focusing is "by-wire" so you actually drive the AF motor when turning the broad focus ring. However, the mechanism is particularly well implemented and pretty comparable to conventional mechanisms.
