Best lenses for the Olympus OM-D E-M1: Short telephoto and standard focal lengthsBy Kevin Carter - Friday November 29 2013 Lens Recommendations
The previous best performing zoom has been pushed to second place by the new 12-40mm f2.8 Pro from Olympus. This was launched with the E-M1 and while it’s a great performer optically there’s not much between it and the slightly shorter range Panasonic.
In third place is the Panasonic’s sibling, the 35-100mm (70-200mm equivalent). Despite the longer focal lengths this model has slightly higher average peak sharpness, but at $1,300 it’s aimed at professionals and enthusiasts.
