In addition to the 12-40 / 2.8 thought surprised me the 40-150. It is much smaller, very light and fits in perfectly with E-M1. The autofocus is very fast and virtually inaudible. Sure, that part is completely made of plastic, and the bayonet. However, it is tight, without any play or rattling on Body.
Very good harmonizes the comparatively long focal length with the stabilizer of E-M1, also times to 1/8 can grow well and quietly.
Given the price that's probably one of the best digital zoom lenses for OMD's that you can buy at the time.
