Just took an ED 75mm f1.8 to Shikoku, teamed with an Olympus OMD, for the completion of an OHenro pilgrimage and am very pleased with the quality of the images. As with most fast lenses there is some CA noticeable on highlights at f1.8 but stopped down this is controllable. The colour and bokeh are superb and the built quality lends a definite confidence to use. Care should be taken in the wet, however, as the unit is not weather sealed. The lens has just the right heft on the OMD so the combination feels comfortable for prolonged shooting. Cudos to Olympus for creating such an excellent tool to accompany the OMD.
