Photozone (Click here) published the full Olympus 60mm macro review: “The question of the day is whether to prefer the Olympus M.Zuiko 60mm f/2.8 ED macro over the Leica DG Macro-Elmarit 45mm f/2.8 ASPH OIS ? As far as the key aspects is concerned the Leica lens may be a tad sharper whereas the M.Zuiko has a slight edge on the bokeh side. The choice is yours. :-)”
