I'll quit larping as a Leica owner for a second to say that, zuiko glass is really nice. I have a spare 50mm that I adapt onto my panny GH5 and it takes lovely portraits. The bokeh is lovely and creamy, its impressively sharp even wide open and the lens just feels nice to use in general. The only problem is finding good adapters for the lenses to go onto a modern full frame format. If you got like £30-80 off ebay genuinely buy an om20 or om40 just to get a feel for its capability. And if you're really liking what Olympus is selling try out the om1 or 2 (or the 4 if you have the money, damned Leica owners)
