Hi,
If it's any use to any one I'll add that I've tried a lot of Olympus cameras over the last 50 years and I rate them all very highly. At times I'll rate them higher than Leica's lenses but I can afford the best from Olympus (like the Zuiko f/1.4 50mm and even the FourThirds 50mm macro) but can't afford or justify buying Leica's best.
A lot of people get wound up about the differences between the mju-I and mju-II but really they are slight. The II has spot metering and a faster lens but we all know that the slower one is no slouch. And f/3.5 when made by Olympus is brilliant.
Better still, you can find them for a couple of pounds if you look: that's about three US dollars or less in Euros.
If you like them with a zoom lens then look for the Olympus Stylus Zoom 80 Wide DLX which goes from 28mm to 80mm and isn't at f/11 at the 80mm setting.
Regards, David
