I bought 5 Zuikos a year or so ago, 24 f2.8, 2-50's, f1.8, 100, f2.8 and a 135, f2.8. I think some of the reasons they've become so popular, (expensive), is, yes, they do adapt well to DSLR's, (they work beautifully on my 40D as well as on my OM1's), they're small, light, almost all use the same 49mm filters, and they are optically excellent. What more can you ask for? Hence, the prices.
