1/2" B4 lens test; bought this Fujinon Lynx III S18x6.4 BERM-16 1:1.4/6.4-115mm for £25 on eBay and made a M4/3 adapter for it by cutting down an M4/3 macro tube.
Considering the lo-fi adapter, the results aren't that bad, but I'm not sure I want to be spending nearly 10X as much as the lens to buy a real adapter for it!

Hmm…it looks like things are taking a while to load. Try again?
