>>How does the lens on the Olympus XA compare to this one?
I don't own the Contax, but I have owned the XA since it was new... and the lens is not that sharp, at least mine never was. It is a fine camera (really well designed... and amazingly futuristic for the time), but the lens is only ok. 8x12" prints are fine, but nothing to wow you... good enough to still be serious. The lens also seems to fall off at both ends more than most cameras... and f5.8 seems to be the sweet spot. Defraction seems noticable at f11 and horrible at f16... and it soft at both f2.8 and f4... but still usable. My Minox GL and Epic Stylus both smoke it for IQ... though I have shot many good photos with the XA... hope that helps. I've always wanted the Contax, haven't stumbled across one for a good price yet...
