I have just won the Flektogon (including both the original end caps), on ebay UK for around C$142 shipped, that's about C$310 less than I paid for the DA 35 Macro (inc tax)...
I can't see it being anywhere near as flexible a lens (no AF, limited metering etc), but am looking forward to seeing how it's bokeh and colours, and sharpness from a tripod compare...
I won't actually get my hands on the lens till July but after that I'll post my thoughts about this my first screw mount lens.
There's ALWAYS another lens
