You gave the 50 lex ASPH.?? So how did the store pay for it, was it a good price?
I bought it as my first permanent lens for the Leica M system two years ago.
It has been the lens, that stunned me about the Leica lens quality and made me sell almost all my Nikon gear, while building a nice Leica kit.
It has been my favorite lens back then on BW film and the EPSON R-D1.
Over the last year or more, I didn't use this lens (right after it came back from a full CLA @ Leica Solms).
I bought a Noctilux f1, when the Lux ASPH was away and fell in love ;-)
The ASPH never had been touched since.
I bought mine, before the world knew about the Leica M9 for 16000¥ and sold it last week for 23000¥.
The shop will probably sell it for 26 − 28000¥ I guess.
I never liked the focus feel of the 50 Lux ASPH and consider it a design flaw - the optics though are exceptional!
I am very happy with the deal so far. It looks, the Konica might spark a love for wide angle lenses ;-)
