where got US410,000 that high? the bhphoto only selling USD10995!!!
hahaha.. i wish i will be that loaded to go for the noctilux! 
btw, there is no point to go up to f0.95. the DOF is too shallow. even for f1.4 sometime hard to get the subject fully covered if get too close.

actually for past year of search online, i found that Konica Hexanon is the best price/performance lens.
the lens are very sharp especially 50/1.7, where 50/1.4 have better bokeh. 57/1.4 slightly less sharp than 1.7 and 1.4 but the old lens colour rendition and bokeh is very nice.
those older Hexanon '70 and before have some kind of characteristic while maintain some high quality close towards Zeiss and even Leica.
Konica produced nice Hexanon lenses with highest quality at that era, with their own optical formula.
however, the hexanon are not that popular like Nikon and Canon, as their lens have shallower registered length than those lenses. So only a few camera can fit the AR mount, end up only Konica camera users. 
Of course they have higher range for Leica rangefinder, the ultimate M-Hexanon range!!!  
But now with Sony NEX and MFT camera, now we can enjoy this cheap but good quality lenses!!!
If you live in US, you might get it at very cheap price depends on your luck!!!
Here we have limited source for Hexanon, and the US shipping is really not pocket friendly!!
My advise for ebay bidder, you must avoid shipping with USPS First Class mail at all!! it is just normal airmail without tracking number and not registered. you end up missing in the hand of local post office!!!
Priority mail is better and Express mail is the best for tracking, and both will be handled here by poslaju EMS.

now the reason i want to let go most of my Hexanon not because it is not good, but I prefer to have my NEX in more compact size. Hence I go for Leica M mount lens which is the lens is very compact as well as thin adapter,  and it seems they fit the NEX body better than the SEL lenses!
I still couldn't afford the Leica M lenses which more than RM3k. So first I got the Voigtlander 28mm F2.0 which have very good review from http://www.kenrockwell.com/voigtlander/28mm-f2.htm!
