The polish dealer “Infoto” sold six NEW(!) Voigtländer Nokton 25mm f/0.95 lenses for 599 on eBay (Click here). Sadly they sold all lenses within a couple of minutes! But as I told you the price of the Nokton is falling and expect more such deals soon! BY the way Infoto is a well know and trusted store that is also selling the new Samyang lenses: The 7.5mm fisheye (Click here) and the Four Thirds 35mm f/1.4 lens (Click here).
Reminder: A full review of the Nokton is available at Photozone.
