Prices of Cosina-Voigtlander Lenses at CameraQuest from 2006 to 2011

Prices of Cosina-Voigtlander equipment has been rising since I started tracking it several years ago. I've put together this detailed list of the cost of lenses from October 2006 until 2011 as they appear/appeared on Stephen Gandy's website, http://cameraquest.com .

How to read the data:
- numbers highlighted in pink means the price has risen since the last time it was in stock
- numbers highlighted in green means the price has decreased since the last time it was in stock
- the price of the 75mm f2.5 didn't change but because it now included the viewfinder I considered that as good as a decrease
- data from October 2009 was unavailable and so it was not included
- this is not a complete list of lenses (eg the 35mm Pancake first version and 50mm f2 Heliar are absent).




My observations on the data:
- Since 2006, the 50mm f2.5 Sokpar has increased a stomping 107% from $289 to $599. This is the largest percent increase on the board.
- The 50mm f1.5 Nokton ASPH is in a hair-splitting second place going up 106% to $699.
- The lens that seems to gain the most ribbing for its unstoppable increases, the 28mm f3.5 Skopar, gained a meager 103%, rising to $579, before it sold out in 2010.
- In terms of US dollars gained, the fattest pig is the 35mm f1.2 Nokton ASPH (chrome version) that increased $476 before the final sucker purchased that last one. Wait? "Sucker"? Investor! I'm an idiot for not paying attention to my own data analysis! If that lens continues to gain value like this in a few decades the 300 people that own chrome noktons can buy Europe back from China
