Voigtlander Prominent, 3 lens. A Skoparon 1:3.5/35mm, Nokton 1:1.5/50mm, and the Super-Dynaron 1:4.5/150mm. was wondering around how much these go for and where would be a good place to sell, i have to pay rent and this is the only nice thing i have, and was wondering if these are still going up in price, any advice would help alot and thank you very much.
