Spurred by Rob Studdert's fantastic results with his 125 f2.5 Voigtlander Cosina Apo Lanthar, I thought of reading up on what else Voigtlander offered.
Amongst the cheaper lenses, I noticed the 19-35 3.5-4.5 Ultragon was coated with VMV or Voigtlander's own coating www.voigtlander.com. Also, I understand that the ones rebadged under the Cosina or Vivitar label are essentially the same lens. My question is this: Do they all use the same coating? b&h and Adorama don't seem to stock the Voigtlander version, so I couldn't check if there was a price difference. Anyone?
