Hi everyone, this is going to be a bit of a story but in the end I'll tell you a secret how to gain and use the best vintage camera you could possibly own today i.m.h.o: A Retina IIa with a Ultron lens in my opinion of course was never a regular combo as it simply hasn't ever been marketed like that. But: If you just read Mark Hansens comments about his expieriences with repairing those extremely complicated Voigtlander Vitessas - a fact I couldn't agree more to as well - one can easily imagine that someone who has seen the extraordinary results possible with an Ultron lens only once, its not surprising that someone who was fed up with fiddling had simply tried to put it on to a far more reliable body (today!) as the Kodak Retina for sure is! At least after I'd seen this one off camera offered on Ebay I immediately thought 'Wow, that's it!' and you guess it: I looked at my Kodak Retina II (Type 011) carrying a Schneider Xenon lens in a Compur Rapid shutter that's got lots of deep scratches by a cleaning maniac who owned my camera prior to me. I also knew that the very first Vitessas had a Compur Rapid Shutter also with an Ultron 2/ 50 mm lens in it. So what I did was simply to screw off BOTH elements of the Schneider lens, i.e. the front and the back lens and replace it with the font and back elements of my Vitessa A (!) This is not a cheap solution to come by if you must buy both cameras in the first place but its extremely rewarding in the end... just view my attached 'flowerchopper' foto....
