The Voigtländer site takes quite some time to update occasionally; more to the point, it's not until the new lenses go on sale that the Voigtländer site is updated, usually.
I've taken a good look at this lens; FM already has quite a nice review of it. But I'm sticking with one of my favourite lenses, the Summarit-M 75mm f/2.4. I simply don't need anything else. I'd find it hard to resist if I did use the 75mm focal length more often, though.
