Voigtlander Accessory Rangefinder

I don't have a lot to comment. This is the gadget to deploy when you are using a rangefinderless camera and you really want a rangefinder.

This Voigtländer model is small, well made, accurate and smooth in operation. What else do you want?

And it's pretty too. Zeiss Ikon's rangefinder, for instance, is much clumsier and uglier.

Pity that this one partially covers the release button on my Altix...
