Now that I have put a dozen rolls through the Iconta - I like the camera but am unhappy with the lens - the Novar is nice and sharp in the center but even stopped all the way down is only marginal at the edges. I think one day I will sell it and replace it with a 6x9 folder with good edge to edge sharpness. Which one is that ... is it only the Heliar version of the Bessa?
