Barnack-toting Brit.
Comparing the two in terms of use, I think it's swings and roundabouts.I like the looks of the II's ad III's better but I understand that the IIa's and IIIa's are more competent. They are just lovely.
I was surprised by how much smaller the IIa was over the II. They feel much nicer in the hand, and the shutter speed selector is nicer to use.
The problem is the focus wheel is reversed in direction (which I just couldn't get used to), and the RF patch isn't central (it's lower than you expect in the VF - you can get an idea of how far the offset is by looking at the position of the RF window from the front).
