I have recently gotten hung up on Kodak Retina rangefinders. Did some research on line to learn the different models and terminology. Decided to pursue the "II" models as they have no metering built in. Purchased a very nice IIa on E-Bay and ran a couple of rolls through it. I was very impressed with both the ease of use, the utilitarian simplicity, and the excellent results. Then I saw a IIc on E-Bay and thought I would try that. Very attractive price; its really amazing what excellent quality cameras you can find if you cull out the "good lookers but don't work" for the really hidden gems.
As it turns out, I enjoy the the IIc even more than the IIa, although I do like the the "old school" angelular lines of the IIa. It seems to me the IIc has a few mechanical improvement over the IIa, such as increased support for the lens board, easier to read f stop and SS numerals, and smoother "feel." Folded (that is what this group is about; bet you though I'd forgotten!) my IIc fits right into my left rear Levi's pocket, always ready for action!
The only further upgrade to my rangefinder Retina group would be a IIC (large C) which has the increased rangefinder window size and improved brightness. The only problem is that "English" versions are somewhat rare, and because of this, the "collectors" keep the value very high. You can get a really nice functioning IIc for $50-75, but I have yet to see a nice IIC for less than $300. Get the IIc and enjoy!
Although Retinas were never intended by Kodak to compete with "professional" cameras of their time period, they were built in Germany and build quality is surpurbe. Sturdy and robust; any of the Retina "II" series are a pleasure to use and a priviedge to own.
