Reacquired the CV 75/2.5 Color Heliar. I owned and sold it while I was using the K-7. I just bought it again to test because when I reacquired the Nokton 58/1.4 to try out on the K1 (which I'd also used on the K-7 and K-3 but sold), the Nokton metamorphed into one of the finest lenses I've ever used, as though it needed a better sensor to really show its stuff. First shots on the K1 suggest the same is true for the CV 75, and well lives up to its name
color Heliar.
Here's a shot at a local fruit market wide open:
Shot below shows it is sharp from corner to corner at f2.5 as well. Full:
