Some walk-around shots at the Marine Museum at Quantico, dropped Nicole off to class and got about 2 hours of visiting the Museum and taking a walk around the outside memorials. Great place to visit, and the most of the characters and lighting is repeatable.
This Canon 5cm F2 is much better than I thought it would be. It's a classic 1-2-2-1 double Gauss, like the Leica Summar. The diameter of the elements is wider, ~27mm for the Summar and ~30mm for the Serenar. The diameter is close to the Summitar, which in addition to the wider-diameter elements split the front element into a cemented pair. The wider elements reduce vignetting at the corners of the image, more noticeable as color films became popular in the late 1930s- as per the "Leica Manual" by Morgan and Lester.
Comparison with the Summar and Summitar will be for another day.
Today- it's Canon vs Nikon, battle of the 5cm F2's. The difference- Canon quickly moved from the F2 lens to F1.9 and then F1.8. Nikon kept the F2 Sonnar based lens in the line-up throughout the Rngefinder era. I took a relatively early 5cm F2 Rigid, left the 5cm F2 collapsible at home. Next time- the collapsible Nikkor and Canon were manufactured very close to each other.
