Curiously, the IIc on the lower left below has a maximum aperture of f2.8 while the earlier II and IIa models and the later Retina Reflex all offer an f2 maximum f-stop.
My opinion is that the Xenon lenses on the Retinas were as good as anything being made in their time, as was the general design and construction of the whole camera line. Kodak continued for a couple decades to develop the Retina cameras, incorporating additional innovations including coupled light metering. However, the improvements were quickly matched by Japanese makers who were also ultimately able to attain an insuperable lead in price competitiveness.
I have seldom posted landscape images on the blog. My excuse has always been that I am just not good at seeing the compositional possibilities of the broad view. That is probably not true, though. I likely have just as much (or as little) talent for landscape as other forms, but I just haven't made an effort in the past to come to grips with the challenge. So, my plan is to start devoting a few frames of every roll of film to landscapes to see if I can develop some actual practical skills.
And, lastly, a goodbye to my loyal friend, Rio, who patiently endured many photo sessions, including this one with a Retina Reflex.
