Michael, my Sonnar is a Zeiss-Opton, meaning it was made in West Germany after WWII. I'd need to research its age, perhaps based on serial number, but I guess it's from sometime in the 1950s. Joe's is a pre-WWII uncoated lens. I'm not sure if there were any significant optical changes to the design, but the major difference was the use of lens coatings after WWII. My lens has Zeiss 'T' coating, which I guess is the precursor to the current T* coatings. Looking at the optics and one would think it was a modern lens compared to some other single-coated lenses from the 50s-60s with the predominance of a single coating color, like blue or amber. To complicate matters, after WWII Zeiss-Jena in East Germany also produced Sonnars... Jena was the original home of Zeiss, but after WWII it was broken up with many of the people ending up in West Germany but the factory and machinery/tooling and some parts being taken over by the Soviets, who apparently moved a lot of that back to the USSR and was the basis for the Kiev cameras/lenses, which from my understanding, are lower-grade knockoffs of the Zeiss designs. Apparently there are also 'fake' Zeiss Sonnars, which Joe might be able to better clarify. Here's a link: http://taunusreiter.de/Cameras/Zeiss_Fakes.html
Very nice images. You seem to use the 35 Cron as your daily-use lens. I really like the second image.
Edward - looks good! I agree, this thread greatly benefits from many talented photographers.
