Lovely photos with the Zeiss Jena Sonnar, the last few arboreal posts are wonderful, Steve!
Dare I say... tree-mendous? 😉

Very nice flower shot!
You mean for the 35mm reflex cameras, for the rangefinders there are more, such as Jupiters, Nikkors, Serenars and Voigtländers.
Main problem seems to be the focus shift. Nippon Kogaku made twelve optically different Sonnar versions before they finally went for the Gauss type.
Nikon made an f/1.4 version and an f/2 version. The f/1.4 version suffers from weak corners and the f/2 from distortion (my experience). I prefer weak corners over distortion.

the f1.5 lenses may have some coating damage or do they really loose contrast "that" easily?
Personally I have no experience with the Serenars, but what I know is that Canon used some chemical ingredient in the glass that causes haze.
The 50mm f/1.2 suffers from this too, unfortunately, because if not it would be a beautiful lens. It is not a Sonnar, however.
