"Eight is Enough"- of Carl Zeiss Jena 5cm F1.5 lenses, that is.
1934 Carl Zeiss Jena 5cm F1.5 Sonnar on the M9, perhaps the first batch that can be converted to Leica mount using a J-3 focus mount.
1935 Carl Zeiss Jena 5cm F1.5 Sonnar, front element is Coated- first Sonnar that I converted to Leica Mount.
1936 Carl Zeiss Jena 5cm F1.5 Sonnar, uncoated- very sharp same batch as the one next to it.
1936 Carl Zeiss Jena 5cm F1.5 Sonnar, all surfaces are coated- a few lenses from this batch were pulled to try out the new coating equipment.
1938 Carl Zeiss Jena 5cm F1.5 Sonnar T, fully coated and marked with "T" for transparent
I converted these five lenses to Leica Mount.
These three are original Leica Thread Mount.
1943 Carl Zeiss Jena 5cm F1.5 Sonnar "T", recomputed optics, new metal alloy fixtures, original Leica Thread Mount.
1945 Carl Zeiss Jena 5cm F1.5 Sonnar "T" on the Canon 7, note "black nose" for filter ring, original Leica Thread Mount.
1946 Carl Zeiss Jena 5cm F1.5 Spnnar "T", post-war lens, "transition lens" as I call it. I needed to replace the middle triplet on this one, the original was unfinished.
All of these required hours of work to restore to usable condition. The 1945 lens has a helical that was so worn, and had so much slop in it- I had to make a guide tube to fit around the mechanism to stop the wobble.
So- problem? 'I don't have no problem!'.... "I'm a Sonnar Expert"...
Where do you go for the most extensive advice on the New Jupiter 3+? To the Jupiter master of course! Engineer and rangefinder enthusiast Brian Sweeney is well known as an expert on the Jupiter 3 and vintage Zeiss Sonnars, and we had the chance to speak with him about his experience with our newest art lens.

This one is way out of date...
I'm very happy and proud that this new company is offering service on the Jupiters and converting Sonnars to Leica mount.
