are contax mount jupiter-3s better quality?
No- not that easy to sort out. "Overall", quality between the two is the same. The Contax mount is much simpler, less to go wrong with it. The Leica mounts- I've seen some that are perfect, some that needed the helical repositioned in the mount to drive the RF to infinity. Optically- production went from KMZ (Trapezoid as shown), to ZOMZ (triplet and Eyeball Logo), to Valdai- as shown. I've found that the first year or so within each company, quality varies. By 1951, KMZ hot a good stride. By 1958, ZOMZ hit a good stride. Valdai: all over the place.
Back to the safest bet is to buy one from a forum where someone actually can show pictures taken with the lens.
