The Jupiter-8M arrived well-packed and exactly as described - clean, and optically-mechanically excellent. It fitted nicely to my prewar Contax II. In use, the Jupiter-8M produces pictures with sharpness and tonality equal to the prewar f/2 Sonnar, but with higher contrast and flare control, due to factory-applied coatings. Image quality is surprisingly good wide-open, and improves as the lens is stopped-down. The build quality is also very good. It is a wonderful lens for Kievs and Contax cameras at a budget price. Yuri also answered all my emails quickly and politely, and the buying/shipping process was handled excellently.
