My third collectible Soviet lens is the Jupiter-9 85mm f/2 MC, a lens with a strong lineage tracing back to the pre-war Carl Zeiss Jena Sonnar 85mm f/2 made for Contax RF cameras. This particular copy was manufactured in the late 1980s and features MC multi-coating. Although the exterior shows heavy signs of wear, the optics themselves are actually quite clean. When I first received the lens, the aperture scale and index mark did not line up correctly. I spent quite a bit of time disassembling the entire optical block and aperture ring, then recalibrated and reassembled it so that each aperture marking now aligns perfectly with the indicator.
The most distinctive characteristic of this lens is its rendering wide open: contrast is very low and the image appears soft and dreamy, but once stopped down, the contrast improves significantly. In the first photo, the background blur behind the uBike bicycle seems to “melt away” into the distance, while the highlights carry a slightly creamy texture with a hint of swirl, producing an exceptionally smooth bokeh.
我收藏的第三顆蘇聯鏡頭是Jupiter-9 85mm f2 MC，與戰前的CONTAC RF相機接環的Carl Zeiss Jena Sonnar 85mm f2有著濃濃的血緣關係。這顆鏡頭是上個世紀80年代後期製造的，有冠上MC鍍膜，雖然外觀磨損的很厲害，鏡片倒是蠻乾淨的。這顆鏡頭剛到手時，光圈環的數字和指標位置有些差異，我費了一些功夫拆下整個鏡組和光圈環，將光圈環重新鎖定在正確的位置，讓每個光圈環的數字和指標都能對得上。
這鏡頭最大的特色是在光圈全開時，反差很低、很柔和，但縮光圈後反差也就好很多。第一張照片uBike腳踏車背後，散景一路往後「化開」，高光邊緣帶一點奶油感與旋轉感，非常滑順。
