Here I used a vintage Jupiter 9 85mm.f1.5 with my A7iii on a tilt adapter. Notice how the foreground grass is in focus despite the model also being in focus. Also, the background bokeh is heterogeneous, transitioning from larger bokeh balls at the bottom to small ones on top. The rainbow lens flare is also typical of these soviet lenses. The ghosting most visible around is flowers is because of the weak flare resistance of these early coatings. These rich characteristics aren't seen on modern lenses. If this image were shot on a highly optimized modern lens, I don't believe the result would be as interesting.
The Jupiter 9 was made using patents for the Zeiss Sonnar 85mm f2.0 that were seized by the soviets as war reparations after WW2.
