>>3242756I like the contax Sonnars and the russian copies.
They're nice people lenses, especially the f/1.5 ones (Jupiter 3).
Soft wide open, really smooth bokeh (13 aperture blades) and great separation at f/2-f/2.8 because of field curvature, and at f/4-f/5.6 you get that 3D pop because it's very sharp and contrasty in the middle and sharpness gently falls off towards the edges.
Stopped further down, they're sharp across the frame and good all around lenses.
Also tiny for the aperture.
The f/2 versions (Jupiter 8) have more or less the same characteristics and are dirt cheap.
But unfortunately the only adapter that works costs a lot.
