    Jupitar-9 is a 85mm F2 Rangefinder lens, Sonner copy, equal to a 170mm at 35mm terms on the micro four thirds. At 335g it is heavier than the GM1, so I am holding the lens and not the body. It fits better on GX7, G6 GH3 or EM1, but it is ok on EM1. It is a nice telephoto with wonderful rendering. It is a F2.0 lens that is bright and fast, in a similar range to the Olympus M.Zuiko 75mm F1.8, but not comparable to the sharpness.


    My copy is brought second hand, export model PT7060 manufactured in 1982, indicated by the serial number on the lens. It is in black painted aluminium shell.
    The aperture ring is stepless and the focus ring is very smooth and dampen. Much better built than my Jupiter-8. The glow disappear by F2.8, and it is very sharp from F4. Nine rounded blades aperture created round bokeh in the out of focus area. My copy exhibits very smooth transition from light to dark.

    On the micro four third system the bad edge performance is cropped out, so only the goodness in the centre is left on the image.

    I have a 1959 silver KMZ rangefinder version. I'd say it is sharp, but it has a rather low resolution (according to papers it is only 30 lpmm in the center), which might be ok for a full frame or film, but definetely not enough for mu43. Nevertheless I like the way it renders portrats. I also think that very high resolution images are not good for artistic portraits as you'd need to do a lot of skin softening and retouching anyway. Just a few recent shots I've done with it. All are done wide open.
