Today the long awaited Jupiter 9 for Kiev 10 / 15 arrived from Ukraine. It is in perfect condition.
I think you have to take the risk to order from UA. There you can choose between a handful offers of cameras in good condition. In Europe they are not very often offered. If you find one they are described as broken or untested.
I would not buy a broken one. The fan blade shutter is complex. Right now is a 1€ Kiev 10 on ebay with open shutter. I would not bid on it even if I could get it at the starting bid. 20 € postage is too much, except you want a shelf queen.
Here is a photo of the Jupiter 9. It is really in beautiful condition.
Last weekend I put a film in the Kiev 15. The weather was fine, thin clouds and soft light but good contrast and sometimes a little bit of sun.
I used my Gossen Digisix to compare the reading of the cameras light meter. The light meter of the Kiev 15 gives correct light but only as long as you cover the eye piece with your eye. As soon as back light comes in it is off up to 5 steps or more. I'm wearing glasses so I normally always get back light into the finder.
