need help on jupiter-9

[fabrice]

Hi there, you FSU RF freaks 😀
I started shooting with a jupiter-9 on a zorki 1. ha ! I know it's bulky and not very cute to see ...
But I'm waiting for a zorki 6 that should be better I reckon.
Anyway : I got stripes, milky ones, horizontally. Sometimes one, often two, on some pics I made with the j-9.
I first thought of light leaks on zorki's body.
Now, I shooted in the same conditions, the same minute, with a j-11, that's perfect.
I guess it's some kind of flare, I didn't use any sun shade.
But I wanted to be sure.
I peeked through the lens, from rear, and found that the subject aimed was pictured, like a ghost, in the rear lens. Is it normal ? Is it somethnig that can be fixed ?
thanks !

Hi,
There are instructions for dismantling a J9 here. If the focus unit is OK, you will only need to take the lens unit off to unscrew the rear element to clean it.

Could you post an example of the problem shots? You might want to be sure that it is not a film or processing problem before you actually start dismantling the lens. It is one of the harder ones to work on.

Hi and thanks for the helping hand.
Of course I'm not into fiddling in it just for the fun.
Especially knowing it's ok and giving accurate aming !
I first thought the process was wrong, I must confess it was a cheap one 😀
So, I tried the best lab I know in town (hu, twice the price, you bet they are good !) and the problem stays the same..... anyway, my other pics (with J-11, and J-3) were so good with that lab I'm gonna stick to this one !

Anyway, it couldn't be a light leak while changing the lens, could it ?
I don't seem to find the same issue with other lenses.
Mind puzzling it is :bang:

edit : I can't show you a pic, don't have any scanner !
