I saw the other day a Konica Pearl III, seemed fine when I inspected and I took a roll with it, results for shooting in the metro looked fine.
After bargain for the half I bought it (small hole in the bellows).
Winding works perfectly, loading is done as usual, shutter speed accurate (I tested all, 1 sec is 1 sec), opening has to be done carefully or it jams (still need to see why), closing is fine.
Bellows, at home I tested them in a dark room with the torch... Well I saw the milky way
I started to read about and I found a solution not hard to find here... Black paint for fabric + fabric glue + another black paint of fabric should resolve the thing, voila:
I tested again and no tiny starts anymore, I will check every week from now.
So one problem solved.
Second problem I detected, if I leave the camera for a while, the first shot the shutter blades are sticky and they take more than acceptable time to perform the open-close, but not happening for the next shots, I was amazed... Again looking on the net and from the rangefinder forum's web archive I found the clue:
Oil in aperture blades that went into the shutter blades, only to the inner part, nothing can be sought from outside. In this camera, the front lens is taken out just unscrewing it with the hand, then I put on B and I checked the aperture blades, yes, I can see oil there
So disassemble the lens has to be done to clean the shutter blades first and then aperture blades.
I'm stuck in this point now
That knob? in the up, can be twisted so the outer ring can turn about 10 degrees anti-clockwise:
And thats it, no clue how to take out that outer ring and I don't wanna try forcing and scratching things.
Any idea? I already tried to look for the konirapid-s shutter and the most I got is then its already opened, not the process...
Everything is welcome
