Test of my "new" Jupiter 12 for Kiev 4

[Dcanalogue]

Hi to all guys!

I've a nice (1967) Kiev 4 and wanted to give her a Jupiter 12. So, I've got a 1960 one, plus the KMZ 3,5 cm viewfinder.

Lens seems good but... there should have been a problem, because the results didn't satisfy me. There's a semi-circular halo in the center of the frame...:bang:

Check more on my Film Blog.

It might be a good idea to have the lens checked up, dirt or grease might have gotten from the aperture blades onto the elements.

I have a 1956 lens that would front focused badly on my Leica M4. Had to have its optical block adjusted to sit a few mm into the camera body.
I do not know the details though, because it was done by a camera shop.

It looks from some of your photos that your Kiev 4 might have a slight light leak ( not enough yak hair during re-assembly in the CLA) .

Some J-12 lenses tend to flare more than other J-12 lenses and year of manufacture or the factory that made them does not matter, that has been my experience.

If the Kiev with other lenses has no defect the most logical part is oil on the aperture blades or elements.

Well I can not complain because mine (J-12) was free of charge, sent from Ukraine.

I second this version...

Yep... I know the J12 is a great lens... as I have one M39 version.... 😀 Tested it by night too....

Yes, I have a J-12 M39 version too. Here tested on micro film.

Not bad at all. ATP1,1 in RLC / Film Low Gamma.

These are great. My J12 flares so badly, I only use it in overcast conditions.

The J-12 Kiev/Contax is a Black 1984 model. My J-12 M39 a 1973 Black model. I can not say there is any flare problem even a J-12 you can use without sun hood due to the construction of the lens. For any other Jupiter type lens you need a sun hood hood to prevent flare and reflection although the little later models have a slightly better coating.
