Kiev - dark corners on negatives and transaprancies

[donald_lush]

I have a Kiev 60 which I am very happy with but it has one problem I

can't work out. Processed film shows the corners of the film are

noticeably darker that the rest of the picture, especially the two top

corners. I don't think this is vignetting since it seems to be

consistent regardless of lens aperture and exposure.

I wonder if I've got a light leak (if it is, it seems to be showing up

in a rather strange way) or could it be that the pressure plate is not

properly adjusted and the corners are not being exposed to as much

light as the rest of the film? Any ideas welcome!

Donald-Are the dark areas on slide film or on the negatives and print

light?

Donald,

Maybe your mirror does not flip up enough? Did you modify the damping rubber for the mirror?

Does the problem show up with all of your lenses, or maybe just on one lens?

Donald, Vignetting is usually caused by an inappropriately sized filter or by stacking filters, or by an inappropriate lenshood. It can be consistent regardless of lens aperture and exposure value. Suggest you rule this possibility out first. Are you using a filter or filters, or are you using a lenshood? Try leaving them off and see if the problem goes away.

I have found, with my Kiev 88, that the factory-supplied lenshades

are all slightly too small (or slightly too deep!). Even without a

filter, they all vignette just slightly. With any filter, even the

thinnest, they all vignette visibly. I have had to modify or replace

all of them over time.

Thanks to the people who replied - three of you suggested the same

solution so I will try exposing some film without the supplied UV

filter and hood. However... after asking the question, I did some

more trials. It seems that the problem does not show up on negative

film at all (even with hood and filter)- ie no light corners on the

negs. I also realised that dark corners on transparencies mean that

not enough light is getting to the corner so the light leak is not a

possibility. Has anyone got any other ideas? Thanks again.

Does anyone know where to get hoods for Kiev lenses? I can't seem to find most of them anywhere ... in particular the ones I want:

Mir 45/3.5 (size 77) and Kalenir 150/2.8. (82) er... I don't fancy spending a small fortune on a Contax size 86 hood + adaptor for the Kalenir though!

Both the 150 and the 45 have 82mm threads. The best option is to get one B+W 82mm wide shade, and one B+W 82mm tele shade. They are available at B&H in New York for around $25-ish each. That's the easiest solution, and they work well.

 

The "OEM" Kiev shades are almost all too long, especially for the 65mm. I have replaced all of mine with appropriate B+W shades, with fine success.
