I thought that perhaps when mounted on the camera body that perhaps the
light would be at such a sharp angle to the film that it would have no
effect , or be invisible as far as the film plane is concerned.
So I tested for this as well.
:-(

With the back open
and seeing what the film would see , there is no doubt that un-metered
light is entering the body through these lens openings.
It is the same situation both on the
Volna and the Arsat 80mm 's.
So what can you do about this ???
Sadly , not much at all.
It is simply a big design flaw that
is not easily overcome.
Some say , ¨remove the
lever and put tape over the hole¨ , but this is not the cure at all.
There is still a large quantity of
light entering the focus scale opening that can not be ignored.
The only options are ,
1. Toss the lense in the trash.
2. Don't focus on objects less than
90cm for the Volna and 100cm for the Arsat.
At distances greater than this the
light can not enter the body as the inner lens elements have now
covered the opening in the rear of the lens.

So there we have a brief introduction of
lens faults.
One thing to remember is that in the
case of Kiev lenses , you will rarely get a ¨perfect¨ lens.
All will have one or more fault as
exposed in these few pages.
A decision on your part will have to
be made as to where to draw the line of what is good and not good
enough.
This will be influenced to a large
degree on how much money you wish to spend on a lense , and if you can
be bothered getting repairs done to it.
Good shooting......
