...............Also there has been some candid fantasy around about detensioning the shutter lower drum in order to get a a silent camera. Given that this is what does it for the shutter speeds adjustment, wanting to use that to get a silent camera is not good because in many cases a very silent Kiev will mean a Kiev with too slow high shutter speeds (not faster than 1/300 @1/1250 and about a real 1/80 @1/250, while a properly tensioned Kiev shutter can have a 1/1250 setting doing it for a good 1/800 which is very acceptable)........................
I think the abovequoted statement is worth a good thinking.
Even better, for our good luck, we can test and get conclusive results. For some of us using negative film, instead of slides, some relative byas is not the most relevant since there are many factors, already byasing and absolute correct exposure. Nevertheless, none of us want that any of the speed settings (excluding the highest 1250) will go ridiculously or unusefull unacurate.
So in order to test a home (or Oleg) distensioned sutter, we know that 1 stop is 1 stop, therefore our test can start with setting our camera at a permanent shutter speed and create a series of exposures in which we alter the combinations of speed and aperture, leaving the same basic EV. Our results should be seen in the film as a constant density.
True, if we want to be more severe in our testing, a simple observation of the processed film will not be enough. We should print at a constant time paper exposure.
Furthermore, we can even perfection our test by choosing our most trustable non-Kiev camera, perform on the same film the EV test, and compare its results with those of our Kiev, either at the level of processed film ovservation, or at the printing stage.
It would be of the highest interest to me to perform this test the first opportunity when time is available.
Ooops !, I almost forgot, if anyone is going to perform this test, don't forget to test your Kiev before the distensioning stage, i.e. with the shutter tensioned as it comes beforehand. This may be of great interest too.
And do not forget, that the distensioning stage, as always said, must be on the basis of a perfectly clean and lubed shutter mechanism.
Personally I am not going to perform the test tomorrow morning, but I keep it in mind. So far my Kiev exposures have been "OK", in the spectrum of my EV variations, but I openly reckognize a propper test is due.
Cheers,
