Hi Toomas,
A more modern approach to test shutter timing would be to use a
microphone and a computer sound card. If you use an audio editor
program that can display the sound waveform, it should be possible
to discriminate the sounds made by the mirror, the shutter opening,
the shutter closing, and the film winding. At least on the EOS 1000FN.

"Note added on 07-July-1999. Canon has revealed that the light metering
system of all EOS cameras uses 1/8-stop steps internally"
What was the source for this intriguing revelation?
