Shutter speed testing device
My buddy "buetts" buetts gave me this brilliant little aparatus that listens to the speed of light. I have no idea how he did it, but all you need is the free software Audacity and this little black box [http://www.flickr.com/photos/buetts/8515982132/in/photostream] to test all your cameras.
Once you've downloaded the software, plug in the tester. Then you need to have a strong light in front of the lens. This is best done with anything to lay a torchlight on (and don't have a "helper" who's constantly complaining about this and that and gnagnagna).
Make sure you have the setting on your computer so that the "earphone"-plug is on "input"!
Switch the box on, start a record in audacity, and fire the shutter. Stop the record, go backward in it to search for the peaks and measure from start to stop.
Buetts has made a litte video to show the procedure : [http://www.flickr.com/photos/buetts/8516184497/in/photostream/]
Now that I know, how it works, it is a breeze. Easy. And super-exact. I\'ve tested some of my cameras and found that the Kiev/Hartblei is the most exact. Almost to the spot.
For example: 1/125 is 0.008 sec. The Kiev is on 0.009 sec. My Pentacon Six is (same 1/125) on 0.012 sec. Which is still close enough.
Buetts buetts sells these devices, so if you would like to have one: get in touch with him.
