TESTING LEICA SM CAMERAS FOR PROPER FLASH SYNCH


To test if your camera synchs properly with a flash is no problem as long as you can open the camera back.  Looking at the frame opening of the camera while firing the flash at a bright surface will quickly reveal if the entire frame is exposed correctly.  But what to do with cameras that don’t have an opening back like all of the Leica screw mount cameras?

There is a very simple, non-invasive way to do so.  All one needs is a piece of so-called glow-in-the-dark-tape.  This should be noticeably larger than the frame opening of the camera.  Inserting it into the camera in place of the film is all that’s necessary.  With the lens removed, if possible, connect the flash to the camera, set the required synch speed and set off the flash, preferably firing right into the camera and then remove the tape.  In a not too bright area, the tape will glow with the outline of the exposed area.  This will quickly reveal if the entire frame is illuminated or if the shutter is covering part of the negative area while the flash is firing.

This test will work with all types of flash equipment.  Especially with cameras like the Leica IIIf, which have a built-in flash synch adjustment, this test can quickly determine the proper synch settings without the need to hunt down an instruction book.

  1. The Leica and cameras and photography in general certainly offer a lot of topics for discussion. But we must not forget the ultimate purpose of why we have cameras; to take pictures. For that reason I would like to start a weekly (or possibly daily) gallery of photographs. But I don’t want this to be a showcase for just my own work; to the contrary, I would like to encourage everyone to submit photographs for display on this blog. The copyright to the photographs will remain with the photographer and no pictures will ever be used for any other purpose unless permission is given by the copyright holder.
    No registration for this site is necessary. Just email any of the photographs to either of my email addresses at:

    info@gmpphoto.com or gmpphotography@msn.com

    If possible, please include the make and model of the camera (any camera, not just Leica) and any other information you deem important.

    It is my hope that this may become one of the most sought after topics of this blog.

    Thank you,

    Heinz Richter
