Large Format Photography DELAYED!
I have four large format cameras and also medium format film cameras in my collection, and over the years have collected over 20 lens-shutters for them.
Recently, I purchased a shutter speed tester and took the time to test every lens.
Every one of them had shutter speeds so inaccurate and slow to make them useless except to waste time and expensive film if used for photography.
So, they are slowly being sent off to technicians for cleaning and lubrication, which should restore their factory specs. Camera shutters are like mechanical watches, though not as complex or miniaturized, but require similar servicing.
It will take close to two years to service them all, unless I can learn how to do the work myself. The attached photo shows a simple shutter. The large mechanism at 8 O:Clock controls shutter speeds and is the main culprit requiring cleaning and lubrication.
