Originally posted by lesmore49 A question that many will have on their mind. As others have indicated...shutter actuation's rated at 100,000. What about other components of the camera ?
Impossible to say.
After 100000 shutter actuations wheels may have been turned and buttons pressed anything from 120000 to 50 million times.
Depends on how the camera is used.
And: wheels, switches, and buttons often do not like NOT being used for very long times.
As far as I remember, in the LX Pentax used a lot of gold for contacts, and liquid mercury switches for the flash circuit.
