The amount of breakdowns involving modern DSLRs, specifically the shutter and reflex mirror box, made me realize that inspite of modern marketing mayhem involving more Megapixels, more FPSs, more ISO thresholds, more features etc… these camera manufacturers have failed to develop further the number one bread and butter of a DSLR: The Shutter Mechanism.
The shutter mechanism and reflex mirror box of any DSLR is the most run down component of the camera. It is also the number one cause of failure due to common usage, apart from external damage caused by liquids or physical shock.
I recall these shutter breakdowns never occured during the film era on SLRs.
It was then that I answered my own question:
Film SLRs flick the shutter only 24 to 36 times per roll…
Digital SLRs flick the shutter about 1,000 times on a good day of shooting.
