My 20D has been dropped twice and looks like a real workhorse with lots of scratches and missing paint ("patina", as Leica aficionados say) - but it is still going strong and has never shown any issues. I photographed violent rallies, children birthdays, sport events, casual portraiture and wild parties. My camera has seen use in tropical typhoons and freezing snowfall, at the beach, in humid jungle and busy city streets. It may fail earlier or last a lot longer.
As Henry said, it is impossible to say when a specific shutter will fail - they are not built to break down after 50,000 shots, only that Canon has rated and more or less gave you warranty that the shutter is built to last this number of shutter actuations. As I said, other people have noted this, too.Īnd you can well see, all shutters are different. If you like the number the program gives you, cuddle it, hug it, but don't believe that it is anywhere near the true shutter count. This is 100% wrong, I am sure that the shutter click count is somewhere around 80,000 - possibly higher.
Some of us know our cameras and know how much we use them.īut just for you, I did the exact procedure (with exactly the same XVI32 editor) as descriped in that weblog for one of my recent RAW files and it gave me the number of "shutter actuations" of 26865. Peter, why do you trust anonymous sources on the internet but refuse to trust some fellow photonetters? As me and a couple of other posters noted, the hex editor gives a number that is definitively, absolutely wrong. I believe it's a coincidence that a shutter failed shortly after an undocumented, purported "shutter count" approached 50,000 operations. It depends on the physical properties of the phosphor bronze material, manufacturing tolerances, differences in bend radii and surface finish. In fact, the Camera Shutter Life Expectancy Database is a really neat user-based site for DSLR models of several brands, including Canon. Individual shutters may fail at 5,000 operations, or one may go on to 100,000 operations. Typically this count is between 100,000 and 300,000 shutter actuations, with the latter limit associated with the EOS-1D models. The average life of a large number of shutters may be 50,000 operations. It is often measured using accelerated life testing which does not exactly replicate normal operation. In Canon's case it's more likely to be the number of operations exceeded by 50% of a sample, roughly equivalent to an average life. Life is often defined as the number of operations exceed by 90% of a sample. This is caused by metal fatigue.Ĭanon don't define shutter life they just state so many operations. The most common form of catastrophic shutter failure in the 20D is fracture of the moving contact in one of the shuuter curtain travel switches.
