With digital SLRs, we no longer need to worry about expensive film. We just click on the shutter button repeatedly until we get an exposure that we want thinking that we have this unlimited number of shots. We think that we're only limited by the size of our memory cards. But, is that really the case? Can we really continue to press on that shutter button as much as we want without worry and without wearing out our cameras?
I found out that this is not the case after all. In time, our camera's shutter mechanism will start to wear and bug down. At first, that got me worried. There even came a time that I would no longer take that "useless" shot for fear of adding life to my camera's shutter mechanism. So, how many clicks does it take before the shutter mechanism will fail? I tried to search for the life expectancy of the shutter mechanism for my Canon 1000D and I found out that there is no determined/fixed shutter life; some died sooner than others. I found a great resource and you can check it out from the link below:
http://www.olegkikin.com/shutterlife/canon_eos1000d.htm
From that site, survival estimation (Kaplan-Meier) rated 85.7% at 25,816 - 32,637 shutter clicks.
I bouthgt my Canon 1000D at Php 32,000.00 at the Canon store in SM Northwing, Cebu. If my camera's shutter mechanism would still be alive at 32,000 clicks, or even if it died at that number of clicks, that would mean that each click on my shutter button would just cost me Php 1.00. That's really cheap considering that the memories we preserve when we take pictures is priceless. So, to those of you newbies like me who may be worried about your camera's shutter life, DON'T! Continue to click away on that shutter as each click on that shutter is another learning experience to improve your craft and freeze an important memory in time.
The data from the link I posted above is mostly derived from people who go to their page, indicate their current number of clicks, and indicate if their shutter is still alive or dead at that number of clicks. The more people add their data, the more accurate the figures will be. So I encourage you to also visit the page and add your data there. For your convenience, let me post the link again:
