Why shutter DSLR cameras have an age limit?

Shutter unit

       This question often appears in discussions on forums or discussion starters. Digital cameras are no longer wearing postscript films often imagined as a camera that can be used continuously without limit. Snap at will, see the results, not like ya just stay clear. Without realizing the number of photos we've taken in the thousands in just a moment. It does not hurt much less for reasons of learning photography, but if we just take pictures for fun only, then do not use DSLR camera. Why, because DSLR cameras have a shutter unit age restricted.

      The answer is clear from the title above, because the shutter on a DSLR camera however is still the same as film SLR cameras, a mechanical shutter is electronically controlled despite having yet to work opening and closing vertically each photo was taken. Shutter movements are what caused the distinctive sound of a DSLR camera when shooting. Many who do not yet know if the shutter is when continuously used someday be broken (jammed or not working). The story is common when a person is buying a new DSLR camera she was so overjoyed shooting at will and suddenly he was surprised to learn that the DSLR shutter there is a limit, then imagine how many photo dihambur squander in the past.

       shutterunitUsia shutter (Shutter Count termed) is no one can be sure. The factory is only designed shutter unit and up to a certain amount of testing and released the results in a DSLR camera specifications. Cameras beginners class passed the test up to 50,000 times of use, while the camera on top of the class could reach 100,000 times even up to 300,000 times. This figure is not binding, there is a beginner camera that can surpass the 50,000 and there is also a new 25,000 damaged. To see how many times a DSLR camera is used, see the shutter count on the EXIF ​​data.

       The question next is, why such a mechanical shutter is still needed in the digital SLR camera? Whereas a regular digital camera ranging from camera phones to prosumer cameras use an electronic shutter to rely on sensor alone. No other answer is because the sensor in a DSLR camera can not do a 'gating' or on-off without the help of the shutter unit. When the shutter is closed, the sensor has a condition 'dark' and when we take the shutter open for a while (corresponding shutter speed set by us or the camera) and then closes again. From the first dark dark toward second that triggers the sensor to work. In the future could have a mechanical shutter is not used, if the producers managed to design an alternative that is cheaper but still reliable.
