Typically this count is between 100,000 and 300,000 shutter actuations, with the latter limit associated with the EOS-1D models. Usually, you’ll have to take a couple hundred thousand photos before this happens though, and Canon has allegedly released a particular shutter actuation threshold to indicate the number of shots expected for each EOS model before the shutter fails. At this point, you may either need to have the shutter replaced or purchase a new camera. Sooner or later, your DSLR’s shutter will wear, slow down and eventually stop functioning. Just as with any piece of mechanical equipment, a camera has a lifetime that is based on the number of shutter actuations otherwise known as shutter clicks or the shutter count. Pictures are taken when the camera is connected directly to a computer (without a flash card inside).Shutter Count Number is important – A DSLR’s shutter will eventually fail.The perceived shutter count is 2001, whereas the real shutter count is 9001. The next picture file written by a camera like Canon 5D Mark II will be IMG_2001.JPG. This results in a much lower perceived shutter count than the true shutter count.įor example, let's say the filename is edited from IMG_9000.JPG to IMG_2000.JPG. Some cameras, such as the Canon 5D Mark II, will use the card filename to construct the name for the next picture. The file name is edited to lower the numerical suffix. If a blank flash card is inserted afterwards, some cameras like the Canon 60D will continue previous filename numbering for example, will write file IMG_4102.JPG when shutter count is 3752.The shutter count in this case will be only 3751. If a new flash card is inserted with a file IMG_4100.JPG, then the next picture taken with the camera will be written under IMG_4101.JPG. The numbering then continues with this higher suffix.įor example, if the last file written by the camera was IMG_3750.JPG, this indicates that the shutter count is 3750. A new flash card is inserted containing a picture file with higher numerical suffix.
Here are examples when the filename does not indicate the true number of pictures taken with the camera. Using numeric suffix of filenames written by the camera on a flash card is not equivalent to camera's shutter count (the suffix resets to 0 after 9999).
