Recent Cameras with DIGIC 6/6+ like the EOS-1D X Mark II, EOS 5DS, 5DS R, 80D, 750D / Rebel T6i / Kiss X8i and 760D / Rebel T6s / 8000D do not provide too actuation count information. It seems that Canon has removed the shutter count functionality from the firmware. Oct 26, 2013 Shutter Count Number is important – A DSLR’s shutter will eventually fail. 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. Sooner or later, your DSLR’s shutter will wear, slow down and eventually stop functioning.
Shutter Count 7d IiUsing 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). Here are examples when the filename does not indicate the true number of pictures taken with the camera.
Shutter Count Sony
- A new flash card is inserted containing a picture file with higher numerical suffix. The numbering then continues with this higher suffix.For example, if the last file written by the camera was IMG_3750.JPG, this indicates that the shutter count is 3750. 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 shutter count in this case will be only 3751.
- 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 file name is edited to lower the numerical suffix. Some cameras, such as the Canon 5D Mark II, will use the card filename to construct the name for the next picture. This results in a much lower perceived shutter count than the true shutter count.For example, let's say the filename is edited from IMG_9000.JPG to IMG_2000.JPG. The next picture file written by a camera like Canon 5D Mark II will be IMG_2001.JPG. The perceived shutter count is 2001, whereas the real shutter count is 9001.
- Pictures are taken when the camera is connected directly to a computer (without a flash card inside).
