The most common type of shutter has two curtains. Pictures are taken when the camera is connected directly to a computer (without a flash card inside). Mechanical shutters are found in all DSLRs and most mirrorless cameras today. The perceived shutter count is 2001, whereas the real shutter count is 9001. Most shutters are rated to a minimum of 150,000 (entry and mid-range DSLRs) or 300,000 (. The next picture file written by a camera like Canon 5D Mark II will be IMG_2001.JPG. Shutter count is an estimation of how much the camera has been used. The two largest (and most important) moving parts are the main reflex mirror (the mirror that allows you to look through the lens from the viewfinder and that swings up and out of the way when you take the photo) and the shutter. 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. Why the Shutter Count Matters DSLR cameras, like the SLR cameras they replaced, have very few moving parts. 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.then see if camera is connected by using: gphoto2 -auto-detect. To be actuated is just a fancy way of saying to put into action. The shutter count in this case will be only 3751. connect your camera with USB cable, for 6D model you have to disable the WiFi first. The shutter count of a camera is the amount of times the shutter has been actuated. 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.
