In most brands, the shutter count is saved in the Exif data of the photo. this topic is different to shutter ‘speed’ – see here.) Or maybe you just want to check and compare it with others so that you can price it correctly if you’re considering selling it.
Maybe you’ll find out that it’s time to upgrade your gear. You can use it to diagnose your own equipment as well. For example, if you’re buying a second-hand camera and you’re indecisive between two, you can use this information to decide which one to get. It’s important to know the shutter count because it will let you know how much ‘life’ a camera has.
The number of times a camera has fired is therefore counted by the shutter count. This operation can only happen so many times in the lifespan of a camera because these pieces wear out. Most of the time the camera shutter movement happens in fractions of a second, putting the mechanism into a great amount of pressure. In the case of DSLR cameras, there’s also a mirror that needs to move out of the way for this to happen. These parts cover and uncover the sensor allowing the light to ‘imprint’ the image. This is because every time you shoot a photograph, there are a few pieces on your camera that go into motion. The shutter actuations can be a useful way to gauge the longevity of your gear. If that is correct then right way to calculate number of shots are:Īnd then multiply x * 256 = total number of shotsīecause every 256 shots second number goes down by 128.Like any other product, cameras have a certain lifespan. as this result is pretty close to reality it is not exact because would imply more complicated math and it's not the case. Roughly if you take second number, substract 6400 from it and then divide the result by 64 and then multiply the result by 100 you will get a number that is very close to the real number of total shots taken by EOS 350d. So every 100 shots, camera increments second number by 64, at 256 shots it increments second number by 1 and resets third number. Opened file number 258 and found 32, 6529, 2 So third number goes until 256 and then increments second number and starts from 1 Opened file number 252 and found: 32, 6528, 252 Opened file number 199 shot and found the numbers like this: 32, 6464, 199.
Opened file number 97 shot and found the numbers like this: 32, 6400, 97. opened the first image ever shot with my camera (file number one) and I found this numbers 32, 6400, 1. I saved lots of pictures in my computer, including the first ones shot. At line 0093 in opanda exif viewer there are some numbers.
I am not sure if this refers to the EOSInfo software or the availability of that information in general
UPDATE (): Apparently, Canon has removed the facility for checking the shutter count on the 500D. It's not that I have anything against the owners of those cameras, but simply that the Canon SDK does not support retrieving the shutter count for them. The shutter counter will not be displayed (or will be displayed as "0") on the 1D*, 5D, 10D, 20D, 30D, 300D, 350D, and 400D. It will also show the shutter counter for the 5DMkII, but the camera must be power-cycled before the value is updated.
This means that EOSInfo will display the shutter counter for the 40D, the 50D, the 450D, 500D, and the 1000D. The shutter count information is available only on Canon DIGIC III/IV DSLRs except the 1D* series. Based on the notes on the EOSInfo website it seems that this information is not available for other models I tested it on 40D and 450D and it worked fine. I have used before EOSInfo Utility but I am afraid it only supports 40D, 50D, 450D, 500D, 1000D and 5DmkII. I am not aware of any available software that would give you the shutter count for Canon 350D.
