Welcome to the Canon Rebel (EOS 200D-800D) Talk Forum, the place to discuss Canon's entry-level digital SLRs.

Shutter count will increase by one if you made a shot via viewfinder or even more if you made a Live View shot. Note that some newer EOS models (1D X Mark III, 90D, 200D Mark II, 250D, R, Ra, RP, R5, R6, M6 Mark II, M50, Rebel SL3, Kiss X10, Kiss M) report shutter count in increments of 1000 shots. Remote switch for EOS cameras with the N3-type socket. This remote switch has a self-timer, interval timer, long exposure timer and exposure-count setting feature. The timer can be set from 1 second to 99 hours. A new dial enables you to easily enter the numeric settings with a single thumb. It has an illuminated LCD panel and a 2.6ft/80cm cord. A couple of things to check with DSLR cameras is their MegaPixel count which describes the resolution, battery type, sensor type and size, and shutter speed. DSLR cameras with good sensor give you pictures that are sharp and detailed even when enlarged. A camera’s sensor size gives you an idea of how wide a view it can cover.

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). Here are examples when the filename does not indicate the true number of pictures taken with the camera.
  • 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).

This is a known issue that affects several Canon EOS models with outdated firmware versions. It’s caused by a bug in camera firmware where Canon developers messed-up a simple integer to string conversion by accidentally chopping the lower 32 bits of a serial number.

When ShutterCheck asks a camera about its serial number the special PTP (Picture Transfer Protocol) command is issued and device replies with a S/N in form of a text string. Internally in camera a S/N is stored as a 64-bit integer value, so an int-to-string conversion is needed. Imagine you have a serial number 63850724266. In a full 64-bit big-endian hex it would look as 0x0000000EDDCCBBAA. Because of the described firmware bug the lower 32 bits (0xDDCCBBAA) of the memory cell get chopped away during the conversion and only the 0x0000000E remainder makes it into the final string resulting in erroneous “14” serial number being reported back to ShutterCheck.

Tool

From our testing, the following cameras with specified firmware versions are subject to the S/N issue:
EOS-1D X (3-2.1.1), 5D Mark III (3-1.1.5), 5D Mark IV (3-1.2.1), 6D (3-1.1.9), 6D Mark II (3-1.0.3), 7D (3-2.0.3), 550D (3-1.0.9), 650D (3-1.0.1), 760D (3-1.0.0), Rebel T4i (3-1.0.1), Rebel T5 (3-1.0.1), Kiss X6i (3-1.0.1).

To resolve the issue you have to update your camera to the latest firmware revision. There is no way to fix this from ShutterCheck's side. After the update the reported S/N should match the label at the bottom of your EOS camera body.
