What is eosmsg? Why is it called a refurbished camera detection tool?

eosmsg is a professional refurbished camera detection software whose results have been recognized by official platforms such as Chinese courts. It can accurately detect core usage data of mainstream camera brands including Canon, Nikon, Sony, and Pentax, covering parameters such as model, serial number, shutter count, mirror count, mechanical shutter count, and CMOS dead pixels(The detectable items may vary among different models). Uniquely, it supports querying the historical maximum values of key parameters like shutter count, mirror actuation count, and mechanical shutter count, effectively identifying parameter tampering and helping users detect refurbished cameras. Additionally, the software also provides one-stop management functions such as firmware upgrades, remote shooting, copyright information, and time zone settings for Canon cameras. It combines professional detection and practical tools, making it a reliable choice for second-hand transaction verification, camera status evaluation, and daily device management

FAQ

I clicked the shutter button, but the displayed shutter count did not change.

It is necessary to power cycle the connected camera (turn off and on) in order to see the updated shutter count value. This is due to a technical optimization that minimizes battery power drain when a camera is connected to eosmsg.

Why not use the picture filename to determine shutter count?

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).

What's the difference between shutter count and mirrorup count?

Due to the real-time viewing and video shooting the shutter is in a normally open state, the mirrorup count and shutter count may not be equal.

How to identify refurbished and repaired cameras?

DSLR: Under normal circumstances, the number of mirror should be roughly equal to the number of shutters. If there is a significant discrepancy between the two, it is abnormal. Whether it is the number of shutters or mirror, their historical maximum values should be equal to the current value. If the historical maximum value is greater than the current value, there may be suspicion of refurbishment or repair.
MLC: Generally, whether it's the number of shutters (mechanical, including the front curtain) or the number of shots taken (mechanical + electronic shutters), historical maximum data should be less than the current number. If the historical maximum value is greater than the current value, there may be suspicion of refurbishment or repair.

In addition, cameras with data altered by Someone may appear normal during initial inspection, but after being used for a period of time, the data may be restored during subsequent inspection, resulting in abnormalities. Therefore, it is necessary to consider multiple factors when judging refurbished cameras that exhibit abnormalities.
