What is Shutter count in DSLR?
In basic terms, shutter count is nothing but the number of pictures clicked by the camera.
In technical terms, it is the number of actuation made by the camera shutter. It is related to the camera body since shutter forms the part of camera body.
How Camera Manufacturers Calculate Shutter Count?
Camera manufacturers derive the shutter count value for each camera body series based on the shutter reliability test. They will put the shutter for a stress test to check after how many activations it starts to fail?
They will do the tests on multiple shutter samples. The value is derived from these results.
Why is Shutter Count Important?
Every camera body comes with a defined shutter count. Camera manufacturers give a specified shutter count value for each camera model.
The shutter would work reliably up to this value. So, the manufacturer specifies the camera warranty up to this value. If anything happens to the camera shutter after this value, you will have to get it replaced at your own cost.
Shutter count for a high-end full-frame DSLR like Canon 1DX Mark ii is 4,00,000 whereas, for a high-end Half frame DSLR camera like Canon 7D Mark ii, it is 2,00,000. So, shutter durability rating varies with models. High-end cameras will come with more shutter count.
Is it possible to Alter Shutter Count?
Altering the camera shutter count is a fraud. So camera manufacturers ensure that these values are tamper-proof.
They store the shutter durability values inside the camera’s internal memory. The user will only have read access to this memory and no write access. Thus they protect the camera from shutter count fraud.
How To Check Camera Shutter Count?
