Sorry if this subject has been already treated - in that case, I'd appreciate if someone could link me the proper post.
How easy it is to reset the shutter count in a camera? I'm always buying used stuff (in this case a 5D3), and I would like to know how trustable it can be.
I perfectly know that in Canon they sell refurbished cameras with shutter count of 0, and in custom firmwares (self compiled) you can reset to zero the counter, but they are both operation that require much more skill than a normal user can have.
Thank you in advance for your replies.
1. You cannot reset the shutter count to zero. I have never heard of anyone doing custom compiled firmware, you need to have the source code first.
2. Canon refurbs do not have the shutter count set to zero unless the motherboard has been replaced, which is rare. This is because a new or refurbished motherboard is reset to zero.
