[QUOTE="Bob Blaylock, post: 584274, member: 16749"] I recall seeing some discussion elsewhere on this forum, but don't remember details; about the possible issue of limits in the way the shutter-count number might be stored. I don't recall which cameras were under discussion, or whether there was any consensus about this limit. To give an example of a possible issue, suppose that an older Nikon DSLR used an unsigned 16-bit integer in which to store the shutter count. This would impose an upper limit of 65535. On the 65536th click, it would roll over to zero and start over. That's within a number of clicks that could plausibly be on a camera that old. If it used a 16-bit unsigned number to store the shutter count, and it really had 66,359 clicks on it, then it would claim to have only 823 clicks. If it used a 24-bit signed integer, then that limit would be 16,777,215 clicks, which is probably well above any plausible number for a camera to have. [/QUOTE]
