Can number of shutter actuations be rolled back?

The info I'm reading online says the Canon files from the 7D do not have the shutter count 'exposed' in the EXIF data for images from the camera. Rather, you need a utility installed to a computer and the camera connected so the software reads the shutter count from the camera body. And, the software doesn't seem to run on all computer types and operating systems. So how again, was this reported number obtained?

Use your common sense huh. If its only got 158 clicks its gonna look like a new camera. If it does buy the damn thing and stop asking dumb questions. Its your acquaintance not ours you will see the camera not us so how the frig can we say its the right thing to do? If the seller turns up wearing a mask with a striped shirt and a bag over his shoulder marked swag then beware. If he comes by ship has got a peg leg and a parrot on his shoulder which screams Pieces of Eight continually then back out of the deal!
Good luck with your new purchase cos it sounds kosher to me bro so get it bought and take some snaps.

The only way the grommet spanner will work is if the shutter oil is used. Problem is that the oil can only work when the multi fluam drip applicator is placed in a left handed aspect

Thanks!

Highly unlikely. If someone were to go enough effort to cheat they would be selling it to someone without a personal connection. Odds are that that the user did not take to it or maybe even didn't enjoy photography enough to keep using it.

However there are other things that can go wrong with a digital camera simply from age and lack of use that have nothing to do with the shutter. I would ask for the right to return it after giving it a workout over the weekend.

Highly suspicious. If the previous owner was an employee of the DNC, it is VERY likely that this is a victim of Russian Hacking.

Now that you've explained it, it all makes perfect sense! Thanks! 😜

Hello,
I've been approached by an acquaintance who's friend has a really clean used Canon 7D body for sale for $400. I'm interested in buying it, mainly because I need one, but it supposedly has only 158 clicks on it (verified by EOSInfo).
The question I have is, can the recorded shutter actuation information be manipulated? I don't know the friend of my acquaintance and am hesitant given the camera is probably several years old.

Are you sure he didn't say it has 158k clicks on it. That's like 158,000 and not 158. No, the shutter count can't be rolled back. If it has this few clicks on it, then it would probably still be in the original box and none of the accessories will be unwrapped etc. You'll have to see for yourself. If you have a laptop computer you could install the shutter count app on it and check it yourself when you get it.

I sold a camera to a guy a couple of years ago but I had no way of checking the shutter count. The person lived in another state and was going to have a friend pay me in person and then take delivery on said camera. That was my 1D Mark IV. I included everything that came in the box including the box. At the last minute the person in the other state asked me what the shutter count was and I told him that I didn't know but the last time I took it to Canon for a clean and check it had around 66k on it. So he insisted that I guess how many it had so I guessed about 10k more or 76K. I told him it's a guess though. He got the camera about a week later and I guess he got that app and hooked it up to the cable and his computer said it had (I can't remember exactly but like 30k more than my guess) more than I told him and could I send him some of his money back. I said hell no, I only guessed and that he got a camera with a shutter that was rated for 300,000 clicks on the shutter for $1500. It's still an awesome deal.

When you have a camera that shoots 10fps, the shutter count can add up fast. Much faster than I guessed. If I were you, meet with the guy and ask him a few questions. His answers should provide you with info you need to make a decision on whether or not to buy it from him. If he used it once or twice and put it in the closet and never has taken it out since, then he may be telling you the truth. Just meet with the guy and you can clear it up fast.

I did a little research on this a couple of years ago while looking at a Nikon D2xs that had 558 shots on it. What I found out was that it could be done but some major parts would have to be changed. When I asked the owner why he bought such an advanced camera but didn't use it he simply stated "because my D40 is much lighter and easier to operate". He also had a boat that would run 80+ MPH and a 500 HP Corvette that he never drove because in his words "they scared the crap" out of him. Nothing like have more money than you know what to do with. I've enjoyed the D2xs immensely, the other two items mentioned are way out of my reach.

The Canon shutter counts roll over every time they hit 9,999.

On a camera that old, it is likely that the shutter count has rolled over several times, especially if there is an _ within the image number!

I've only had my Rebel T5 for just under 2 years, and I've rolled the shutter count over at least twice in that time!


The shutter count does not roll over! The file number rolls over.

And only Nikon D600's do that reliably!!!

I think the old Russian Zenit E required lard for a similar effect, although I expect that it can still be hacked without you knowing!

More seriously, the 7D shuttter count can be read by appropriate software, so it can be checked. I would still talk to the owner and see if the answers seem plausible.

I've had a shutter replaced by Nikon (D200), and they did not roll back the shutter actuation count. I've never heard of anyone being successful at doing this.
