In case you weren't aware this is a quick and easy way to find out your shutter count.

It may well work for some cameras, but there are a *lot* of cameras for which it would likely report erroneous information.

Canon has that EOS count program, but you need to pay to use it, its only a $1 i think. if anyone wants it i'll post the link later.

And AFAIK, EOS Count does not work on many non-1-series older models.

ETA: I know that Canon service centers can get at the information, but that's not much of a help to someone selling or buying.

On my Canon the info is contained in the EXIF data. Each time the counter rolls over (every 10k) it creates a new folder (starting with 100) on the card and the photo's "serial number" is incremented:
File: - L:\...\1307_Jul_Photos_2013\130711\IMG_6896.JPG


Make - Canon
Model - Canon PowerShot S3 IS

Image Number - 1076896

This was shutter actuation 76,896 ...

This is true with almost all older Canons... the problem is that this count may be reset, or set to an erroneous value, either on purpose, or accidentally. It's not really a reliable shutter count, although on many examples of a given camera it may well be accurate.

I tried it with my Pentax K10D a couple of weeks ago... 16,606 after 5 years. Seems about right.

Actually, I know this to be true -- the counter will re-set if the batteries fail while writing a file to the card (which also seemed to corrupt the card permanently :-( ). However, if you know how many frames were shot prior to the reset, you can subtract the "missing frames" from the final count and still have a fairly accurate count.

Yep. Another scenario that I personally ran into is insertion of a card that's been used in another camera, even one of a different brand (!). I had cross-species resetting going on between a Canon DSLR and a Nikon P&S!

Yes, this is a (the only?) good reason to reformat a card ...
