i have a 1ds2 and would like to know the shutter count. i use a macbook pro so cancount will not work.

Pm sent your way Grant.

This is all you need and there is a mac version:

http://www.sno.phy.queensu.ca/~phil/exiftool/

It is freeware and tells you way more than the shutter count. It'l give you everything in the exif. There is a windows version and a gui interface to run it for windows here:

thanks to both lance and steve.

question: i sent steve a pic and cancount reads 12741

exif viewer has two actuation # locations:
1. Actuation Counter: 12741
2. Camera Actuations: 209349

i am to assume Actuation Counter is accurate as it coincides with cancount?

I've never seen that second field but then I have a 1Ds which has a "ShutterCount" field in the Exif. I'm sure the Mark II has different fields in the Exif than the earlier models.

From my understanding actually I would be inclined the believe the 209349 number. Each time the actuation counter rolls past 65535, it leaves a marker behind, and resets to 0. So the final actuations would be determined by 65536 times # of markers + actuations counter (you'll see later, why 65536 is used).

I've seen this in exif viewer my 1ds2 and 1d2 before after they've rolled past 65535- 1dcount matched the higher number perfectly, and my estimates as well coincided with the second number.

In this case the 65535 rolled over 3 times, plus 12741 is 209346. Why is it 3 less than 209349? Well each time it rolled over from 65535 to 0, that actuation should count, so technically we should be multiplying by 65536.

thanks orange.

therefore, when the shutter rolls past 65535 it sets back to zero so cancount will/should never give a shutter count higher than 65535. is this true of cancount?

I've gotten correct numbers from 1dcount and exit viewer- never used cancount- but that seems like it's not reading the rollover tag that the camera uses- what do you think is the correct count?
You should know since those numbers differ by almost an entire shutter life...
