Hi,

Can someone help me find the shutter count in my 1D mark II

I am planning to sell the same and want the shutter count for the same. I am not sure if i can ask for this kind of help in this forum. If i am wrong, please mods, delete the post.

My intention is to get some help to find the shutter count and nothing else

It looks like Canon might be storing it in an EXIF Tag (0093) from what I could find from a search of various boards. Use an EXIF reader like the free Opanda IExif and look for tag 0093.

You'll see values that look something like this in the line (with the 20000 value in this example the one you'll probably find that's close to your actual activation count).

18,0,20000,0,0,0,65535,65535,0

The values for this tag are 16-bit, and are displayed in decimal in most EXIF readers. The first value is ignored.

The second value is the most-significant word (MSW) and the third value is the least-significant word (LSW) of the actuation count. The total count is (MSW * 65536) + LSW

In the example above, that would make the shutter count 20000:

(0 * 65536) + 20000 = 20000.

In most cases, the third value is going to be the shutter count from what I can see others reporting, but I have no way to verify the accuracy of that info.

Uhm, my 0093 reads:

32,39623,208,0,0,0,65535,65535,0,0,0,0,0,0,0,0

That means I have (39623 * 65536) + 208 = 2,596,733,136 Actuations?

I guess they really understated their shutter life on the 20d?

That's a pretty good shutter. lol

The posts I found were related to the 1D series models, not the 20D. ;-)

the reading is specific to 1D series and probably not for the xxD series.

Here's an article about a program that can read the EXIF and give you a shutter count from 1D series images (it's probably just looking at that EXIF tag to find it):
