Checking Actuations...

How can I check to see how many actuations my 20D has?

you cant. sorry.

As the saying goes "Only Canon Can!"

Note:
You can on the 1-series cameras using PS CS2 (or at least you can with the 1DsMkII) (Look in info/properties - advanced)
But you can't use that for the D60 or 10D so I presume not for other non-1 series.

There was a script you could run, but I have no clue where it is on the net.

Finally note that in both cases this presumes no one has hacked the camera to change the info. Canon supposedly has a secondary method which is not part of the accessable software.

There's a program called CanCount that can get you the information for the 1 series, but no similar program exists for other Canon DSLR's. AFAIK, and as it has been discussed here many times, only Canon can extract that info using a proprietary program/process.

i was gonna ask that same question - what about image file number from your memory card, does that count ?

The best thing to do is when you buy a new camera is to format the card BEFORE putting it in the camera. That way the camera HOPEFULLY starts out a 1. I say hopefully because you may have got a return or a demo unit. Then you have to be careful not to introduce another card with pictures already on it from a different camera or your numbering will be all messed up. However, if you do any tethered shooting those do not count and neither do shots taken without a card in the camera.

And then the first time you go on a trip and reset the numbering system to 0001 you have lost the count anyway. The numbering system is something that can be used for something useful, like keeping your photos from a trip in order.

I tried hard to keep my numbering consecutive on my 20D, but it went to Canon Service under warranty and they reset it

Have Fun,

The reason everyone says you can't is because it can be reset...but...if you know for sure that it hasn't, here is the way it's done...

each folder holds 99 images

101-0001 is the first photo in folder #1
101-0100 is the last photo in folder #1
the counter to the left of the - turns over when the right side of the - begins a new 100
102-0101 is the first photo in folder #2
102-0200 is the last photo in folder #2
103-0201 is the first photo in folder #3
109-1000 is the last photo in folder #9
110-1001 is the first photo in folder #10
each folder contains 100 photos/actuations
123-xxxx = 2,3xx photos
223-xxxx = 123 folders (remember the first column began at 1) = 12,3xx photos
929-xxxx = 829 folders = 82,9xxx photos/actuations

It can be confusing but there it is...

Close - 20D (and earlier models, excluding the 1D series) first frame will be 100-0001 in folder 100; even in the later models the first folder will be 100CANON, so the file (post-transfer via ZB) will be 100-0001.
Thereafter it's
100-0001 to 100-0100
101-0101 to 101-0200
102-0201 to 102-0300
123-2301 to 123-2400
199-9901 to 199-0000 (i believe this will roll over to all '0', but I'm not sure; it may stop at 199-9999)
200-0001 to 200-0100
until you reach:
9999-9901 to 999-9999 (can't roll over; you'll get an "Err CF" message)

Ahhhhh SSSOOOOOOOOOOOOooooooo​oooooo!

from my calcs ADD 100 clicks...

from Canon:
In the EOS 30D, the images you take are automatically assigned a file number from 0001 to 9999 and saved in a folder that can hold up to 9999
images. The folders will be automatically numbered from 100 to 999.

After folder 999 and images number 9999, no more images will be written to the card until it has been erased/formatted. After inserting a new card, the file numbering will restart at folder 100 and image number 0001.

Hope this helps...

I had the same thing happen, but since I like to keep track (as close as possible anyway) of shutter actuations I reset it back.

I forget the exact steps, but basically you have to switch from continuous numbering to reset and then insert a card with a copy of your last picture in the correct directory and switch back to continuous.

Numbering should start back up with the next image in sequence and your actuation count will only be off by however many Canon put on the camera.
