p.1 #1 · Canon 7D Shutter Count


I'm starting a new one because right now, you need to pull bits and pieces from several areas, and none of the instructions really hold your hand for someone who isn't savvy. If I've missed a step, or a step isn't detailed enough, please let me know.

1. Download Ubuntu here - http://www.ubuntu.com/download/ubuntu/download
- Select either 32-bit or 64-bit and click 'Start Download'.

2. Burn the disc (CD or DVD). There are a million ways to do this, I like Nero.
- Open Nero and select 'Recorder -> Burn Image'.
- A new window will open, in the top left corner it should say DVD or CD. If it says the opposite of what you want, click the drop down and change it.
- Navigate to and select the Ubuntu file, then select 'Burn'.

3. Leave the disc in your drive and restart your computer to boot in Ubuntu.
- I believe most systems will boot from CD automatically, see below for a generic 'how to set your pc to boot from cd'
- http://www.hiren.info/pages/bios-boot-cdrom

4. It might take a little bit, but an Ubuntu Try/Install window will pop up.
- Select 'Try Ubuntu', nothing will appear to be happening.
- Click the X in the upper left corner of the Try/Install window, it's okay if the little disc is still spinning (if a window pops up, select 'Cancel').
- After closing the window, you should see the basic desktop environment.

5. In the upper left corner, select 'Applications -> Accessories -> Terminal'.
- A command line window will open, type 'sudo apt-get update' and press enter. Take special care to type everything exactly, including spaces.
- Leave the Terminal window open for now.

6. In the upper left corner, select 'Applications -> Ubuntu Software Center'.
- The Software Center window will open, select 'Edit - > Software Sources'.
- A new window should open and default to the furthest left tab.
- Check the box that says 'Community-Maintained Open Source Software (universe)', then select 'Close'.
- It will sit there and update for several seconds (rotating green arrows and says 'In Progress' on the left side, just below 'History'), select the X in the top left corner of the window when it's done.

7. Heading back to the Terminal window.
- Type 'sudo apt-get install gphoto2' and press enter. Take special care to type everything exactly, including spaces.
- You will be asked to enter 'y/n' to continue. Type the letter 'y' on your keyboard and press enter.
- It may take a bit for this process to complete, wait until it returns to 'ubuntu@ubuntu:~$[]' before continuing to the next step.

8. Connect your camera with a USB cable and turn the camera on.
- From here on, don't let your camera fall asleep.
- If a window opens automatically, select 'Unmount' and skip Step 9.

9. In the top left corner, select 'Places -> Canon Digital Camera'.
- A new window will open, select 'File -> Unmount'.
- Close the window by selecting the X in the upper left corner.

10. Heading back to the Terminal window.
- Again, make sure your camera hasn't gone to sleep.
- Type 'gphoto2 --list-config' and then press enter. Take special care to type everything exactly, including spaces.
- Type 'gphoto2 --get-config /main/status/shuttercounter' and press enter.
- You should now see your shutter count displayed inside the Terminal window, it will be displayed as:
Label: Shutter Counter
Type: Text
Current: xxxxx (the xxxxx represents your shutter count)


Make sure you type everything correctly, I missed the space between 'config' and '/main' in Step 10 that caused me some grief.

Confirmed not working with a 1D3.

What if you don't have a CD. Are there a Ubuntu ISO for DVD ? I have not owned or purchased a blank CD in years.

It wont work with DVD.. at least its not with me. It stated the disc must be CD so apparently you need a different ISO for DVD and I don't think they have one.

Here - http://www.ubuntu.com/download/ubuntu/download

Step 2, it mentions using a DVD, I don't think you need a different iso.

When you say 'is stated', what exactly is 'it'? I think you just might need to use a different program to burn the disc.

You can also follow the link above and boot from USB.

Determine the shutter count exactly as stated above. Then take a fixed number of photographs. Then determine the shutter count again. Does the shutter count increment exactly by the number of photographs taken?

It was Nero that was not allowing it. I did the Windows 7 ISO burn and its working.

If you're using the Nero Burning ROM, after you select 'Recorder -> Burn Image', a new window will pop up. Make sure DVD is selected in the upper left corner. There are a million variations of Nero, I suppose it's possible you have a version that doesn't support burning image files to DVD.

I commend you on this clear step by step. Worked perfectly. I had my 7D listed as counts between 6,000 and 7,000. Actual count 7548.

Have you guys tried VMware player? It's free software and it can be used as a virtual machine within Windows to run any other operating system. Going this route would be much easier than using a CD.

Sounds cool but whats appealing to me about this method is you do not have to install anything.

Please advice

Saw this in a quick Google search...

http://ubuntuforums.org/showthread.php?t=1502629

Also note that it would be easy to miss whether or not it was updating.

I would probably start over at step 3 with the reboot, and try it all over again. If the same thing happens, you could try 'gphoto' instead of 'gphoto2' and see if that works.

Also make sure your computer is connected to the internet. I believe there is a little Mozilla Firefox icon near the top left, just to the right of Applications, Places, etc.

Nice write up. I might give this a go again, I tried it before on a Gentoo build laptop but the shutter count given was way too low. Thinking of selling the 7D though, so would be good to get an accurate figure if it's possible.
