6D Mark II Locked on Error 70

Davoud — Thu, 24 May 2018 00:55:03 GMT

After struggling for an hour or so with third-party camera-control software I ended up with an ERR 70 on my 6d Mk II.

The software that I was using is from a reputable developer; it is widely used by astrophotographers and I have been using it for years with various Canon DSLRs without a problem. This is my first attempt to use it with the 6D Mk II. Sometimes it worked, sometimes the software would fail to connect to the camera. It was in the course of troubleshooting this problem that I ended up with ERR 70.

Possible bugs in the interaction between Mac OS High Sierra and the camera could be at fault.

In any case, I ended up with ERR 70. Removing the battery for a couple of hours didn't help.Changing lenses didn't help. Reformatting the SD card didn't help. Other ideas most welcome.

Thanks,

David aka Davoud

Have you tried powering off, removing the SD Card and then repowering with no card installed?

Yes. Every conceivable combination of powering off/removing card/removing battery/changing lenses...

Use a new SD card if it won't work then try turn off the automatic sensor cleaning and see what happens.

I googled and found this link.

Another maybe useful info :

Quote : A Solution What I’m posting below is a method which gets the camera working again in most situations. It may need some steps done in a different order, or to be repeated etc, but playing with this set of operations gets it up and running again: First, put the camera in one of the C1/C2/C3 modes Adjust as many of the settings back to default as possible (custom functions, image mode etc). I’m not sure this step is necessary, but it’s worth a try. Power the camera off Remove the lens, switch to CA mode and power the camera up again You should see a menu rather than “Err 70″ It will be a cut-down menu as you’re in CA mode without a lens, but it’s there nevertheless. If you can get to “Clear Camera Settings” then do this. For me, I then just switched to Av mode and it all worked, and has been fine since

Thanks for taking time to reply. I fear that you missed the word Locked in the subject line. The camera does not power on, but only dsplays ERR 70 on the LCD Panel, so the notion of interacting with the menus is moot. The correct answer, according to Canon tech support just now, is to send the camera to a Canon repair facility.

Have you tried rotated the mode dial to C1 C2 etc before you switch on the camera ?

If it doesn't work, send it in for repair.

Remove battery, lens and memory card. Close battery and memory card doors.

Turn power switch to ON position, press shutter button and hold for 30 seconds to 1 minute. Turn power switch OFF.

This should clear internal memory and reset to factory conditions.

Refit battery, close door, turn power switch ON.

Thanks for taking time to reply. Sounded good—something I had not tried. Alas, it didn't help. Appreciate it anyway.

I had this same error. In my case this advice worked and the camera came back on but reported a problem with the card. I reformatted it and I'm back in business. Thanks Ray-uk!

I was able to get the camera displays turned back on and most functions work, BUT.......I cannot switch out of C1 or C2. As soon as I switch to any other mode, the camera goes dark, and nothing works except the flashing err 70 in the little display on the top right of the camera.

I have reformatted the card to no avail. If I switch to any other mode, I have tp remove and reinstall the battery before I can get the camera back on in C1 or C2.

Is there a solution to all of this. All I did was download a very popular astrophotography image capture program and plug the camera into my laptop. Apparently the 6D Mkii didn't like that for some reason. I have used that program for years with other Canon cameras with no problem.

Also, if I try to go back to factory settings............the camera will not do that in C1 or C2 modes. Catch 22!!

Now what?

Did you ever get the issue resolved? If so, how? I can only use my 6D Mkii in C1 or C2 mode. In any other mode the camera goes dark and nothing works..........except the blinking err 70 on the little display on the top right of the camera.

Thanks,

Barry

Easy. I sent the camera to Canon for repair. They repaired it under warranty and it has worked flawlessly ever since. That was more than 14 months ago, I believe.

From what's been said so far, this sounds like the sort of problem that might call for a firmware update. Have you made sure that you're using the latest firmware version? (I'm assuming that a firmware update can be done in C1 or C2 mode, though it's something I've never tried.)

This seems to have worked for me but time will tell. Only got the error 70 when turning the video on and sometimes it would within seconds and other times it maybe a minute or two before the error! I will test it on my gimbal, which is when the error appears within seconds. Thanks for this tip as you may have just saved me $400+ to get the camera repaired.

I know this topic is old, but I just encountered the same problem. And this is what I found. I had the Sigma 105mm EF Art lens mounted, and was trying to take some test pictures in live view(just received the camera). Finally out of frustration, I changed lenes to a canon lens. No more problem. I then changed to a different Sigma lens, and again no problem. With that information I did some more searches and this is what I found. https://www.sigmaphoto.com/article/canon-users-aug-2017 "When certain lenses are attached to these cameras and the “Lens aberration correction” function on these cameras is set to “Enable” for Live View shooting, an error would occur.
Please set the “Lens aberration correction” function of the cameras to “Disable” when using SIGMA’s interchangeable lenses for CANON.". I turned the aberation off(only first one in menu), and the problem was resolved. Not sure this is others problems, but this corrected the issue for me. I was having a panic attack because I just received the new camera and was in politically correct terms, having a bird.

Is the third-party control software something that changes/"enhances" the camera's firmware? If not installed carefully and correctly, you could have damaged it. Like a BIOS update on a computer going wrong. When that happens one ends up with a non-functioning brick.

If you don’t mind me asking how much did canon charge you to fix this issue? There is a camera for sale (same model) throwing this code so they are selling for pretty cheap off of mpb. Thanks
