Unfortunately I met another problem running the script.

As you might know, the 5D mk3, as well as some other new Canon cameras (1DX, 6D, 70D), offer the option for 2 AFMA adjustments (wide & tele). When I change the AFMA setting in Magic Lantern it adjusts both of these values within the Canon menu. I wanted to run the script and later change 1 value back manually.

For my prime lens (100mm 2.8 L, only 1 value in Canon menu) everything worked like a charm and the script identified a perfect match. For my Zooms (tested 24-105 4.0 L and 16-35 2.8 L before I gave up) the script did not work. For these 2 lenses the script ended up getting confirmation for all values from -100 to +100, leading to a calculated value of 0. When I manually adjusted the values for either wide or tele in the Canon menu (depending on which focal length I was testing) I ended up with the correct information and different values.

I checked all my lenses manually by now but still wanted to report the issue to you for future updates. I hope you are able to fix it and integrate the new wide / tele AFMA into ML.

Thanks a lot for the quick reply @ both ayshih & a1ex

a1ex's suggestion actually solved the problem. I usually just use my hardware buttons and top LCD display and have therefore disabled the "functional settings" for the INFO button, leaving it to show "camera settings" and "levels" only. After changing this setting the module runs without any problems.

As I am sure some other people will also run into this issue, would it be possible for the script to enable the "functional settings" on INFO before it runs and change back to the original settings later? Another option might be to change the error message since it really does not give any hint to solving the issue.

Either way, thanks a lot to both of you!

I seem to have a problem with using dottune on my 5D Mark III. I have been using Magic Lantern for a while on different cameras but just decided to try out this feature. I hope somebody can help me solve the issue.

I am using the newest nightly for 1.2.3 firmware (magiclantern-Nightly.2014Jul30.5D3123.zip). I have set up the camera on a tripod and focused on my target within liveview. When I start dottune from within ML the camera turns of liveview, toggles the info screen a couple times and then quits with the error message "press INFO and try again". I have tried the same procedure various times and also varied my distance from the target but keep getting the same result. I also tried to search for an explanation to the error message but came up empty.

Does anybody know how to fix this error or what I am doing wrong?
