Hi, someone told me I should add this as bug report, so I'll try:
I bought a Yongnuo flash for my EOS 650d and noticed it does not fire with Liveview. Thank god there's MagicLantern I thought and so I tried ML. I had an older version from march this year on my SD card and I found the flash tweak, where you can use LV flash with non-Canon-flashes and XXXd-cams. What happened was this: I switched on live view, focused with half-pressed shutter. The live view vanished and I can press the shutter completely. The picture will be shot but no flash was firing. Afterwards nothing happened, the menu was frozen I couldn't do anything, just switching off the camera, everything else was blocked. After switching on it seemed half of the battery power had been gone in this operation. The picture was there but because of the missing flash fire too dark. Ok, I thought, maybe the build is too old and so I tried the nightly build from August 2nd. But: same problem, no flash, camera hangs.
Thank you! BTW, this is a marvellous firmware, I don't want to miss it anymore! Everytime I'm thinking about buying another cam I just compare the stuff the new camera can do and the stuff ML can do. ML is far up in the sky compared to all of the rest! You did a great job! Bad news for me: I have to stay with canon cams which is not always the cheap side of the world. But it's worth it! Canon should pump money in this project!
