But honestly they all look work around and not really practical.

#Cg03 white balance lock manual
PS - Sure I know all kind of tricks of waring a grey wrist band or using grey card or making a chart to see what time I should use what colot temparature or manually trying to match the AWB with the manual WB. Or is there already such options available and I am just not aware of it! But it is completely different ball game for video where a RAW is not really an option for common people due to the unmanagable size of image files! This is specially useful for video as for still you can push the WB as much as possible as normally if you are doing serious photography you would capture RAW images anyway. And this is not that quick either and doesn't always work properly! A bit of hit and miss! But it is dengerous as if I forget to change it it is kind of a big problem. So if Canon can offer an option to lock the AWB during video recording it will be an amazing tool! For now I started using a work around to copy the AWB to the custom WB and use that for the video. It is almost impossible to get such level of accuracy with manual set of white balance without always taking custom white balance with agrey card and as I said before that is absolutely not practical for outdoor shooting in most of the cases. And it seems the AWB doesn't only manage the color temparature, but also the tint.

I can see that Canon recently does an amazing job of setting the white balance in Auto white balance mode. It is not always practical to carry a grey card and set the custom white balance. I find it extreamly inconvinient if you are making outdoor movies. For many years I have been using manual white balance for video.
