We should just have the option anyway. If I'm away and i have limited card space I might want to shoot 2.7k, plus it is much quicker to edit/encode. We pay more for our pros so should get all features. I'm kind of annoyed that they only are giving it to advance owners. Hopefully they just didn't list it but it will be there as an option.Doesn't look like it. Are there advantages, other than file size, of 2.7k over 4k?
