Originally posted by D1N0 Is there anyway I can disable this, since it makes it harder to get critical focus right with a wide open aperture.
DoF preview in LV mode with change the aperture, and you can even use it in combination with magnification for focusing with the lens stopped down to the aperture that will be used for the actual exposure.

I don't know why LV does adjust the lens aperture in LV mode, I just assumed that the aperture is adjusted based in light and the more limited range of exposure times in video mode (live view is a kind of video mode).
