I use all modes of live view and constantly change them since I try to learn taking videos as well and I'll record some videos from locations as well. For some lenses I use exposure simulation (ZE lenses) and for some I use the still mode without exposure simulation (the ones adapted with EMF programmable ships) or when I change lenses in fast phase I have ended up shooting ZE also without exposure simulation. If in situation in which camera automatically uses smaller aperture to show live view picture but I would use alternative lens with manual aperture the live view picture would "clip" the highlights, the sensor cannot handle too much light and still show good picture, at some point pixels get overstatured when too many photons hit them.
I checked manual (naturally I have read it before but since you said it's explained there I was thinking I did miss something) and it doesn't even mention that in bright light aperture is closed down to be able to show live view picture properly. So could you please clarify which page/chapter of manual you are referring to? I did re-read 107-126 (whole live view chapter), specially paying attention to 109 (modes), 125-126 (the gray warning/notes boxes).
There are following menu options affecting how live view is shown. I'm not sure what you refer by having mode in which lens aperture is not adjusted to protect sensor from too much light, please advice what menu combination to use:
"LV func. setting":
- Disable
- Stills only
- Stills+movie
Then next menu is called "Screen settings":
- Stills display
- Exposure simulation
- Movie display
I don't typically watch to the lens when I'm shooting since I'm on other side of the camera, but I find this happening when I'm in 10x and press DOF button to mitigate focus shift when focusing and then I see that nothing happens when I press DOF button. First I did think the DOF button doesn't work but then I once checked and aperture was closed to f/2.8-4 (hard to evaluate by watching the lens from front) even I had f/2 selected from camera. This only happens in bright light so in Finland it's problem only in few days a year 
Instead of live view settings it seems that using M and Av (I did not try other modes since I never use them) seem to have difference in way how aperture behaves, again no word on manual about this either. I'll need to study this more to figure out is there even possibility to automatically use the shooting aperture for live view focusing as well, which would mitigate whole focus shift for live view users automatically....Show more →
Sorry I didn't reply sooner, after posting my image, I clicked the quote button and the internet shut down on me, so I figured I might as well go to bed. It may not be in a manual but it may be downloadable pdf on canons site, after they updated the firmware they added instructions.
Maybe we're having a communication break down, so first I will describe the way my camera acts on certain settings, then I will tell you what settings I use.
M mode: My liveview shows me EXACTLY what I'm going to be shooting. If I up the shutter it brings in less light, if I up the f/stop it brings in less light and the lens closes up. I can similarly open it right up and point it at the sun and my screen will go white and stay white. (I don't do that, though I could). Shutter and Fstop controls what I see as it would if I took the photo.
THEN I wrote about the Av and Tv settings, and I know what I wrote to be true because the other day I did a shoot where I needed Av mode liveview on a photoshoot of a store. I was looking at where the reflections were coming from etc.. Then 2 days ago I updated my firmware, and after reading your post I grabbed my camera and started playing with the settings so I could help you, and my camera is acting erratically on the Tv and Av settings mode... I'm a bit worried now that something's either wrong with my memory, or canon changed something that I'm not happy with.
ANYWAY, regardless of that, set your camera like this and you should be fine no matter what lens you are using.
Live View/Movie func. set.
-LV func. setting
-Stills + movie
-Movie display
Then set your camera to M mode, and you should be all set. You control the aperture and shutter independently of the camera, and the live view shows you exactly what you need.
So basically then if you have a lens with focus shift, when it's set to 2.8 it'll automatically close up the aperture so you can then focus using the aperture natively. AND if you were lazy, you could just put your ISO to Auto and you wouldn't have to really worry about exposure. Just set your shutterspeed to something manageable for hand holding, and your set.
Hope this helps,
Adam
P.S. I think I'm going to start a new post in the canon forum now, as I'm scratching my head as to my thoughts on my camera.

and congratulations on your new lens!
