I guess all of my 50mm lenses will have problems with my 5D's mirror 
I went out to our park shooting landscape but when I had looked at the viewvfinder I just saw blackness, nothing more! I've checked the lens but it was at f:11 no lens related problem then I remembered the mirror issue subject and just turned a bit the lens to remove then heard the mirror down sound, oh no! Then again it happended and I just turned the focus ring down from infinity and again the mirror down sound. So I guess shaving process is a must for me.
I also have serious exposure problems with 5D but I guess this is not the proper place so I'll open a subject in technical part of the forum. The LCD on 5D really sucks, I need time to get use to it.
* Even 50mm is pretty wide for me so I guess I'll use my 85 and 135mm more than 50mm.

Interesting. I remember a photographer from dpreview forums, who used this combination without complication.

Portrait mode shot, right side was indeed the bottom side, I guess these black-outs are being caused by the mirror's touch and slow down.
full size version, 5D, ISO100, 50mm, was f.11 I guess, 1/60:

Shaving the lens sounds safer than shaving the mirror, but also shaving mirror is more practical as I've already 3 lenses having this problem. How do you shave the lens as I guess the touching part is the surrounding of the rear element.

Sure, I made the same conclusion. But I haven't yet shaved the 5D...

The same way Cogitech shaved the 58/1.3 Rokkor : http://www.cogitech.ca/Rokkor/
But I've used very grinding stone for knife instead of a file.
On SMC Tak 50/1.4 it doesn't have to be done on all the rear metal ring, only half part on top. Please don't forget to protect the rear lens element. I'm using Discofilm for that purpose.

Being not able to focus infinity with my Planar 50/1.8s is not nice as I was going to use one of them as a walk around lens so the mirror modification process is the rpute that I'll follow. And here is the ide:
