Has anyone tried the Precision Matte Focusing Screens for Canon EOS 5D-Mark II Camera? Any recommendations between the standard precision, super precision and precision with grid?

I'm curious to hear about this too. Here's a short video of how to install it: YouTube - Canon CPN - Changing the focus screen EOS 40D, 50D, 5D and 1D series

Well, the standard precision is just that -- standard, it's what comes in the camera. As I shoot almost exclusively on fast primes, I installed the Eg-S (super precision). It's better, but honestly didn't make as much of a difference as I was hoping. It's theoretically darker, so you won't want to install it if you're using autofocus lenses of f/4 or so. I'm glad I got it and it was worth it for me since you can discern sharp focus better, but it's not a night-and-day difference IMO.

And of course this has no bearing on video mode since the mirror is in lock-up.

I use the Super Precision (Eg-S) on my 5D2 and highly recommend it. It makes it much easier to see the plane of focus in the viewfinder. Of course, it's not much use for video.

As I'm sure you know, the standard viewfinder shows no difference between f/1.2 and f/3.5, so if you have any lenses faster than f/3.5 there is no way to see what's actually going on.

Many poeple find that anything slower than f/2.8 results in a viewfinder that is too dark; however, for me personally, I find it easy to use even with f/4 lenses, and I even use it at f/5.6 by letting my eyes adjust to the darkness. I prefer f/1.4 though, if possible. :)

Changing out the viewfinder screen for the first time is a lot easier (and less nerve-wracking) than the first time cleaning the sensor.
