I just got my Lens Align Pro today, and decided to give it a whirl. I am BLOWN AWAY! This thing really rocks. It took me probably about 10-15 minutes to get set up, but once I did, the process is EASY! I checked my 100mm f/2.8 lens, and it was out. I dialed it in, and it looks 1000% better.
I want to point out one thing that is important - my 50D has the IR blocking filter removed, and at this time I am still waiting on my color correction filter (external IR blocking filter)... SO, this means that when I was testing focus using camera's internal focus it was probably thrown off by the IR wavelengths. I am not 100% certain of this, but it might explain why the lens was so far out. Either that, or I got another stellar copy of a Canon lens (which is getting old).
So... on to the good stuff!
Here is the test shot I took with Live View. Since Live View focuses using the data off of the sensor chip, it's going to be spot on.

(note, the images are inverted, and in B&W to make it easier to read)
Here is the first shot I took using the cameras focusing:

you can see right away how far off the focus is... sad... but interesting.
Here is the final shot after adjustment (+20 Back - this is as far as it will go!)

MUCH BETTER!!!! If I had to guess, I'd say the lens was front focusing by about 8" @ 15'. That's pathetic.
I can't wait to calibrate my other lenses. I am going to wait until the CC filter gets here, and then check them all. As much as I'd love to be affiliated with the folks at Lens Align, I am not... I'm just passing along some info on an amazing tool! It's a little expensive, but if you already sunk some serious cash in your glass, you might as well utilize it to it's fullest potential! I'll post more results for my other lenses when I get them done. Only bad thing is that now I know just how far off they are going to be on my 1D Mk II body. I sure hope they come out with a Mk IV soon, and include this amazing ability (micro focus adjustment).
One last shot...
This is a handheld shot of my laptop keyboard at f/2.8 focused on the front edge of the 'H' key. It looks awesome!
