Micro Focus Adjustments on Canon 1D Mark III and 5D Mark II

I’ve had a particularly bad experience with a Canon 50mm f/1.4 lens which has led me down the road of trying to understand the lens micro adjustment features on the new high-end Canon Cameras.

First a reference written December 2008 by

Here is another one discovered by Ron Matson on photo.net

And another which looks quite comprehensive:

As an aside, I chalk my experience up to getting a bad copy of the lens combined with my inexperience to realize such before my warranty had expired. If I had dealt with the problem immediately, I would be singing the praises of Canon’s customer service. Since I decided that I was the problem and not Canon and waited 3 years until I got a full frame camera and knew better, I am now stuck with the repair bill. Alas.
