As referred to by the Planet 5D Blog, this is software to automate the AF calibration feature on certain Canons: I haven't tried this because I don't OWN either of those cameras, but he's supposed to be developing it for 7D now also. It's currently in Beta and free, but he'll be selling it later.

| So is the idea that AF needs to vary with the lens? |

Newer Canon bodies incorporate a feature for AF micro-adjustment. This can help to compensate for minor offsets in AF due to the "match" between a specific lens and body. The software aims to automate the optimization of that adjustment. Cool idea, will have to see how it works in practice.

OK that's what I thought. I'm kind of embarrassed to admit that I haven't owned enough cameras in my lifetime to know if the Canon feature is as good as it gets. I do go manual sometimes because it doesn't seem to quite be working out for me. |

Let's be clear on this:
1. All camera bodies and camera lenses are produced to a "tolerance"; it's rare for anything to be exactly to specification.
2. Let's assume a range of tolerance of -3 to +3
3. This means in theory there can be a focal-plane discrepancy of 6 units between a given lens and a given camera.
4. Canon's micro-adjustments allow you to run tests to calibrate each lens to the specific body, and the body stores the information.
5. It's a tedious process.
6. This software supposedly helps automate that process.
