Lucky you! May I ask...how have you confirmed that no adjustment was needed?

My adjustments are primarily due to the camera. All my adjustments are around -10 (typically -8 to -12) for all my lenses.

I find most Zoom Lenses need adjustments... (Near and Far) I used a LensAlign Target with Ruler but found it to be long and subjective to my analysis, I've since invested in a great program called Reikan Focal which takes the guess work and time out of aligning my lenses.

Guessing your alignment is not the way to go... there's a huge difference in clarity and crispness with just +1 .. also when using this software or a LensAlign Target, Canon suggest 50x the focal distance I find 25-30x gives better results. A good rule would also be to test 50x if you shoot far from your subject and 25x if you shoot close to your subject.
