Can anyone recommend a site with instructions on setting MFA that has worked well?

Sure. Start with this one:


Also, make sure you have a very good, high contrast target and good lighting. This is a pretty decent one. Print it out at with as high a quality as you can:


Do try to use Canon's 50x the tested focal length recommendation, though with a very long lens that might be difficult, and I've had decent luck testing closer in than that. Also, suggest you test a zoom at 2-3 different FL's. If you see major inconsistency in whatever adjustment is required, you should probably consider sending the lens to Canon for adjustment.

Good luck.
