Interesting read, thanks for posting.
I love the FLAO acronym, lots of those around here!
One thing the article didn't touch on was the issue I've discovered with my lens (or lens and camera combo):
http://www.ausphotography.net.au/for...sing-distances
"once done each of your lenses is locked in the camera’s memory and it will automatically compensate so that each lens is at a nearly perfect focusing plane whenever you mount it on the camera"
it is only nearly perfect for the distance that you calibrate the lens at.
With my 50mm f/1.4, the lens is perfectly focussed with a micro adjustment of +2 when used at a distance of 2.5.
But when i take a photo of something 10-15 meters away, the image is blurred at this setting, and i need to change the microadjustment to about +15!!!
Pretty confident that it's a lens issue rather than a lens/camera combo, but bit hard to explain.
