What methods can be used to micro-adjust autofocus of a camera body to a particular lens?
I have a Canon 7D with a 50mm f/1.4 lens, and I think the auto-focus of the lens is off. How can I test and adjust this reliably?

I just got a new off-camera flash, and the instruction manual says:
Never fire the flash unit closer than 1 meter from infants.

We often see that a manufacturer's high-end (D)SLR models offer a "100% viewfinder," which shows the entire exposed frame, and allows precise composition with regard to objects near the edge of the frame.
