And just remember it's only there to set up the shake reduction system. If you switch that off you'r not asked for the focal length when you turn the camera on.

Av is formally defined as 2 x log(base2) of the aperture. So 2 x ln(13)/ln(2) is ~7.40.
Why log(base2)? Because each whole number increase represents a doubling, i.e. one stop.
Why multiply by 2? Because the amount of light let in by a given f-stop is proportional to the aperture's area rather than its diameter, so the aperture squared is the key variable.
A fuller explanation is here:

Good luck with the job hunting Andrew. I was lucky only had one qualification to remember, although I did a lot of job related courses which were really a bit of a holiday.
