There has been a couple of representations of the FOV/AOV of various lenses - I have put together a complete table of the AOV that should cover all 4/3 lenses. This table differs from the graphical representations in so far that it calculates not only the Diagonal but horizontal and vertical angles as well.

The H and V are what we can easily relate to in terms of what you might see with a particular lens.

Please let me know if I missed either a start or end size of any current or past Zooms or any Primes, and I'll add them to my table and re-calculate them.

If it is of interest, I will get hold of the sensor dimensions for other sensor sizes and calculate them as well for comparison (just let me know).
