Hi Robert, thanks for your message.
Looking up the spec. sheet, the apparent field of view (afov) for each incremental zoom 'stop' is:
8mm yields 68deg
12mm is 63deg
16mm, 58deg
20mm, 53deg; &
24mm, 48 degs.
I seldom used the 24mm setting, it is a little narrow for my liking - all others are fine (for me, anyway).
Regards, Dean
