Hi to all,
I am playing with my 380ex and was checking out guide table for my 380ex, but I don't quite understand some of the nos...
Guide No.Table 380ex
The guide no. table is right after the specifications table.
The part I don't understand are those no. beside the various shutter speeds.
Eg. at shutter speed 1/180 the nos. are 11.2, 12.3, 15, 16.6, 17.6, 20.3
What are these nos.? Aperture setting?
Any advise is greatly appreciated. Thanks!
