Depending on whether the Fresnel Small is used with a flat fronted och protruded flash head. Below the max and min beam angles for each are stated:

Protruding Head				Flatfront Head
Open		Closed		Open		Closed
Beam	Field	Beam	Field	Beam	Field	Beam	Field
16.5°	31°	7.5°	13.5°	21°	34°	7.5°	13.5°

Beam angle = 50% intensity

Field angle = 10% intensity
