Fujifilm EF-42 Flash Unit for Finepix X100 / HS20EXR
The guide number of 24 to 42 changes automatically to the lens focal length while the flash will also zoom automatically between 24mm and 105mm (up to 20mm with the wide panel).
Allowing full manual control, the EV can be adjusted in 7 steps (-1.5, -1, -0.5, 0, +0.5, +1, +1.5) while the power ratio can be adjusted in 7 steps (FULL,1/2,1/4,1/8,1/16,1/32,1/64).
