The focal length 12mm (with 35mm conversion 24mm suitable) at the time the GN28 focal length 42mm (with 35mm camera conversion 85mm suitable) at the time new it is the large light intensity flash which was developed, in the one for digital single-lens reflex of the GN50. Illuminating angle adjusting to the lens, as it zooms automatically, can do also manual setting. In addition with the wide attachment the focal length 8mm (16mm suitable) it covers also wide illuminating angle with the 35mm camera. Also colorful luminous function such as curtain synchronizer after the red eye reduction slow synchronizer has. The GN is the when ISO100 suitable.
TTL automatic: After measuring the proper light intensity with pre-radiation, this it radiates. Automatic: It adjusts to the contraction of the lens, controls the luminous quantity in the light absorbent window of the FL-50. Manual: It radiates with the guide number which is set. FP-TTL automatic: It aligns even at high-speed shutter speed of 1/4000. FP- manual: The FP it radiates at the luminous quantity which it sets. The ±1/3EV mark light intensity revision of the ±3ev range is possible finely with step.
Red eye reduction radiation: The phenomenon where the eye is taken red by the radiation of the flash is made to lighten. Slow synchronizer: It radiates the flash with the slow shutter. Rear curtain synchronizer: The slow shutter is used, immediately before exposure ends, the flash radiates.
