UNIVERSAL DIFFUSER COMPATIBLE WITH ALL SHOE MOUNT FLASHES OF ALL BRANDS (EXCEPT ROUND-HEAD FLASHES) THIS MODEL CAN BE ATTACHED IN SECONDS DIRECTLY TO ANY EXTERNAL FLASH. THANKS TO ITS LARGE SURFACE, IT ALLOWS LIGHT TO BE DIFFUSED MUCH MORE UNIFORMLY COMPARED TO THE TRADITIONAL DIFFUSER SUPPLIED WITH THE FLASH. VERY EASY TO ASSEMBLE AND DISASSEMBLE, EQUIPPED WITH 2 SPECIAL STRAPS (1 VELCRO AND 1 ELASTIC) THAT ALLOW YOU TO ADJUST AND SECURE THE DIFFUSER TO THE FLASH AS YOU WISH. DIFFUSER SIZE: 12.5X10.5 CM ESSENTIAL FOR SOFTENING THE LIGHT EMITTED BY THE FLASH AND REDUCING HARSH SHADOWS; THE RED-EYE EFFECT; THE VIGNETTING EFFECT BY SIGNIFICANTLY INCREASING THE DIFFUSION ANGLE OF THE EMITTED LIGHT (SEE PHOTO BELOW FOR THE DIFFERENCE WITH AND WITHOUT DIFFUSER) MADE OF HIGH QUALITY AND RESISTANT PLASTIC MATERIAL THAT PREVENTS ACCIDENTAL BREAKAGE OR BREAKAGE CAUSED BY PROLONGED USE, EVEN IF EXPOSED TO THE ELEMENTS OR SUNLIGHT. N.B. THE LISTING ONLY INCLUDES THE DIFFUSER! The flash shown in the photographs is not included!
