The diffuser is used to create exposures of even density over the entire surface of film.Use the diffuser by placing it flush against the front of the lens and exposing through it.Try use and see the difference.The flash with our diffuser installed and tilted at 45 degrees gives a nice soft wrap around of light with a soft shadow behind the subject.It disperses the light over a wider area for a softer, more balanced and natural effect than you didn& 39;t use before.This fits cleanly over the head of your existing flash, no need for cumbersome attachments, hooks.The light that passes through the diffuser and on to the film will create an even density across the surface of the film.Flash straight on if without our diffuser causes the light to go forward only and creates a harsh shadow behind the subject.Suitable for:For Canon: 580EXII, 580EX, 550Ex, 540EZ, 430EZ, 420EZ, 430EX, 420EX, 380EX, 520EX, 300TLFor Nikon: SB24, SB25, SB26, SB28, SB28DX, SB50DX, SB80DX, SB800, SB600, SB900For Minolta: 5600HS, 5600HS(D), 3600HS(D), 3500xi, 5400HS, 5400xi, 5200iFor Sigma: Sigma 500 SeriesFor Sigma EF-500DG, EF-500DG SuperFor Sigma EF-500 DG II, EF-500 Super IIFor Contax: TLA 280, TLA 360For Metz: 40-MZ-2, 44 AF-4, 40 AF-4M, 54 MZ-3, 44 MZ-2, 54 AF-1C, 54 AF 1N,44 AF-4C, 44 AF 4N, 54For AF-4i, 54 MZ-4, 40 MZ-3i, 54 MZ 3, 54 MZ 4, 36AFFor Metz: 45 CT-1, 45 CT-3, 45 CT-4, 45 CT-5, 45 CL-1, 45 CL-3, 45 CL-3For Sony: HVL-F32x, HVL-F1000, F36AM, F56AMFor Olympus: FL40,FL50, G40, FL36For Soligor TIF 380, DG-420ZFor Sunpak: 2000DZ, 266D, 355AF, MZ440AF, PZ5000AFFor Vivitar: 2500, 273, 3500, 5200, 550 FD, 728AF, 836, 840AF, 850AF, DF200For Achiever: 260AF, 260T, 630, 828, 828TW, TZ250For Cobra: 480AF, Auto280For Nissin: 360TW, 360TXP, PZ400-c-n-mFor Promaster: FT-1700, FTD5700, FTD6500, FTD7000MFor Pheonix: 80DZA, 82ZBDA, D79-BZS, ZB1-92NFor Pentax: 330FTZ, AF500FTZItem Name: Flash DiffuserMaterial: ClothFeatures: Easy Installation, Photography Accessory, UniversalDimension: 6.5cm x 4cm x 5.5cm/2.56" x 1.57" x 2.17" (Approx.)Notes:Due to the light and screen setting difference, the item& 39;s color may be slightly different from the pictures.Please allow slight dimension difference due to different manual measurement.Package Includes:1 x Flash Diffuser(Other accessories are not included.)
