Compatible With: Canon 50D/40D/30D/20D/10D/550D/500D/450D/400D/350D/300D Nikon D700/D300S/D90/D80/D70S/D70/D60/D50/D40X/D5000/D3000 Pentax K-7/K20D/K10D/K200D/K100D Olympus E-620/E-520/E-510/E-500/E-450/E-420/E-410 Panasonic G10/G1/G2 * 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. This fits cleanly over the head of your existing flash, no need for cumbersome attachments, hooks. Try us and see the difference. * 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 * It disperses the light over a wider area for a softer, more balanced and natural effect than you didn"t use before.
