Lightweight and ideal for travel, the Vivitar 728AF flash is dedicated to Canon EOS AF SLR cameras. It provides complete autoexposure flash operation, while the Auto Thyristor circuitry allows for a faster recycling time as well as more flashes per set of batteries. Because bounce light is very soft and resembles typical room lighting, this flash gives your images a more natural look than conventional flash photos. The Vivitar 728AF creates a wide zone of soft, even lighting, so your subjects are less likely to be too light or too dark. It also reduces the red-eye effect that most flashes cause.
1 Great - if you know your limitations
This is a very nice compact flash that is great for travel. I've used one on a Canon EOS Elan body and had very good results. However, you must keep in mind its limitations when considering it. If you're looking for a flash do to weddings or low light events then this is not your flash. With a guide # of 92 it is best used for outdoor fill flash or when you can get close to your subject. Based on the price I think it's a great little flash if you keep in mind what it was intended for.
2 Great flash, but.......
it will easily break where it slides on to attach to the camera. There is no way to reattach the flash to the camera once that little bit of plastic has broken. Needs new design where the flash attaches to the camera.
