Give Your Pictures the Light They Deserve

Although most cameras come with an internal flash, they often lack the strength to deliver the light needed to properly capture a desired scene or object. That is why an external flash like Samsung’s SEF20A Flash is ideal. In its relatively small frame it deliver a high intensity of light, reaching up to 10m with certain camera settings, and ensures that your pictures are appropriately lit. It is also synchronized with the camera shutter so that the external flash times its release with the exposure period. Shooting like a professional has never been so easy.

Enjoy Perfect Lighting With Auto TTL Flash

Optimize your photographs with Auto TTL (through the lens) Flash. This allows you to take photographs with the correct amount of light hitting the film plane, achieved by controlling the exposure timing, and ensures that light saturation is not a problem. The biggest advantage of this feature is that it allows for elements such as aperture and shutter speeds to dictate the exposure and not the other way around

Brightness Control

With so many different external elements influencing the pictures you take, it is nice to have an adjust function to help control your shots. On the reverse side of the flash is a light control that lets you choose between how dark and bright you prefer to have your flash. This helps as lighting conditions alter, like between night and day, sunny and cloudy or simply shooting while being inside.
