Nissin is a traditional Japanese flash

The Nissin Di28 TTL Shoe Mount Flash for Canon Digital Cameras is an ultra compact, simple-to-use shoe mount flash that is fully compatible with Canons E-TTL flash system. It can be used with any digital Canon camera that supports E-TTL flash operation. Its standard design covers a 35mm lens, but it also includes a flip-down diffuser that adapts it to match a 16mm lens angle.
