The Nissin Di600 is a successor to the well-established Nissin Di622 Mark II flash gun. The new model has a similar feature set to its predecessor, but at a better price point. Powered by four AA batteries, the flash has a zooming tilt-swivel head, and the guide number is 44 in metres (at ISO100/21°) at the 105mm setting. A 16mm wide-angle diffuser is built in together with a fill-in reflector. The new gun is available now in Canon and Nikon fit, with Sony fit available in November. The suggested retail price is £145.50.
