The Metz Mecablitz 15 MS-1 Macro Ringlight Digital Flash is an advanced macro ringlight flash that provides full wireless TTL control with virtually any SLR camera system. Brands supported currently are Canon, Nikon, Olympus/Panasonic, Pentax/Samsung and Sony Alpha. The MS-1 is a highly customizable macro flash. Each of the two separate flash bulbs inside the ringlight are individually controllable, and each reflector can be swivelled with a range of 0-20°. The Ratio Control feature allows for separate light distribution settings for the left and right sides of the flash, while the variable power setting allows for 6 levels of scaled-back output. In addition, the bouncer disc provides further softening of the light output. The dedicated wireless TTL control function and the built-in power supply does away with the need for cumbersome flash cables.
