Descripción del producto El Nikon SB-900 Speedlight, el avanzado buque insignia de las unidades de flash de Nikon, se basa en el SB-800 con mejoras innovadoras. Su cabezal de zoom automatizado ahora cubre lentes de 0.669 in a 7.874 in (en formato 1.378 in/FX) en solo 1,2 segundos. Puede elegir entre tres patrones de distribución de luz: Estándar, ponderado central y par. Se ajusta automáticamente para cámaras de formato DX o FX. El SB-900 puede funcionar de forma independiente o en grupos inalámbricos, ya sea como comandante o esclavo. Su sistema i-TTL admite iluminación inalámbrica avanzada, controlando hasta cuatro grupos de Speedlights con 3 grupos remotos i-TTL Speedlight. El control de relleno equilibrado i-TTL utiliza el sistema avanzado de comunicación de datos de Nikon, mejorando el funcionamiento inalámbrico y preflash del monitor para una mayor precisión, formando el núcleo del sistema de iluminación creativa. Yaxa The SB-900 i-TTL Speedlight leads the Nikon Creative Lighting System by delivering the portability, power, and versatility to support any photographer's creative lighting imagination. The SB-900 works as a wireless standalone flash, or you can use it as a commander or wireless remote light source. In commander mode, the SB-900 controls up to three remote Speedlight groups and an unlimited number of compatible Speedlights, with four wireless channel options helping you manage wireless conflicts in multiple photographer environments. The flash also offers streamlined controls and menus, including a rotary select dial that sets key flash functions quickly, along with a prominent master and remote control switch to simplify wireless operation. Photographers working on zoom photos will appreciate the SB-900's expanded auto power zoom coverage, which ranges from 17 to 200mm in the FX format to 12 to 200mm in the DX format. Photographers also have the choice of three light distribution patterns: standard (for general illumination), center-weighted (for portraits), and even (for groups or interiors). Finally, the SB-900 automatically identifies mounted color gel filters and adjusts the camera's auto white balance setting (available with select Nikon digital SLR cameras). Other details include automatic FX/DX format identification; user-friendly firmware updating; flash tube overheat protection; and a drip-proof mounting foot cover.
