SB-102 and SB-103


The SB-102 and SB-103 free divers from complicated, time-consuming exposure calculation when an interesting subject swims by.

Synchro-sunlight shooting is also possible underwater with a feature that allows you to compensate and balance the lighting in the picture. In Auto or Manual settings faster than 1/90 sec, the Nikonos -V’s shutter is automatically used at 1/90 sec when the SB-102 or SB-103 is connected. However, the shutter speed that would match the aperture setting if you were not using the flash will still blink. Thus, you can tell at a glance the difference in shutter speeds to be compensated for in synchro-sunlight photography, and can thus adjust the aperture for the best effect.

Other features of the SB-102 and SB-103 include TTL multi-flash capability and manual flash output control. In addition, the SB-102 features a non-TTL automatic flash control, a light-sensitive firing mechanism for wireless slave capability and a target-light for close-up or dimly lit situations. Target lighting allows your to zero in on tiny subject up close. It also lets you aim the flash underwater or in the dark. A variety of other accessories is available to further increase the versatility of the SB-102 and SB-103.
