Nikon TTL Macro Speedlight SB-29s

February 21, 2002

Nikon Corporation is pleased to announce the introduction of the Nikon TTL Macro Speedlight SB-29s.

Although it inherits the functions of the Nikon SB-29 model that it succeeds, the SB-29s also offers M1/32 flash output to help assure correct exposure with current and future generations of digital cameras featuring high sensitivity.

The Nikon SB-29s marks a significant advance for the Nikon Speedlight lineup, offering photographers enhanced flash shooting flexibility for a wide range of applications.
