Nikon AF SB-23 TTL Speedlight
Introduced in 1988, Nikon SB-23 is a lovely, extraordinary compact TTL Speedlight unit. It is highly portable and despite its compactness and lightweight (weighs merely 140g), it has a great compatibility with many Nikon AF SLRs with its AF-assist illumination. It is also usable as an companion flash for Multi-Sensor Balanced Fill-Flash with the later Nikon AF cameras such as F5, F100, F90x, F85, PRONEA 600i or F70 etc. with any AF-Nikkor CPU lens*. With F4-series, F-801s, F-601, F50 or F-401x and a CPU lense **, it synchronizes well to be used as a dedicated Speedlight for Matrix Balanced Fill-Flash.

The SB-23 has been listed in Nikon product listing for quite a long time (even when the Nikon F5 was introduced, it was still available). The tiny flash is the most compact among all Nikon AF TTL speedlights prior to 3.2 oz Nikon ultra-compact Nikon AF-TTL SB-30 Speedlight that introduced in 2002/3. It is a very handy flash as secondary flash unit in a multiple flash setup and/or syncro-sunlight fill flash. Other than TTL auto, it can still be used in manual flash control.

Although the flash has not been equipped with many advanced features found in more sophisticated flash such as SB-24, SB-25 etc,. but this ultra-compact Nikon speedlight carries the advantage of being very economical and highly portable to be used as a small companion flash to fully supplement any Nikon AF SLR to explore TTL flash photography. The only apparent weakness you can pick on this flash is its rather weak guide number it offers but this is NOT essentially the main objective in its original intention to serve as a powerful TTL flash, so it is still all right if you can find its purpose in fill-flash in and around during location shooting.
