Nikon AF SB-24 TTL Speedlight

Along with the extremely compact electronic TTL capable AF SB-23, SB-24 was also introduced in 1988 to supplement the AF-Nikon F801 (N8808 in US). The F-801 has a few very interesting feature in its design at the time of its introduction. Other than a high speed 3.3 fps built-in power drive, the AF Nikon is equipped with a fast 1/250 sec. flash sync speed which for the first time, offers Matrix-metered TTL fill-in flash and second curtain sync in a Nikon camera. For the first few months, the F-801 was seemed like a preview to showcase a possible how the next generation of the professional class Nikon SLR after the Nikon F3 will look like.

While the F-801 was debuted earlier (mid-1988), the subsequent pro-calibre Nikon F4 which introduced late that year in 1988 and immediately, all the essential technical features found in the amazing SB-24 can be fully realized immediately with the Nikon F4 - or in another words, Nikon F4 has a readily available high performance flash for photographers immediately when it was debuted.

This remarkable Nikon SB-24 TTL Speedlight offers TTL flash control on most TTL-capable Nikon bodies. It has many advanced features such as Matrix and Center-Weighted filled-in flash, TTL automatic flash control, Full power TTL manual flash control with multiple auto settings (five power levels), six apertures settings in automatic flash,direct and diffusion of power, repeating/stroboscopic flash capabilities, manual overriding, AF assist infrared beam for low or even total darkness shooting and a built-in variable zoom head for focal length control. The SB-24 can synchronize with up to four additional flashes. Head tilts from -7 degrees below horizontal up to 90 degrees above horizontal, and rotates -270 degrees to plus 180 degrees clockwise.

How various exposure modes in Nikon F4/F801(s) affect its functions

Similarly, with the Nikon F4 series and other capable Nikon bodies introduced at a much later stages, rear curtain sync and Multi-Sensor Balanced Fill-Flash with the later Nikon AF cameras such as Nikon 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. But the SB-24 does not support other popular features found in other later Nikon bodies introduced after F90(x), such as red eye reduction, FP high speed flash sync, 3D Matrix Multi-Sensor Balance-Fill flash, cordless slave remote function etc.

SB24itfavoritesC.JPG In order to accommodate all the sophisticated features, this features-rich Nikon AF Speedlight has to make use of a LCD display system helps to aid photographer to control all its various sophisticated functions. Incidentally, the SB-24 was also the first Nikon electronic Speedlight that carries a LCD display.

The indigo colour backlit LCD display provides 7 sections in relation to its functions:
1. Flash mode area (A/M/Strobe/TTL/Automatic exp. correction).
2. Manual exposure compensation indicator and bar graph.
3. Film speed/Strobe frequency indicator (in Hz).
4. Flash covering distance bar graph (in m and ft).

5. Zoom head indicator (in mm).
6. Aperture display.
7. Manual flash intensity compensation indicator.

* "CPU" lenses refer to those AF Nikkor, AF-I Nikkor, IX-Nikkor or Ai-P Nikkor lenses which feature a built-in microcomputer and CPU contacts. ** With F4-series, Manual Focus Ai-S or Ai Nikkor lenses are also usable.

The tiny light sensor that locates at the front of the flash provides non-TTL auto flash photography. The AF-Illuminator with IR-LED is for handling AF-assist focusing in low-light situations and it is automatically turned on by any AF Nikon camera. When using Continuous AF-Servo or Manual mode, the AF assist function will not be operative. But with certain capable Nikon SLRs, it will automatically activates. Depending on camera models, manual flash can be in TTL or full manual with adjustment to its light intensity as well. Flash Compensation> when used the SB-24 on 8808s/F90(x) and other Nikon bodies that follows + a SB-24 (or 25, SB-26 that follows) automatic flash compensation may occur. In high contrast situations (outdoors) no compensation is used. In low-contrast situations, compensation may be reduced. Manual flash compensation occurs when you make the head/shoulders symbol on the SB-24/25 flash. Dial in +1 to -3 compensation. This overrides any automatic compensation. Note: red-eyes reduction is not provided in the SB-24.

One of the main advantage presents in Nikon flash photographic system is forward and backward system compatibility. All Nikon AF Speedlights can be used on all Nikon SLRs individually and/or in combination. In a typical complex direct/off-camera multiple flash setup, all flash units can still retaining full metering and exposure control with virtually all Nikon AF SLRs. The connection depends on whether what you intend to achieve, they can be direct and/or via flash coupler(s), slave units as well as TTL sync cords.

The flash can be regarded as the first Nikon AF-TTL super-flash and has really leapfrogged Nikon into the catabult of being the pioneer in flash technologies At the time of its introduction, the many embedded functions in features that centered around TTL-Matrix fill flash and secondary supporting features such as full featured, all information LCD control panel, rear curtain sync, automatic zoom heads, flash exposure compensation, multi-sync terminals, auto/manual override control and the ability to accept a few external power sources has opened up many possibilities in flash photography never be able to experience before in a Nikon system. The F801 and the F4 series were the first batch of Nikon bodies that have truly benefited from the SB-24, the camera/flash combinations can interface each other in flash exposure control and a viewfinder signals system to alert and inform photographer of the status of the flash and/or exposure during shooting. The fill-flash is the main "essence" and selling point for the flash (and for the related Nikon camera as a whole) it is a function that balance the flash output with the ambient light for optimal, natural photography and everything is set automatically when a capable Nikon body/lense/flash is used in combination with various exposure modes set in the camera. However, the only issue is (apply to other flash unit), the SB-24 operates with each Nikon AF camera body differently (it is more simple when used with a MF Nikon), however, if your expectation is just only confined to autofocus only, that is more straight forward and easier but if , say if you are using an older Nikon AF SLR such as F401 or F601 etc. many of the advance features the flash offer may not be applicable and functional to work with those bodies, so be very alert of what can your camera offers first with this flash before commit to give yourself a threat. The SB-24 was eventually replaced with Nikon SB-25 TTL Speedlight in 1993 with some enhanced flash features to support some of the newer series of Nikon SLR cameras.

W A R N I N G: The New G-SERIES Nikkor lenses have no aperture ring on the lense, they cannot adjust aperture(s)when operating in manual exposure control even with certain earlier AF Nikon SLR camera models. Similarly, not ALL features provide in a modern AF-S series AF-Nikkor lenses can be utilized fully with a Nikon F4. Please refer to your local distributor for compatibility issue(s).
