What To Know
- The guide number is a measure of a flash’s power, indicating the distance at which it can provide sufficient illumination for a subject at ISO 100.
- Additional features include a built-in diffuser on the SB800 for softening the light output, while the SB700 has a modeling lamp for previewing the lighting effect before capturing the image.
- For those on a tighter budget or who primarily use the flash as a slave unit, the SB700 is a capable and affordable option.

Guide Number and Flash Coverage
The guide number is a measure of a flash’s power, indicating the distance at which it can provide sufficient illumination for a subject at ISO 100. With a guide number of 122 ft (37 m), the SB800 offers more power than the SB700 (92 ft/28 m). This makes the SB800 a better choice for larger spaces or when working with subjects at greater distances.
Both flashes offer a flash coverage range of 24-120mm, which is suitable for most photography scenarios. The zoom range allows you to adjust the width of the flash beam to match the focal length of your lens, ensuring optimal illumination.
Zoom Range and Bounce Angle
The SB800 and SB700 feature auto and manual zoom options, enabling you to adjust the flash coverage to suit your needs. The SB800 has a slightly wider zoom range (14-120mm) compared to the SB700 (24-120mm).
The bounce angle, which refers to the ability to tilt the flash head upwards, is identical for both flashes (-7° to +90°). This allows you to bounce the flash off ceilings or walls to create softer, more flattering lighting.
Swivel Angle and Wireless Control
The swivel angle, indicating the flash head’s ability to rotate horizontally, is 180° for both the SB800 and SB700. This provides ample flexibility for positioning the flash to achieve the desired lighting effect.
In terms of wireless control, the SB800 offers both master and slave capabilities, allowing you to control multiple flashes remotely. The SB700, on the other hand, can only operate as a slave flash, requiring a master flash to trigger it wirelessly.
High-Speed Sync and Flash Duration
Both the SB800 and SB700 support high-speed sync (HSS), which enables you to use shutter speeds faster than the camera’s maximum flash sync speed. This allows you to freeze motion even in bright daylight conditions.
The flash duration, which refers to the length of time the flash emits light, is similar for both flashes (1/8000s – 1/1 s). This range provides flexibility for capturing both fast-moving subjects and low-light scenes.
Power Source and Other Features
The SB800 and SB700 both use 4 AA batteries as their power source. The SB800 has a slightly longer battery life than the SB700, but both flashes typically provide sufficient power for a full day of shooting.
Additional features include a built-in diffuser on the SB800 for softening the light output, while the SB700 has a modeling lamp for previewing the lighting effect before capturing the image.
Which Flash is Right for You?
The choice between the Nikon SB800 and SB700 ultimately depends on your specific needs and budget. If you require a powerful flash with master/slave wireless control, the SB800 is the clear choice. For those on a tighter budget or who primarily use the flash as a slave unit, the SB700 is a capable and affordable option.
Takeaways: Choosing the Perfect Nikon Flash
Whether you’re a seasoned professional or an aspiring photographer, understanding the differences between the Nikon SB800 and SB700 is crucial to making an informed decision. By carefully considering your needs and budget, you can choose the perfect flash to elevate your photography to new heights.
