Nikon SB-700 Speedlight

Features advanced multi-functional flash technology

As part of Nikon’s popular Creative Lighting System, the SB-700 includes support for Nikon’s advanced wireless TTL operation and can function as a wireless Commander with control over two separate groups of Speedlights, or as a Remote Speedlight when controlled by the SB-900 Speedlight or the built-in Speedlight set to Commander Mode in most Nikon D-SLR’s. The SB-700 also incorporates a high-speed recycling time of approximately 2.5 seconds for full power with NiMH batteries, and approximately 3.0 seconds with AA Alkaline batteries. The Nikon SB-700 also features a new Quick Wireless Mode with A:B (light ratios) for quick setting of multiple flash units. This makes it easy and quick to control two remote flash units in i-TTL mode.

Additionally, the SB-700 also features enhanced Thermal Cut-Out detection that automatically detects heat build-up due to rapid flash firing. By increasing the recycling time if the temperature of the flash head rises above a certain threshold, the SB-700 protects the flash from damage due to overheating.

For improved durability, heat-resistance and ease-of-use, the SB-700 uses new hard plastic-type color filters for fluorescent or incandescent color temperature balancing. When using the supplied filters, the flash automatically recognizes which filter is being used and adjusts white balance accordingly on select Nikon D-SLR cameras. Additionally, the SB-700’s AF-assist illuminator is compatible with the complete line of AF systems used in Nikon D-SLR cameras*.

Similar to the Nikon SB-900 Speedlight, three illumination patterns (standard, center-weighted and even) can be selected in SB-700 to match each shooting situation. When “even” is selected, the light from the flash will cover a subject from center to edges without light falloff. This pattern is suitable for shooting group photographs indoors. The “standard” pattern will cover all conventional, standard flash coverage. The center-weighted pattern provides larger guide numbers than other light distribution types at the same focal lengths. This illumination pattern is suitable for subjects such as portraits, in which the light falloff at the image edges can be ignored.

Like the Nikon SB-900, when the SB-700 is mounted on a camera compatible with user firmware updates, the SB-700 firmware can be updated using the same procedure as with a Nikon D-SLR camera.

Available accessories
The SB-700 uses four AA type Alkaline, Lithium or rechargeable NiMH batteries. To enhance the weatherproof ability of Nikon D-SLRs, optional water guards will be available for select cameras to protect the connection between the flash and camera, allowing users to utilize the flash when weather conditions are less than ideal. The SJ-4 Color Filter set provides a Warming, Red, Yellow or Blue filter for adding color to the background, foreground or just to accent the scene.
