Nikon SB-400 Speedlight External Flash
Ultra-Compact, Lightweight i-TTL Flash with Tilting Bounce Head
The Nikon SB-400 Speedlight is a remarkably compact, ultra-lightweight shoe-mount flash designed to provide intelligent i-TTL exposure control in a highly portable form factor. Engineered as an incredibly user-friendly external flash solution, the SB-400 offers a significant step up from standard built-in pop-up flashes by delivering greater power and advanced bounce functionality to eliminate harsh shadows and red-eye. While originally optimized to complement compact digital SLRs like the D40 and D60, its universal hot-shoe compatibility makes it an excellent pocket-sized companion for modern mirrorless creators, hobbyists, and professionals who require an efficient, grab-and-go lighting option.
Key Features & Engineering
Super-Compact & Pocketable Footprint: Designed specifically for shooters who want to minimize gear weight. Its ultra-portable profile slots easily into a pocket or small accessory pouch, making it perfect for travel, events, and casual street photography.
Intelligent i-TTL Exposure Control: Automatically communicates with compatible Nikon cameras to execute precise, balanced fill-flash calculations. It analyzes ambient scene light and subject distance to deliver natural, perfectly balanced exposures frame after frame.
Versatile 90° Bounce Capability: The flash head features a tactile tilting mechanism that articulates upward at 0°, 60°, 75°, and 90° angles. This allows photographers to bounce light off ceilings or nearby walls, producing a soft, diffused, and highly flattering portrait illumination.
Impressive Power & Reach: Boasts a versatile flash shooting distance range spanning from 2 feet (0.6 meters) up to 66 feet (20 meters), scaling dynamically depending on your camera’s active ISO parameters.
Manual Mode Adjustability: Offers standalone manual flash control when paired with select Nikon camera bodies, allowing users to fine-tune power ratios directly through the camera’s internal menu system.
Secure Shoe Locking Mechanism: Equipped with an integrated safety slide lock on the mounting foot, ensuring a rock-solid, wobble-free electronic connection to the camera’s hot shoe that protects against accidental detachment.
