The Sunpak DF4000U Universal TTL Flash is a high-performance, cost-effective speedlight designed to bring professional lighting capabilities to everyday photographers. Engineered with an intelligent universal hot shoe, this flash offers seamless TTL automation across multiple major camera systems. Boasting a formidable guide number of 190, complete bounce-and-swivel articulation, and an adjustable motorized zoom head, the DF4000U is a highly adaptable lighting solution perfect for weddings, events, portraiture, and indoor bounce photography.
Universal Cross-Brand TTL Automation
Intelligent Universal Hot Shoe: Designed to interface directly with major DSLR and mirrorless camera systems. The integrated multi-pin terminal offers automatic TTL exposure metering for Canon, Nikon, Sony, FUJIFILM, Panasonic, and Olympus camera bodies.
Plug-and-Play Exposure Accuracy: Eliminates the guesswork of manual flash calculations. The flash communicates natively with your camera’s exposure sensor to instantly deliver the exact amount of light required for perfectly balanced exposures, even in rapidly shifting environments.
High Output & Motorized Zoom Control
Powerful Guide Number: Delivers a robust guide number of 190 feet (at ISO 100), providing serious illumination power to light up distant subjects, balance deep shadows, or easily overpower harsh midday sun.
Motorized Auto-Zoom Head: The flash head automatically adjusts its internal reflector to match the focal length of your lens, ensuring optimal light distribution without wasting output. It can also be manually zoomed to control the spread of the beam.
Built-In Modification Tools: Features a pull-out wide-angle diffuser panel to soften and widen the beam for sweeping wide-angle shots, alongside a slide-out bounce card to create flattering catchlights in your subject’s eyes.
Dynamic Articulation & Creative Control
Full Bounce & Swivel Framing: The flexible flash head tilts up to 90 degrees vertically and swivels a full 270 degrees horizontally. This absolute freedom of movement allows you to bounce light off ceilings and walls, transforming harsh direct flash into soft, directional, and flattering studio-quality illumination.
Manual & Wireless Slave Flexibility: For photographers looking to explore off-camera lighting, the DF4000U incorporates manual power adjustments down to 1/128 power for absolute creative control, alongside built-in optical slave modes (S1 and S2) for wireless remote triggering.
Intuitive Interface & Reliable Hardware
Backlit LCD Control Panel: Outfitted with a high-contrast, easy-to-read rear LCD screen that cleanly displays current flash modes, manual power values, and zoom positions for lightning-fast adjustments in dark environments.
Standard AA Power Configuration: Runs on four widely available AA batteries (Alkaline or rechargeable NiMH), making it easy to keep your system powered up whether you are working in a local studio or traveling remotely.
