The SIDANDE FK580 GN58 flash light speedlite for both DSLR and mirrorless cameras equipped with a standard hot shoe, it is ideal for photographers who use multiple systems and need a truly universal flash solution. Featuring a powerful guide number of GN58 (ISO 100, 105mm), this speedlight provides ample output for portrait, wedding, event, and studio-style photography. The strong flash power ensures clear, bright images even in challenging low-light environments or when bouncing light off ceilings and walls. Equipped with TTL automatic metering support (depending on camera model) and full manual control, the FK580 allows precise exposure adjustment for both beginners and advanced users. Easily switch between TTL for fast, accurate auto exposure and Manual mode for creative lighting control on location or in the studio. Support for high-speed sync (HSS) enables flash use at shutter speeds faster than the camera's standard sync speed (depending on camera compatibility). This is perfect for outdoor shooting, backlit portraits, and wide-aperture shots in bright daylight, helping you freeze motion and balance ambient light with flash. The adjustable zoom head covers a wide range of focal lengths, typically from wide-angle to telephoto (e.g., 24-105mm), automatically or manually matching the lens focal length to optimize light coverage. The swivel and tilt bounce head lets you bounce light off ceilings or walls for softer, more flattering illumination. Color: As Shown Material: ABS Package Contents: 1*DSLR Camera Flash Kit
