Manual Flash with Wide CompatibilityAs a manual flash, the TT600 works seamlessly with a variety of camera brands, including Canon, Nikon, Pentax, Olympus, and Panasonic (not Sony), thanks to its single pin hot shoe design. If you require TTL (through-the-lens) automatic flash metering, the Godox TT685 is recommended. Off-Camera High-Speed Sync & Optical TriggeringThe Godox TT600 can function as an off-camera flash, supporting High-Speed Sync (HSS) at shutter speeds up to 1/8000s when paired with Godox' X-Series Wireless Triggers. Additionally, it features an optical receiver, enabling it to fire in response to a flash from an on-camera unit. Robust and Adaptable Flash SystemWith a guide number of 60m at ISO 100 and 105mm, the TT600 delivers powerful illumination. Its output can be fine-tuned across 22 levels, from 1/1 full power to 1/128. The flash head rotates and tilts, allowing you to bounce light off surrounding surfaces for softer, more natural results. It also includes a built-in diffusion panel and an internal zoom mechanism, accommodating a focal length range equivalent to 14-200mm. Rear LCD Screen and Locking Hot ShoeThe Godox TT600 features a dot-matrix LCD screen, rear control dial, and function buttons for straightforward adjustments. It secures to your camera via a locking hot shoe mount and operates using four AA batteries (not included).
