Next-Generation 2.4 GHz Speedlight Powerhouse Innovative TCM Exposure Conversion & Expanded Pivot Matrix
The Godox Thinklite TT685O II is an advanced, high-output shoe-mount speedlight custom-tailored to fully support Olympus and Panasonic’s native automatic TTL exposure systems. Boasting an integrated 2.4 GHz X wireless radio transceiver matrix, this updated second-generation flash seamlessly transitions between acting as a wireless master transmitter or a remote slave receiver. With an impressive guide number of 197 feet at ISO 100 and an expansive auto-zooming head spanning 20-200mm, it delivers the raw illumination performance required for demanding portrait sessions, fast-paced event reporting, and multi-strobe studio configurations.
Engineered with contemporary workflow breakthroughs, the TT685O II introduces Godox’s unique TCM (TTL Converted to Manual) function, allowing creators to instantly convert an automatic TTL exposure reading into fixed manual power values. Combined with an upgraded bounce head that tilts from -7° to 120° and rotates a full 330°, this versatile lighting tool offers unprecedented geometric flexibility and lightning-fast setup times.
This speedlight is in full operational condition. The package comes well-equipped for storage and location work, including the original protective soft storage case and a slide-on desktop mini-stand.
Key Features & Advanced Radio Capabilities
Olympus & Panasonic TTL Architecture: Communicates natively with Olympus and Panasonic camera systems to unlock professional automated lighting features, including high-speed sync (HSS) up to 1/8000 second, flash exposure compensation, and first/second curtain synchronization.
Integrated 2.4 GHz X Radio Transceiver: Operates flawlessly over an expansive 328-foot (100-meter) radio radius across 32 channels and 4 independent groups. Functions as a commanding transmitter unit for Godox V1, AD200Pro, and AD300Pro strobes, or as a receiver paired with X1, X2, or XPro commanders.
Innovative TCM (TTL-to-Manual) Switch: Features a dedicated shortcut that instantly converts automated TTL exposure calculations into exact manual power assignments. This locks in your illumination balance, prevents sensor metering fluctuations, and creates a baseline for manual lighting arrays.
High-Power Output & Zoom Control: Delivers a potent guide number of 197 feet (60 meters) at ISO 100. The motorized flash zoom head self-adjusts between 20-200mm to match your active lens focal length, backed by a manual power range scaling from 1/1 down to 1/128 in precise 1/3 EV steps.
Expanded Geometric Bounce Architecture: The re-engineered articulation head tilts from -7° to 120° and pans a total of 330°, allowing for fine-tuned directional light placement when bouncing flash off low ceilings or studio reflectors.
Quick-Release Lever Hot Shoe Lock: Outfitted with an efficient mechanical quick-release slide lock on the foot plate, replacing tedious screw-down locking collars for rapid mounting and breakdown during critical shoot transitions.
UI Ergonomics & Electrical Connectivity
High-Contrast Rear LCD Display: A clear, backlit matrix panel presents active flash parameters, group allocations, and mode settings at a glance, remaining highly readable in both bright daylight and pitch-black venues.
Dual Power Source Capabilities: Powered natively by four standard AA batteries (Alkaline or NiMH), yielding up to 330 full-power flashes per charge with rapid recycle times ranging from 0.1 to 2.6 seconds. Includes an integrated external high-voltage power terminal to connect specialized battery packs like the Godox PB960.
USB-C & Wired Sync Interfaces: Houses a standard USB Type-C port to install future system firmware upgrades. Features a 2.5mm hardwire sync terminal for basic wired connectivity with legacy camera bodies or third-party trigger blocks.
Dual Monitoring Capabilities: Traditional optical pulse master/slave transmission profiles remain fully integrated, allowing for cross-compatibility with standard non-radio optical trigger systems.
Kit Inventory & Complete Package Details
Functional State: FULLY OPERATIONAL. The flash tube fires cleanly across all power levels, the auto-zoom mechanism tracks smoothly, the radio transmitter registers instantly, and the locking hot shoe clamp secures firmly.
Cosmetic Presentation: EXCELLENT CONDITION. The speedlight housing is clean and structurally sound, showing minimal handling wear. The front optical panel and integrated bounce card slide assembly are unmarred.
