1. Sync Hole Trigger: Supports cameras with a PC output port
2. Power Supply: Transmitter: 2 x AA batteries (not included); Receiver: Plug-in power
3. Flash Modes: TTL auto flash, manual flash, stroboscopic flash, high-speed sync, rear-curtain sync (must be set on the camera for FT433 S and FT433 N)
4. Exposure Compensation: +/-3 EV (exposure value), adjustable in 1/3 EV increments
5. Focus Assist: Available (requires camera support for this feature)
6. Modeling Flash: The flash’s modeling light can be controlled via the trigger (FT433 S does not support this feature)
7. Buzzer: The flash’s buzzer can be controlled via the trigger
8. Wireless Shutter: The receiver can trigger the camera via the 2.5mm sync terminal
9. ZOOM Setting: AUTO / Focal Length 24–200mm
10. TCM Conversion: Converts TTL exposure values to M output values
11. Firmware Update: Firmware updates via the Type-C port on the unit
12. Memory Mode: Settings are automatically saved after 2 seconds and restored upon restart
13. Display: Widescreen LCD display with adjustable backlight (on/off)

Features:
1. Built-in 433 MHz wireless module with strong anti-interference capability and signal stability. When paired with the FR433 receiver, the FT433 trigger supports 32 channels and wireless ID settings ranging from 0 to 99, enabling wireless synchronization of up to 16 sets of flash equipment simultaneously
2. Fully supports TTL automatic flash metering and High-Speed Sync (HSS) up to 1/8000 second, effectively meeting various demanding creative photography needs such as underexposing in bright environments and capturing fast-moving subjects
3. Supports multi-contact mode for full parameter transmission, as well as single-contact mode. In single-contact mode, the trigger and camera do not exchange additional data, resulting in faster continuous shooting speeds than multi-contact mode, meeting the demands of high-frequency continuous shooting
4. Features a TCM (TTL-Convert-Manual) conversion function. When enabled, TTL auto-exposure settings can be quickly converted to manual (M) mode settings with a single button press, simplifying the cumbersome metering process and reducing TTL pre-flashes to achieve energy efficiency and high performance
5. The base features a quick-release hot shoe latch design, ensuring quick installation and removal while remaining secure and durable
6. Supports Bluetooth connectivity, allowing remote control via a mobile app to perform complex operations such as adjusting flash mode, power output, and modeling light settings
