The **Godox AK-R1** is a pocket flash accessory kit designed specifically for round-head flashes (like the V1 series) or the AD200/AD200Pro with the H200R round head. While the kit itself consists of passive optical modifiers, its functionality relies on specific electronic integration with the flash unit. --- ### 1. Electronic Interface & Mounting The primary electronic "part" of the AK-R1 system is the **Magnetic Mount Interface**. Unlike traditional velcro or plastic clip-on modifiers, the AK-R1 uses a ring of magnets. | Component | Function | Electronic/Physical Role | | :--- | :--- | :--- | | **Magnetic Ring** | Alignment | Ensures the modifier is perfectly centered over the flash tube for optimal light spread. | | **Metal Attachment Point** | Security | Allows for "stacking" multiple modifiers (e.g., a gel + a grid) without interfering with the flash's cooling vents. | --- ### 2. Interaction with Flash Electronics The AK-R1 modifies how the flash's internal electronics manage output and heat: 1. **Heat Management:** High-end flashes like the V1 have thermal protection sensors. Using AK-R1 modifiers (especially the Snoot or Grids) restricts airflow. The flash's internal firmware monitors this to prevent the plastic modifiers from melting during high-power bursts. 2. **Light Distribution:** The kit includes a **Semicircle Diffuser (Dome)**. This helps the flash’s wide-angle zoom electronics by spreading light 180 degrees, simulating a bare-bulb effect. --- ### 3. Key Components in the Kit The kit includes several tools that manipulate the electronic light source: * **Green/Orange Gels:** Used to balance the color temperature (Kelvin) of the LED modeling light and the Xenon flash tube with ambient light. * **Honeycomb Grid:** Constrains the beam angle to a narrow point. * **Four-Way Barndoors:** Manually flags light to prevent spill into the camera lens. * **Bounce Card:** Redirects a portion of the electronic flash burst forward while the head is tilted upward. --- ### 4. Compatibility Table The AK-R1 is designed to interface with the following electronic units: | Device Type | Compatibility Method | | :--- | :--- | | **Godox V1 / V1Pro** | Native Magnetic Round Head | | **Godox AD200 / AD200Pro** | Requires H200R Round Head Attachment | | **Godox AD100Pro** | Native Magnetic Round Head | | **Rectangular Speedlights** | Requires S-R1 Magnetic Adapter | ---
