The Godox SK400IIV D Studio Flash Kit is compatible with Nikon Z6ii cameras when used with a compatible wireless trigger like the Godox XPro-N or XT2-N. The kit itself may not include a trigger, but Godox triggers designed for Nikon systems work with the Z6ii, as confirmed by user reports. For optical triggering, the flash's built-in optical slave mode can sync with any camera flash. Ensure the trigger's firmware is updated for optimal performance.
