1. Is it divided into Canon mouth, Nikon mouth, Sony mouth?
Universal flash, single contact, off-camera support high-speed synchronization, Canon Nikon Sony camera, only need to select the corresponding transmitter, you can trigger the 850 second-generation flash.
When Pentax Olympus Lycra uses this flash, it can only be used as a manual light on the top of the camera, and it does not support high-speed synchronization.

2.Is there a built-in receiver?
Built-in x1 receiver, support x1 transmitter and xtr32 transmitter to trigger flash.
3.What is the difference between the 850 generation and the 850 second generation?
1), Increase the built-in 2.4G wireless transceiver module, support 2.4G wireless master control slave function, can be used with X1 trigger to trigger off-camera flash, no need to install a receiver;
2), Upgraded the lamp power, GN value increased to 60 index, more power, stronger illumination;
3), Upgraded high-speed synchronization, fully replaced the circuit module, with X1 trigger to achieve true 1/8000 full-range high-speed synchronization, 1/1~1/128 power full-range 1/8000 high-speed synchronization, the synchronization speed is no longer limited by the power size;
4), Upgraded the focal length of the lamp head, the zoom range has been upgraded from the first generation 24-105MM to 20-200MM, and the coverage is wider
4. What is the difference between the 850 second generation and the 860 second generation?
1), V860II supports a full range of TTL automatic metering functions. In TTL mode, the flash automatically sets the light output value according to the current environment and camera parameters, without manually setting the flash parameters; V850II does not have TTL function;
2), V860II flash mode supports front-curtain synchronization and rear-curtain synchronization; V850II Canon port does not support rear-curtain synchronization because it has no ttl function. Nikon Sony cameras use V850II, which supports rear-curtain synchronization;
3), V860II lamp holder zoom supports A/M mode(Automatic/manual mode), In auto mode, the focal length of the lamp head will automatically zoom with the focal length of the lens; V850II does not have the A mode automatic zoom, only the M mode can manually adjust the focal length of the lamp head;
