The price of 500 and 900 is similar, and the flashing light is less than 1000 yuan.

V850 is not worth it. You can buy two YN560 s of Yongnuo, and there is not much difference.

You can buy a second-hand factory that is made in China and automatic, and the price is similar to that of domestic automatic, but things are much worse.

The flash first looks at the "rotation angle of the lamp holder". The bigger the angle, the more convenient it is. The flashing light should flash. Then look at the GN value. The bigger the GN value, the stronger it is. Similarly, because the flash is mainly jumping, that is, reflecting light, the light loss on the way is great, so the larger the GN value, the better.

Call me back. It's no use if you don't have a wedding. If you don't look carefully, the callback speed is directly proportional to the price. High-speed synchronization is even more useless, outdoor large aperture+high sense can be.
