Mine is a 580 2-generation 5d2 lamp. Now I want to buy [Cable Release] and [Flash Line]. Which is better, wired or wireless? What brand is good?

580 second-generation flash itself supports wireless main flash and wireless trigger flash. It is recommended that you must buy a wireless flasher when using this lamp. The original Canon st-e2 matches this flash well, but the price is too high. 1.500 yuan. The domestic flasher Yongnuo st-e2 has the same or even stronger flasher function as the original flasher, and the price is lower than that of 600 yuan, so it is recommended to buy Yongnuo st-e2. Although the wired camera ensures the quality of the flash, it is inconvenient to use. The camera must be mounted on a tripod to make room for holding the flash. The distance is limited and the sidelight effect is not obvious. Unless you want to use this lamp to add a line for macro photography and fix it in front of the lens with a powerful clip or something, this line will be better.

The wired release cable is better. The wireless shutter signal receiver of the camera is often installed in front of the camera, and the wireless shutter remote controller is often ineffective. A wireless remote controller with strong transmission in buying signal is needed, but the price is higher.
