Canon 5d2 Sigma 24-70 Wedding Follow-up?

This configuration is very suitable for wedding follow-up.

General professional wedding photographers abroad are equipped with dual cameras (now generally Quan Huafu), and then the lens is ternary, such as Canon's 16-35L, 24-70L and 70-200L.

This is a configuration that can be attacked, retreated and defended. It's a little reluctant to connect 24-70 with APS-C format, but now you are a full-frame machine, and 24-70 is only the most commonly used focal length. Under limited conditions, I think it is the most reasonable configuration.

As for Sima or Canon, it doesn't really matter. Good luck.
