Can Sony A7III work on pro-weddings in 2026?

[forumgetassist]

I intend to change my B-cam, but I have limited funds. The sony a7iii is still on sale at a discount on the used market. Is the autofocus still good at high-speed ceremony shots or should I just wait to get the A7IV? I have also found some review mixed reactions with the forum getassist regarding its low-light capability relative to the newer models. Were anyone to use this horse of burden in the field!
