What camera should I use for the wedding?

What camera to use to see personal conditions. If you have money, you must buy something better, such as:

Sony PXW-Z 150

And Sony HXR-NX3 or Sony HXR-NX5R.

If you buy something lower, you can buy:

Sony HXR-NX 100

Or JVC JY-HM360.

Want to buy only at a low price:

JVC JY-HM95

And Sony HXR-MC2500.

These big-shell cameras, with a big shell at the core of the household machine, become professional machines. I don't think it is necessary to use a professional machine with more than 30 thousand yuan. Let the professional users such as TV stations use it. It's too expensive to take back the wedding machine.
