5D2 has high image quality, good low illumination effect and small depth of field.

Very suitable for "micro-movies".

The wedding depends on what kind of wedding you plan to shoot.

Traditional follow-up, AX2000E is suitable.

But if you want to shoot something with pictures and colors. It is more appropriate to use a large format 5D2.

It's appropriate to start with two or three.

It depends on your wedding.
