5D2 with 24- 105 basically does not need to change lenses, which is very convenient. However, as a wedding photo, the imaging quality is worrying. The reason is that in domestic weddings, the small aperture of F4 makes the depth of field very large. Even if the excellent expression of the protagonist is captured, there may be various kinds of crossing in the background, such as squinting at others, playing mobile phones, chatting by yourself and so on. Therefore, it is recommended to change the fixed-focus lens if possible.
In terms of wedding equipment, the prices are basically low-end weddings, so it is very unnecessary to deal with such weddings. Improving the quality of photos (whether in the early or late stage) is the king. This kind of equipment is in Chengdu, and there are many people who receive 500 yuan for wedding cooperation.
The increase in price depends on your technology, not just the machine. Good luck.
