What kind of camera is suitable for wedding location and indoor photo?

If you are looking for better picture quality, I think digital SLR camera is the first choice. The paraxial camera hasn't been touched, so don't comment.

Digital SLR, there is a lot of room for later modification, and most importantly, the film it made is already very good.

It depends on your budget. If the budget is available, it's best to buy some cameras above the mid-range, so that you can play more space, and the lens is an investment. I think you need at least a 24-70 equivalent lens and a large aperture telephoto lens, such as 70-200 or 85/F 1.4, 135F2 lens.

For example, you use Nikon,

I think it's best to use a fuselage above d300s. If the budget is limited, you can also use d90. As for the lens, we need a Nikon 17-55 F2.8 or a Longteng 17-50 F2.8 (if the budget is limited), and a 70-200 Nikon or sub-factory lens, or 85F 1.4.

If it is a full-frame camera, then d700/d3, the best lens is 24-70, 70-200/85F 1. four

In short, it is a wide-angle (can be super-wide) portrait of another person. This is the most basic.
