Judging from the size of photoelectric equipment, VG20 is about 8 times larger than Z5C.

So in terms of image quality, VG20 is much better than Z5C.

Judging from the lens, the VG20 can change the lens and use Zeiss's head.

And Z5C is a 20-fold fixed-focus lens, Fuji long lens (G lens)?

So VG20 imaging is much better than Z5C. .

But in operation, VG20 is more similar to SLR, and its handling is not as good as Z5C. After all, Z5C is a Sony business-class series product.

If we start from the wedding, there will be a lot of light environment and a lot of follow-up. . . . .

VG20 may not be suitable.

If you want to choose a camera, the first choice is Z7C, and the lens is good. The picture taken by Z5C is too gray and opaque.

Regarding the parameters of VG20, there is an article in my Baidu space about the evaluation of VG 10. You can refer to it
