Quan Huafu's CMOS thin film has a good low illumination effect.
Wedding shooting, mostly indoor shooting, the scene illumination is very low.
So it fits.
The traditional small high-definition cameras are all 1/3(EX 1R is 1/2), and the low illumination is generally not good.
So it is not suitable for taking wedding photos.
As for the promotional film, the bigger the film, the better.
For information about cameras, please refer to my Baidu space.
