What kind of cameras and lenses should children's photography shops use?

Because children are active and easily disturbed by the outside world, children's photography requires a higher aperture. A larger aperture can ensure the shutter speed and avoid using flash as much as possible, which greatly improves the chances of making a good film. So no matter what camera you choose, a head is necessary, such as 50 1.8, or 50 1.4 with a larger aperture.

In addition, the 450D camera should still be available in the market, while the price of the 500D camera is 5000+ points. What I want to say is that, to a certain extent, the imaging effect is closer to the "head" in front of and behind the camera.
