The cheapest (SLR) camera to shoot fast moving objects without blurring? Or what parameters are the key to the camera shooting moving objects without blurring?

The dynamic target is not blurred, and the shutter speed needs to be increased. If you want to ensure the quality, you must increase the aperture and iso value. Theoretically, only SLR can realize it. The entry-level SLR Nikon D3 100 is around 3000 yuan, and Nikon D5 100 is around 4000 yuan. This is just a bare machine with a lens. Your request must be matched with a large aperture lens, which is expensive. If the aperture is above 2.8, it is generally above 10,000 yuan. The so-called integrated SLR poor three generations is like this. I advise you to give up this idea Your request seems simple, but in fact it is difficult to achieve.
