In the follow-up, the key point is to ensure the camera to focus continuously when moving, which is difficult for SLR to do, not only to have high stability, but also to keep the distance between the subject and the camera photosensitive element relatively constant. No matter what lens you use, the hard truth about stability and focal length is the same. The auxiliary devices for subsequent shooting are mostly guide rails, slide rails, camera stabilizers and even rocker arms. As for which brand is good, this can only be a matter of opinion. But you certainly won't buy expensive foreign goods. Speaking of domestic products, I use Mov Dream Series, which is made in China, cheap and practical.

Flash, shooting video can basically be ignored, because the light source used for camera shooting is different from photography, and it is all cold light source. For example, a small LED movie lamp is usually enough to form a lamp. You must learn to use the reflector.
