Focus setting of rendering portrait camera

The focal length of the rendering portrait camera is set as follows

The first step is to find the camera insertion in physics.

Step 2: Drop down to find the physical camera and click the check box to enter.

Step 3: Move down and you will see that the focal length attribute is set to 40 mm..

When shooting a still life lens with a standard definition camera, the zoom ring is usually used to zoom to the maximum focal length and then focus accurately, and then it is changed to a preselected short focal length, that is, the target close-up focusing method.

However, this method is not suitable for the focusing requirements of high-definition camera technology, because the zoom lens has a small amount of image surface drift, and the best focusing position under different focal lengths may not be accurate and consistent.
