Excuse me, how to use this DV to shoot a shot that is close to reality and far from reality? Sony XR 150E

Theoretically, this DV can also achieve the effect of near reality and far virtual or near virtual and far real.

However, due to the small size of CCD or CMOS, it can only be realized under special conditions:

The object distance of 1 is very close and important;

2 the aperture is large enough, which is necessary;

The focal length is long enough, and this can be selected as needed. Of course, the longer the focal length, the better the virtual and real effect.

To sum up, this is not only a problem encountered by ordinary DV, but also a bottleneck problem for many card cameras and consumer cameras. In the final analysis, it is caused by the small size of photosensitive elements.
