Can the SLR lens be fitted with that round soft light?

SLR also has this kind of ring light for macro shooting.

The lamp tube of the ring flash lamp surrounds the front end of the lens in a ring shape. Its main control unit can be inserted into the hot shoe of the fuselage and connected with the lamp holder through the connecting wire.

Ring flash is the best choice when shooting at close range or macro, because in these shooting tasks, ordinary set-top box flash often causes disturbing shadows. In addition, when shooting jewelry and portraits, and in some scientific or medical photography, the ring flash can also show its talents.
