The Sony HVL-RLAM Ringlight is a continues light source that makes it possible to consistently capture correctly lit macro images everytime. By attaching the Control Unit to the Alpha SLR camera's accessory shoe it is now easy to take well-lit extreme close-up pictures.
The HVL-RLAM features adjustable positioning so you can shoot through the ring light or have it offset from the lens. It also features induvidual control of the two lamps. The dual light tubes can be turned on simultaneously or separately. Using only one tube creates modeling, which can give a three-dimensional feeling to the subject.
