Benefits: A reasonable priced auxiliary part of Olympus to objects up to max. Tennis ball size to take pictures with easy shadow extending macro-perspective. (2 light sources increase so visually the 3D effect of the object) Due to the flexible arm length 17cm, this requires an appropriate macro lens with focus distance from 15-20cm to also come to the side of the object for illumination - note! To succeed in a very beautiful, plastic, and artistic macro photos of mainly immovable objects due to necessary arm adjustment.
Disadvantages: Who scientific documentation, od. Movable objects has (eg. Insects in the wild) in mind, however, is a good Ringbitz, possibly with add. Adjustment ring illumination, better advice. - Then has a completely different price category ;-)
