This flash complements my equipment and allows me 1: 1 macro illuminate perfectly. I also take the opportunity of fully unleashed flashing and hold the flash in his hand to the light even more relevant to the object. Battery runtime as usual at Metz very good, Eneloops here are perfect. The coordination with the camera via TTL (Olympus E-520) is working properly and could be easily set up. I use generally the lens and had swung the reflectors; 3 - 1:: in this combination the object of 1 is 1 illuminated properly. The possibility to rotate the complete flash on the lens I use often to in difficult environments (branches, leaves, etc.) while still being able to throw the right light on the object. Unrestricted buy recommendation.
