So much flash fo little money! It is purely manual. So only buy if your digi-cam can save your photos as RAW files ready. These are like negative film of the analog era: roughly estimate exposure, then click like crazy, only then correct the computer exposure (what happened when negative film in the industrial laboratory). * It is supplied with a huge tobacco pouch with inner partition. A tip moderate quivers for storage of lightning! * The flash foot has a locking lever, which is so convenient that it represents the push button of Olympus and the locknut of Metz in the shadows. Try yourself! * The connecting cable between the generator and lightning is so thick and solid, as if it were for the electric chair and not a photo-flash. * The connection of the flash disks, which are screwed into the filter thread of the lens, are the same that uses the Coki-P-filter system. The flash itself is secured with 4 sprung claws, which you can easily retract by pressing two buttons on the flash ring on the discs. * The operation is logical and simple. Means the most to have read even without the operating instructions. * I have the flash on my Oly-Zoom. 14 - 150 mm II + Marumi-up lenses 3, 5 or both = 8 dpt used. Is good photos. Cheaper Macro photography is no longer. * Lightning has real "steam". I had 11-regulate down to 1/64 at f him. He illuminates an entire room, the un at aperture 8. At full wide-angle (14 mm = 28 mm small picture) the corners werdn not fully illuminated. So in case of non-Macro rather for portraits! What more do you want?
* Why no original Oly flash? The is no longer made. When there was him, he was very expensive. So little macro photos as I would shoot, so as to be worth a purchase? * How long does this flash, finally he comes from China, and China goods often does not last long? To which I can not answer today.
