Cameta Digital & Film SLR Macro Photography Kit: Ring Light Flash + NiMH Charger & Batteries + Macro Close Up Lens Filter Set - For Canon, Nikon, Olympus & Pentax Lenses with 58mm Filter Size

***
i purchased this kit for use with an olympus e-500 digital camera. not having used the batteries or charger, i have no comment on them. the bower close-up lenses, 4+, 2+, 1+ used individually or in tandem seem to provide magnification with no apparent loss in resolution. the cobra macroflash unit is useless. problem one: whether used in auto or manual mode, flash output was never consistent: usually too little or too much; seldom acceptable. two: because the battery compartment is an integral part of the flash, its bulk made usage cumbersome, especially since the battery compartment, according to instructions, is supposed to be parallel to the ground and proper tightening of all components seldom puts it there. the 58mm. adapter tended to bind to my u.v. filter so that filter, adapter, flash came off together. separating the filter from the other pieces was often very difficult. at least with my camera, this flash unit will not suffice for close-up work. and bear in mind as well that were it to function properly in auto mode on your camera, the output is synchronized at f5.6 which will not render adequate depth-of-field for macro work.
