This is a bounce flash that supports swivel and tilt operation. * Normally, the pop-up flash built into single-lens reflex cameras and mirrorless cameras has a fixed flash position, and can only emit light directly forward, resulting in blown-out highlights, strong shadows, and unsightly, harsh results. To improve this, you have no choice but to introduce an external flash that supports bounce. * The FL-LM3 supports swivel and tilt, enabling bounce flash. * Compact yet GN9 at ISO100. * If used correctly, it can illuminate an entire medium-sized room. * No battery required. * The flash does not require a battery and can draw power directly from the camera. There's no need to worry about the flash battery running out or forgetting to insert it. * It can also serve as insurance in case of trouble with the main flash. * Dustproof and splashproof specifications to match OM-D cameras.
