The Raven’s Nose Light was specifically designed to offer several beneficial options to the photographer. It offers both an Auto and Manual Focus Assist light, and Fill light.
Auto and Manual Focus Assist light
Customize your menu settings to have the Focus Assist light automatically turn on when your camera is focusing. When selecting Auto or Manual Assist lighting you have the option of red or white light. With the Ravens position in the hot shoe, it sits high enough above the lens and lens hood so that it properly lights that target you are focusing on with a small boost of light to lock in razor sharp focus. Additionally, having the option of using white light is a huge advantage to mirrorless cameras, since mirrorless cameras cannot use the conventional AF Red assist light due to sensor filters and cannot see the IR assist beam.
Another feature that sets the Raven apart from its competitors is the Fill light which offers a color temperature range of 2700K to 6500K, as well as the ability to adjust the brightness of the Fill light making it perfect for macro or wedding ring images.
