Enhance your underwater photography with the removable Magenta color-correction filter for the SeaLife SportDiver. This filter restores natural underwater colors, making it ideal for green water conditions. It is most effective at depths of 10ft/3m to 60ft/18m, with or without external lighting. Additionally, it serves as a protective cover for the SportDiver’s optical glass port. Designed for compatibility with the SeaLife SportDiver and SportDiver Ultra underwater smartphone housings, this filter attaches and removes easily from the SportDiver optical lens frame while underwater. Constructed from optical acrylic infused with proprietary color pigments, it ensures durability and clarity. The filter also includes a lanyard for secure attachment to the housing. For optimal performance in blue water, consider the Red Color-Correction Filter, item SL40007.
