6”/15cm Wide Angle Dome Lens for SportDiver


The 6”/15cm Wide Angle Dome Lens for the SeaLife SportDiver underwater smartphone housing increases the phone’s camera lens field-of view by 40% and allows photographers to get closer to the subject while fitting everything into the image frame. The new dome lens mounts directly to the SportDiver housing’s lens port without a lens adapter.

The 0.71x dome lens requires no skill, training, or adjustment; simply mount it and shoot. Split shots that split the topside view with the undersea view are especially easy. There’s a safety lanyard included to keep the lens with the housing should it get bumped off. The dome lens design uses high-grade acrylic optics arranged in a 2-element/2- group array that delivers crisp edge-to-edge sharpness. The lens has a 15.6mm film-equivalent effective focal length when used, for example, with the SeaLife SportDiver and the iPhone 15 Pro’s 24mm “Ultrawide” camera lens.

The lens is waterproof to 130ft/40m and is positively buoyant. The new 6”/15cm Dome Lens fits all SeaLife SportDiver housings. The dome lens includes a rotatable sunshade built around the optics to help control stray sunlight. The 6” dome lens is a “wet lens” and easily attaches and removes underwater, the inner lens chambers are air-filled, and the lens is therefore buoyant. A lanyard is included and prevents the lens from accidental detachment if bumped off.
