Product Information
The SeaLife 6"/15cm Wide Angle Dome Lens is a 0.71x wet-mount dome lens that attaches directly to the lens port of the SeaLife SportDiver underwater smartphone housing, with no lens adapter needed, and increases your phone camera's underwater field of view by over 40%. It is waterproof to 130 feet (40 m), positively buoyant, and can be attached or removed while you are underwater.
Who it is for
This lens is for divers, snorkelers and freedivers shooting with a SportDiver or SportDiver ULTRA smartphone housing who want wide reef scenes, close-focus wide angle shots and above/below split shots. Because the field of view grows by 40% and focus distance is reduced by roughly 25%, you can move closer to a subject and still fit the whole scene in frame, which cuts the amount of water between lens and subject. No skill, training or adjustment is required: mount it and shoot.
Key details
- 0.71x magnification ratio, 2-element/2-group PMMA acrylic optical design for edge-to-edge sharpness and corrected barrel distortion
- Large 6.7" diameter x 2.7" height (17.0 cm x 6.9 cm) dome for easy split shots
- Fiber-reinforced polycarbonate body, scratch-resistant acrylic dome
- Built-in rotatable sunshade to control stray sunlight
- 17.4 oz (493 g) on land, positively buoyant by 13.7 oz (389 g) underwater thanks to air-filled inner lens chambers
- Depth tested to 130 ft (40 m); 1-year limited warranty; SKU SL053
Compatibility and sizing
Fits all SeaLife SportDiver and SportDiver ULTRA smartphone housings and mounts straight to the housing lens port without an adapter. Used with the SportDiver and the iPhone 15 Pro's 24 mm "Ultrawide" camera lens, for example, it delivers a 15.6 mm film-equivalent effective focal length. The included safety lanyard keeps the lens tethered to the housing if it is bumped off.

Frequently Asked Questions
Does the 6"/15cm dome lens need an adapter to fit the SportDiver housing?
No adapter is needed. The 6"/15cm Wide Angle Dome Lens mounts directly to the lens port of the SeaLife SportDiver housing, and it also works with the SportDiver ULTRA housing. It is a wet lens, so you can attach or remove it while you are underwater. A retaining lanyard is included to keep the lens tethered to the housing if it is bumped off.
How much wider does the dome lens make my phone's underwater shots?
It increases the field of view of your phone's native camera lens by over 40% with a 0.71x magnification ratio, and it cuts focus distance by roughly 25% depending on the native lens. Paired with the SportDiver and an iPhone 15 Pro's 24 mm Ultrawide camera, the combination gives a 15.6 mm film-equivalent effective focal length.
Will the dome lens sink if it comes off underwater?
No. The inner lens chambers are air filled, so the dome is positively buoyant by 13.7 oz (389 g) underwater, even though it weighs 17.4 oz (493 g) on land. It will float rather than sink. SeaLife still includes a lens retaining lanyard so the dome stays attached to your housing if it is knocked loose.
What is the depth rating and warranty on this dome lens?
The dome lens is waterproof and depth tested to 130 feet (40 m), and it carries a 1-year limited warranty from SeaLife. The dome itself is scratch-resistant PMMA acrylic and the body is fiber-reinforced polycarbonate. A neoprene cover and protective storage pouch are included to protect the optics between dives.
