What Are Wet Conversion Lenses?

Wet lenses — also called conversion lenses — are mounted to the front of your underwater housing. They alter the effective focal length of your camera, giving you the ability to shoot extreme close-ups or fit more into your frame. This versatility is perfect for any dive photographer who wants to adapt to different scenes without changing gear topside.

Wide-Angle Lenses: Capture More of the Scene

A wide-angle wet lens is ideal for photographing large subjects like shipwrecks, turtles, or groups of divers. It allows you to get closer to your subject while still capturing the entire scene — improving clarity, color, and impact.

Popular SeaLife Wide-Angle Options:

• SeaLife SportDiver Wide Angle Dome Lens 15cm: A large dome lens with reduced edge distortion and a dramatic wide field of view. Perfect for vibrant reef scenes and large marine life.
• SeaLife SportDiver 52mm Wide Angle Dome Lens: Designed for the SeaLife SportDiver smartphone housing. Turn your phone into a true wide-angle camera — ideal for underwater video and stills.

Macro Lenses: Focus on Tiny Details

Macro conversion lenses let you get extremely close to your subject, revealing textures and details that are invisible to the naked eye. They’re perfect for capturing nudibranchs, shrimp, or coral patterns — with brilliant sharpness and contrast.

Combine With SeaLife Lighting

Underwater lighting makes all the difference. Pair your wet lens with a high-quality strobe or video light from SeaLife for vivid colors and sharp contrast. Explore our full selection of SeaLife strobes and lights.
