Description Backscatter M52 Wide-Air Lens Enhance Your Underwater Photography with the Backscatter M52 Wide Air Lens The Backscatter M52 Wide Air Lens is a game-changer for the Olympus TG series of underwater camera systems. Designed specifically for underwater shooting, this wet-mount lens delivers superior edge-to-edge sharpness, minimal distortion, and a wide 81-degree field of view—perfect for capturing stunning reefscapes, large marine life, and immersive dive scenes. The Backscatter Wide Air Lens ensures vibrant, true-to-life colours and high-contrast images in even the most challenging underwater lighting conditions. Its air lens design reduces the water-to-glass interface, improving image clarity and reducing aberrations common in underwater photography. Whether you’re a seasoned professional or an enthusiastic beginner, the Backscatter Air Lens is lightweight, easy to attach, and compatible with any housing featuring a 52mm threaded port. Its compact form factor makes it an ideal travel companion for any dive trip. M52 Air Lens NOT Compatible With No-Burp O-rings Why do we use a wide lens for underwater photography? 1. Capture More of the Scene Water limits visibility, so you often need to get closer to your subject to reduce backscatter and improve clarity. A wide lens lets you: Get close without cutting off parts of the subject (like large animals, reef structures, or wrecks). Include more background or environment, creating dramatic, immersive images. 2. Reduce Backscatter Backscatter happens when your strobe light hits particles in the water between you and the subject. With a wide-angle lens, you can: Get closer to the subject. Use your strobes more effectively at a shorter distance. Minimise the amount of water (and particles) between the lens and the subject, leading to cleaner, clearer shots. 3. Improve Sharpness and Contrast Wide-angle lenses designed for underwater use are optimised to: Minimise distortion and edge softness. Provide crisp detail across the entire frame, even in underwater conditions. Maintain vibrant colours and contrast that might otherwise be lost. 4. Ideal for Large Subjects If you’re photographing: Wrecks Coral reefs Schools of fish Large animals like manta rays, sharks, or whales Difference Between 81° and 120° Wide Angle Lenses 1. Field of View (How Wide the Image Is) 81° Lens – Moderate wide-angle coverage 120° Lens – Ultra-wide coverage The 120° lens captures significantly more of the underwater scene in a single frame, making it ideal for large subjects such as reefs, wrecks, sharks, and divers. A wider angle also allows photographers to get closer to subjects while still fitting more into the shot. The 81° lens, on the other hand, provides a more natural perspective that is closer to the camera’s native field of view. 2. Shooting Style 81° Wide Angle Lens Balanced wide view Great for mixed shooting (macro wide in one dive) Less distortion Often allows full zoom-through for tighter shots 120° Wide Angle Lens Ultra-wide perspective Best for large underwater scenes and close-focus wide shots More immersive reef and wreck photography Allows photographers to get closer to subjects while maintaining a wide frame. 3. Lens Type Difference Feature 81° Lens 120° Lens Field of View 81° 120° Lens Type Air lens Wet wide-angle lens Shooting Flexibility Macro wide Primarily wide-angle Best For General diving photography Large scenes & reefscapes The 120° lens is a wet wide-angle lens designed for dramatic underwater coverage, while the 81° air lens is more versatile for everyday shooting without removing the lens. Simple Summary 81° → versatile, natural wide angle, good for macro wide shooting 120° → ultra-wide, best for reefs, wrecks, divers, and large marine life A wide-angle lens is essential. It lets you fit the entire subject into your frame without having to swim too far away, which would decrease visibility and sharpness. Check out other lens we have in-store.
