SeaLife Ultra Wide Angle Dome Lens - Micro Series & RM-4K (SL052)

• Get 3x closer and 43% wider field-of-view
• Optimizes edge-to-edge sharpness
• For SeaLife Micro-Series & RM-4K Cameras
• Removable lanyard included

The Micro Wide Angle Dome Lens for Micro-series and ReefMaster RM-4K underwater cameras increases the camera’s field-of view by almost 50% and allowing photographers to get three times closer to the subject.

The Micro Wide Angle Dome Lens design uses high-grade optics arranged in a 4- element/4- group array that delivers crisp edge-to-edge sharpness. The internal elements are fully multi-coated optical glass. The dome lens is optical polycarbonate with hard, anti-scratch coating. The lens has a 13.3mm film-equivalent effective focal length when used with the SeaLife Micro 3.0 and is waterproof to 200ft/60m.

The lens fits all SeaLife Micro-series cameras (Micro HD, HD+, Micro 2.0, Micro 3.0) and also works with the SeaLife ReefMaster RM-4K increasing the tiny camera’s shooting angle to a massive 196°. The Micro Wide Angle Dome Lens increases the Micro 3.0 shooting angle by 43% to 143° (in air) and allows the user to get almost 3x closer to the subject.

The Micro Wide Angle Dome Lens is a “wet lens” and easily attaches and removes underwater. A locking ring prevents the lens from accidently detaching when bumped or in rougher water conditions.  The lens weighs 11.7 ounces (331 grams) and is negatively buoyant. A lanyard is included to prevent loss underwater and the lens can dock on the Lens Caddy (SL091) when not in use.
