Product Information
The SeaLife Micro Wide Angle Dome Lens (SL052) is a wet lens built for SeaLife's Micro-series underwater cameras (Micro HD, HD+, Micro 2.0, Micro 3.0) and the ReefMaster RM-4K, using a 4-element/4-group fully multi-coated optical array in an anti-scratch optical polycarbonate dome, and it is depth rated to 200ft/60m.
Who it is for
This lens is for SeaLife Micro-series and ReefMaster RM-4K owners who want a wider field of view and closer focusing without changing cameras. It is a push-on wet lens, so it can be added or removed while the camera is submerged, and it docks on the SeaLife Lens Caddy (SL091) when not mounted.
Key details
The optical array is 4 elements in 4 groups with fully multi-coated, anti-reflective air-to-glass surfaces, delivering a 0.7x underwater magnification ratio. On the Micro 3.0, field of view increases from 100° to 143°; on the RM-4K it increases from 140° to 196°. Focus range is 5 in (12.7cm) to infinity on the Micro 3.0 and 4 in (10.16cm) to infinity on the RM-4K. The lens body is black hard anodized Type III aluminum, the dome is anti-scratch coated optical polycarbonate, and the unit weighs 331g (11.7oz) on land and 170g (6oz) underwater with negative buoyancy. It attaches with a push-on locking ring that can be used on land or underwater.

The Micro Wide Angle Dome Lens fits the SeaLife Micro HD, Micro HD+, Micro 2.0, and Micro 3.0, as well as the SeaLife ReefMaster RM-4K, and it docks onto the SeaLife Lens Caddy (SL091) for storage between dives.

Frequently Asked Questions
Which SeaLife cameras work with the Micro Wide Angle Dome Lens?
It fits the SeaLife Micro HD, Micro HD+, Micro 2.0, and Micro 3.0, as well as the SeaLife ReefMaster RM-4K. It also docks onto the SeaLife Lens Caddy (SL091) when not attached to a camera, so it can be stored between dives without disconnecting from your gear setup.
Can the Micro Wide Angle Dome Lens be attached or removed while diving?
Yes. It is a wet lens with a push-on locking ring that attaches and detaches on land or underwater. The locking ring is designed to keep the lens seated on the camera so it does not come loose if bumped or used in rougher water conditions.

Focus range depends on the camera: 5 in (12.7cm) to infinity on the SeaLife Micro 3.0, and 4 in (10.16cm) to infinity on the SeaLife ReefMaster RM-4K. This lets you shoot noticeably closer to a subject than the camera alone.
