Product Information
The SeaLife Super Macro Lens (SL571) is a wet close-up lens for the SeaLife Micro-series and ReefMaster RM-4K cameras that adds 2.5x to 3.5x magnification underwater, letting divers and snorkelers capture macro images and video of subjects as close as 3.5 inches (9cm) away. It attaches with a quick rubber press-on mount and is built from an anodized aluminum body with rubber armoring around a 2-element optical-grade glass lens.
Who it is for
This lens is for SeaLife Micro-series or ReefMaster RM-4K owners who want to shoot small reef life, nudibranchs, shrimp, and other macro subjects without carrying a separate macro camera. Because it is a wet lens, it is used only underwater, where water fills the space between the lens and the camera lens to achieve correct focus and magnification.
Key details
- Magnification: 2.5x to 3.5x underwater (+10 diopter lens)
- Capture range: 3.5 inches to 7 inches (9cm to 18cm)
- Minimum focus distance: approximately 3.5 inches
- Depth-of-field: 2 inches to 3.5 inches depending on camera model
- Waterproof rating: 200ft (60m)
- Weight: 2.4oz (69g), negative buoyancy
- Body: anodized aluminum with rubber armoring; 2-element optical-grade glass with anti-reflective coating
Compatibility and sizing
The lens fits the SeaLife Micro 3.0, Micro 2.0, Micro HD, Micro HD+, and ReefMaster RM-4K cameras via a rubber press-on mount. Focus range is 4 inches to 6 inches (10cm to 15cm) on the Micro 3.0, and 3.5 inches to 7 inches (9cm to 18cm) on the Micro HD, HD+, 2.0, and RM-4K cameras.

Frequently Asked Questions
Which SeaLife cameras work with the Super Macro Lens?
The Super Macro Lens (SL571) is compatible with the SeaLife Micro 3.0, Micro 2.0, Micro HD, Micro HD+, and ReefMaster RM-4K cameras. It attaches to each of these models with the same rubber press-on mount, though the usable focus range differs slightly between the Micro 3.0 and the other compatible cameras.
How close do I need to be to my subject with this lens?
Focus distance depends on the camera. On the Micro 3.0, the usable range is 4 inches to 6 inches (10cm to 15cm) from the subject. On the Micro HD, HD+, 2.0, and ReefMaster RM-4K, the range extends from 3.5 inches to 7 inches (9cm to 18cm), with a minimum focus distance of about 3.5 inches.
Can I use the Super Macro Lens out of water?
No. The SL571 is a wet lens, meaning it is designed to have water between it and the camera's lens to achieve correct focus and its rated 2.5x to 3.5x magnification. The press-on mount can be attached or removed on land, but image quality and magnification are only accurate when shooting underwater.
What is included with the Super Macro Lens, and how deep is it rated?
Each SL571 comes with the lens itself, two removable focus distance sticks (4.5 inches / 11.4cm), a safety lanyard, and a protective pouch. The lens is depth rated to 200ft (60m).
