Fish Eye Camera 6mm Lens
This lens can be swapped over to replace the standard 3.6mm lens supplied with the original Fish Eye camera kit.
The 6mm lens has a more magnified effect than the standard 3.6mm lens. Under the water this can be useful to see smaller areas of the bottom in more detail (water clarity permitting) - good for a closer view in up to 10ft of water. Above the water it will make things look closer than they actually are.
The field of vision is not as wide as the 3.6mm standard lens, giving you a narrower, more focussed view.
