Fish Eye Camera 8mm Lens
This lens can be swapped over to replace the standard 3.6mm lens supplied with the original Fish Eye camera kit.
The 8mm lens has a more magnified effect than the standard 6mm and 3.6mm lenses. 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 15ft 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 standard 3.6mm or 6mm lenses, producing you a narrower, more focussed view.
