A real “Fisheye Lens”

[Glenner’sreef]

How many would be marine photographers have used their magnetized Flipper Magnifier to shoot through to get that awesome closeup of your favorite fish or coral?
I sure do. It doesn’t always work, but when it does, you can achieve some truly nice shots!

Glad it is working for you. My fish won't stop to pose so I have to track them with the camera and could not do that through a lens on the tank. For closeup I just crop the image. Maybe for coral it would work.
