Want to take great top-down shots?

This little lens housing mounts directly to your SLR camera's lens barrel, allowing you to dip the lens underwater and get nice top-down shots without wavy distortions or light bulb reflections. Unlike traditional top-down boxes which are usually bulky and hold the entire camera, this one spins with the lens allowing easy zoom/manual focus.


Features a machined texture on the outer barrel for firm grip, plus a protective ring to help keep the acrylic lens from scratching when the housing+camera is set face-down. Three simple thumbscrews lock the housing to most any SLR lens in seconds (housing has 4" inner diameter). It may even hold some smaller point-n-shoot cameras too.

More details here:

Here is some discussion from our local reef club from members who have gotten their hands on one already:

Hopefully this can turn into a photo sharing thread with pictures taken using the porthole.

Great pics! That clam looks amazing.

I'm glad to see that it works well for you with standard gear and basic photography knowledge.

would like to see it mounted to an outfit and see what it looks like on a canon body with a macro lense and a 28-135 will it fit any lense or just certain type of lenses?
