Snap great top-down shots with our new lens Porthole!

[AVAST Marine]

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.

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