PORTHOLE HOUSING IS NOW BLACK.  NEW IMAGE COMING SOON!

Take great photos of your aquarium from the top down, the way corals are meant to be viewed!  This handy lens housing mounts directly to the barrel of your DSLR lens, allowing you to (carefully) dip the housing in the water and get tack sharp photos without annoying lightbulb reflections or surface ripples.  Using the three thumbscrews to mount the housing on the lens barrel, you can turn the housing to zoom the lens, which can be difficult with traditional top-down photo boxes.

The Porthole features a silicone band for extra grip, and lens standoffs to protect the acrylic from scratches when set face-down.

Inner diameter of the housing is approximately 4" and supports a wide range of lens sizes.  The housing length is 7" overall, and the barrel depth is 6-3/8" to the inside of the acrylic lens.   This allows compatibility with external-focus/zoom lenses and large macro lenses.

Many thanks to our friend Chris Thomas (143gadgets) for the photos taken with the Porthole.  As a professional photographer, he has provided us with valuable feedback during the product's design.

Great product!

The pothole worked like a charm. Easy to attach to my lens and very nicely made, it felt like a quality product. My only suggestion would be to have flat ends on the screws so it doesn't leave scuffs/marks over time on the lens body.

Works great!

Great build quality and design. The ports large enough to fit a large hand inside for polishing in the future.

porthole 911

Avast is the best! I had an accident and broke my ages old porthole for shooting coral. I contacted them about getting a new because they were sold out at the time. They took immediate care of me, modifying a longer model to suit my needs, and had it out the next day. It doesn't get much better that that. thanks again!
