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.

Overall happy

The port-hole works very well. I did notice some scratches on the lense the day after I got it. This could be from me wiping the lense but nontheless, the plastic is very sensitive even with soft towels.

Awesome

Purchased this product a couple weeks ago. When I received it , it had a minor scratch in the bottom lense. I emailed Avast and I had it shipped back for an exchange. Avast was fantastic and had it back to my door in less than 4 days. I love the customer service Avast gives and the great quality products. I’ve taken a lot of great shots with this porthole using my Macro lense. Awesome piece of Kit. Thanks guys. Another loyal and happy customer.

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.
