Top-Down Porthole

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.

Back by popular demand, our original "shorty" Top-Down Porthole now features attachment mechanisms for nearly every camera available!  Besides the original 3-screw DSLR barrel mount, the optional adjustable C-bracket accommodates nearly every smartphone out there.  Another optional angle mount connects any point-n-shoot camera with a tripod screw mount.  This is a recessed threaded hole in the bottom of your camera that is a standard size (1/4"-20 threading) for mounting to tripods.  

Dimensions: The inner diameter of the housing is approximately 4" and supports a wide range of lens sizes.  The housing length is 4" overall.

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.

Top Down Porthole

Item was delivered on time. Packaging was excellent. Build quality is top notch. Also ordered blue filter. Made corals in pictures come alive. In my opinion best porthole currently available.

Avast Porthole

As a beginner photographer, using the pothole has really opened up the possibilities of in tank photos and a macro lens. Plus it is extremely well built. Kudos Avast! Thanks!

Portal makes photos awesome

This is the second portal I’ve picked up from Avast for photography at my commercial coral farm and lab. Really makes a difference to eliminate surface of water from photos and get right on top of the corals. Pickup the phone mount to give an option of taking quick picks with my phone instead of the DSLR. This version is a bit shorter than the other, but will be good in our shorter frag/lagoon tanks under 12”. Would be a good option also for nano tanks. Solid construction as always from Avast.

It is very easy to use and helps take great pictures close up inside the tank.
