haven't used it yet, but overall great
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.
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!
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.
Works great and I was able to get clear top down photos.
