[Acrylic, Delrin] These redesigned ports are much easier to screw and unscrew B&H notified me once they were back in stock definitely worth the wait

[0.855 lb] It's exactly what it's supposed to be

[Clear / Black] Much improved over the Elite series ports.

[Acrylic, Delrin] It's mostly a matter of pure functionality. Needed a proper way to protect my Aquatech PD-135 dome port. This does the job it's supposed.

[8.3 x 6.9 x 4"] Let me start with a simple summary, I love it, and it's worth the investment.
I used it a lot for several years, but nowadays, I'm taking a break from underwater photography because I relocated, and I am still trying to find opportunities to apply this type of photography in the new area. Yes, it's heavy, but once you are in the water, this minor disadvantage becomes invisible, or better said, unnoticeable.
When I did my first underwater photoshoot in the sea, I was scared, and the question, What if... was constantly creating new horrifying scenarios, like What if I didn't close it good enough, What if there is a tiny crack and the water gets inside, What if I'm not able to focus correctly None of this scenarios became true, lucky me, and it also proves good quality product.
After several intense photo sessions, I noticed a small crack in the focus lever, so I contacted the support team. The communication was fast and productive; they sent me a replacement almost immediately and didn't charge me anything. Considering my location at that time (Cancun, MX) I was amazed at how fast I got the package with the new lever. I replaced it easily and never had issues after.
Learning to focus underwater will take time, but all good takes time, right?! Mounting it all together usually took me 15-20 min as I double-checked every lock. I used it with Nikon D750 and 16-35 Nikkor lens.
The quality of the photos is excellent, especially when the water is clear.
Hopefully, I'll have a chance soon to enjoy more of underwater photography.

[Acrylic, Delrin] Just what we needed for shooting indoors and jelling windows.

[0.855 lb] I bought this about a year ago to do some underwater photography in Barbados. The housing worked great with my D850 with a 28mm Nikkor prime. Make sure to carefully follow the directions prior to use and cleaning after use. It will float, so you may want to add weights to make it less buoyant. I used it for snorkeling, which made it hard to dive down with it. If you added a little weight, it would be much better. Also make sure to get as many settings set before putting the housing on, as it is more difficult to monkey with it once youre in the ocean.

[Clear / Black] Just make sure you put it on correctly, if not you have start over with pulling the lens off.

[Clear / Black] My husband intends to use this on our 16-35mm lens with our new RED camera for capturing video images of sharks and other large marine wildlife.
