DLM 8 inch Dome Port

The newer DLM 8" Dome Port # 5516.82 is recommended for Sony, Canon, and select Panasonic compact mirrorless camera housings. See compatibility information below.

About this Product

Comparable image quality to glass yet several pounds lighter and easier to handle, especially at the surface of the water.

A new acetyl base allows the dome port to attach directly to a compatible housing with DLM port system and weighs only slightly more than our smaller diameter 6" dome ports.

Image Quality

The injection molded acrylic 8" diameter dome is specifically designed for underwater photography to provide superior optical performance. This dome provides image quality virtually indistinguishable from glass yet several pounds lighter and easier to handle, especially at the surface of the water.

Compared to smaller 4" and 6" diameter domes, the larger dome reduces edge distortion on pictures taken with certain super-wide angle lenses and makes shooting over-under shots (half-in, half-out of the water) easier.

Domes are ideal underwater for shooting wide angle and zoom lenses. If you're shooting a macro lens, we recommend using the a flat port instead.


For use with compatible housings featuring DLM/A, DLM/B, and DLM/C port systems. Refer to the appropriate lens port for your housing to determine compatibility. This dome port cannot be used with DL or FL port systems.

Fiber optic port placement on some housings prevent the dome from attaching to the front of the housing without an extension in between when using fiber optic cords. These housings include: 

  • Sony Alpha a6000 TTL # 6910.60 / 6910.61
  • Sony Alpha a6300 TTL # 6910.63

April/May 2022 Delays:

Due to further Omicron outbreaks in Hong Kong, some products may be delayed. Not all brands or products will be affected by this. As some products are kept in stock as a matter of course, these should be fine.

If you need things urgently please contact us and check ETA on the items you require.

How long will it take for my order to arrive after I make payment?

That depends on where you live and whether we have an item in stock or not. While we do have many items in stock, we don't carry everything. If you need an item in a hurry, it's a good idea to contact us and find out if your item is in stock.

If we have it in stock, we can usually send it out as soon as we receive payment, or you can pick it up. If an item is not in stock, we'll need to order it from our suppliers, which means it can take 1-2 weeks to arrive at your door (usually closer to a week).

Sometimes delivery can take longer, if our manufacturers are out of stock, for example, but this is unusual - we let customers know as soon as possible if something like this happens.

How do you ship my orders?

We use New Zealand Post and CourierPost to ship orders. Our default is courier, though you may organise an alternative with us by contacting us directly. CourierPost aims for next day delivery nationwide between major towns and cities in the North Island. South Island delivery can take two days. If you require next-day delivery in South Island, choose the express shipping option for the South Island. If you spend over $250 get your shipping for free!

When you buy something from us, the price is literally exactly what it says on the tin.

If you buy something from an overseas supplier, that is most definitely not the case. While the product might seem like a great deal on screen, it's important to understand customs and import costs.

In addition to the ticket price on an overseas purchase, whatever the exchange rate is on the day (this can fluctuate wildly - trust us, we know), there are also tariffs, GST and border processing fees. This can easily add upwards of 25% to the ticket price. Items costing over NZ$1000 also incur import entry transaction fees.

In addition to these extra costs, Customs clearance can also cause delays. Sea Tech has been importing for years - we've got this down to a fine art, and we've built relationships with customs that help our items clear quickly.

By buying from Sea Tech, you avoid all the headaches, delays and extra costs. We handle all this stuff for you, so you don't even have to think about it.

Want to know more?

These Nauticam housings are non-returnable, non-refundable, non-cancellable, and may be subject to extended lead times as they are manufactured on demand. We always do our best to meet trip deadlines so please advise us if you have a trip coming up!
