Anode Alert

Do you have a Nauticam housing made of machined aluminium? Have you had it a while? Have you noticed the anodes? Are they still there?!

What's an anode?

Anodes, or sacrificial anodes, are highly active metals that are used to prevent a less active material surface from corroding. (On your Nauticam housing, the anodes are zinc.) Sacrificial Anodes are created from a metal alloy with a more negative electrochemical potential than the other metal it protects. The sacrificial anode will be consumed in place of the metal it is protecting, which is why it is referred to as a "sacrificial" anode.

Located on the bottom of your housing, anodes prevent your housing from being slowly consumed by the water you're diving in. They're a very small but very vital part of your housing. They should be replaced once 50% of the anode is remaining.

New! Sony RX100 Mark VII!

On the surface, the Sony RX100 VII looks the same as the previous iteration. It features the same 24-200mm f/2.8-f/4.5 zoom lens, the same pop-up electronic viewfinder, the same flip-up touchscreen, and the same battery. What makes the Mark VII special is the new image sensor at its core, and the focus and speed performance it promises.

The “newly-developed” 20.1MP 1.0-inch stacked CMOS sensor with DRAM chip built in promises Sony a9 levels of autofocus speed performance. This means a combination of 357 phase-detect and 425 contrast-detect autofocus points, the addition of Real-time Tracking and Real-time Eye AF for both humans and animals, up to 60 AF/AE calculations per second, and blackout-free 20fps bursts with full AF/AE tracking.

We don't yet know if it's going to fit the existing housings, though we expect it will. If you want to be kept up to date, then contact us and we can fill you in as soon as we have the details. Coming August.

New! Canon G7 X III!

Early reviews suggest the physical design of the Mark III is the same as its predecessor, though it's a bit lighter. While the lens remains the same as before (24-100mm equiv. F1.8-2.8), the camera has an all-new sensor: a 1" 20MP Stacked CMOS, which up until now was a Sony exclusive. Powered by Canon's Digic 8 processor, the G7 X Mark III can shoot raws at a blazing 30 fps with AE/AF locked, though the burst rate drops down to 8.3 fps if you want continuous AF.

The PowerShot G7 X III features live-streaming to YouTubecapability via a wireless connection, vertical video support, 4K up to 30P high-rate movie with no crop, full HD up to 120p, and an optical 4.2x lens.

A lot of Canon's marketing is focused on the live-streaming capabilities of the camera, which are not really a huge thing for underwater photographers "in the field" as it were.

As above, we don't yet know if it's going to fit the existing housings, though we expect it will. If you want to be kept up to date, then contact us and we can fill you in as soon as we have the details. Coming August.
