Marelux new Aquista 135D water contact wide angle lens is ready for shipping. This is the third lens in the Aquista line and the first dry mount lens not requiring a flat port. Depending on the camera lens being used the Aquista lens mounts direct to the extension ring required for that lens. With commonly used lenses like the Sony FE 28-60 & 28-70mm the Aquista 135D AOV is 130 degrees. With lenses like a 24-70mmm as you zoom in the lens will work out to 135 degrees (diagonally) at around 26/27MM. This new lens retails in the US For $2599.00. Go to the Optics section on the Marelux.co web site to download the lens compatibility charts.

That’s great compact looking news.

Looks like 2026 is the year in which the high-end underwater optics monopoly is finally broken up.

I took a quick glance at the Aquista 135D port chart and the Canon selection of lenses is still very limited.

„Must-have Candidates“ that I would love to see listed:

• Canon RF 20-50mm F4L IS USM PZ most important new candidate!

• Canon RF 24-105mm f4-7,1 IS STM (will need a zoom limiter, but Marelux RF15-30 STM zoom gear fits this lens)

• Canon EF 28-70mm f/3.5-4.5 II

  (the historically best Canon Zoom lens recommended for use with the Nauticam WACP-1, costs just approx $70 in the used market and needs a Canon RF-EF Adapter to work)

• Canon RF 24-50mm f4,5-6,3 IS (dismal lens, but the noobs love it, so MARELUX gotta list it for completeness; as it will very likely work)

• Canon RF 28-70mm F2.8 IS STM (very likely to work)

I am sure lenses will be added and removed as we get user feedback. For Sony I will be trying the 28 F/2, Rokinon 28-60 F2.8 and a few more.

I have sent your lens suggestions to the design team for consideration and they are in the process of additional lens testing.

Also be aware that adapter rings for Nauticam and Sea & Sea are ready to ship so that the Aquista 135D can be used with those housings. Adapters for subal , seacam , hugyfort and Isota will also be coming. These adapters also allow the use of many Marelux ports and extensions on the listed housing brands. For Nauticam I believe N120 will be coming first.

There will be an N100 adapter eventually?

Many Nauticam users are already using the N120 to N100 35.5 so it will be linked to demand for N100. I suspect it will come in N100 but no conformation at this time.
