CNC machined from a single piece of billet aluminium then anodized.

All buttons and hardware are marine grade 316 stainless steel, providing superior corrosion resistance.

Our aluminium construction is far superior to competitors polyurethane construction due it’s ability to absorb heat generated by the camera (which prevents overheating), and it’s fantastic strength to weight ratio (providing a super lightweight yet super strong housing).



Our housings are painted in a highly durable two-pack paint. The paint not only provides additional corrosion protection to your housing, but also provides an opportunity to customise the look of your housing.

You get to choose your colour(s)! And the options are almost endless.

You can choose a color from here, or from our Instagram page (@saltysurfhousings)

Our ɑ-PRO housing will ship with our MINI port system, designed for mirrorless lenses with an overall diameter up to 80mm. The MINI port system is very compact, yet is still compatible with lenses such as the Sony 16-35mm f4, and the Sony 70-200mm f4.

For those shooters looking to use the larger Sony G-Master lenses, such as the 85mm 1.4, 70-200mm 2.8 & 16-35mm 2.8, you can upgrade to our STANDARD port system. The STANDARD port system is of larger diameter than the MINI port system, and allows the fitment of these bulkier, G-Master lenses.

It is possible to switch between the two port systems by simply swapping the acrylic faceplate to the appropriate system, so you can choose to upgrade (or downgrade) in the future if required.

The front element in our ports is replaceable in less than 30 seconds by simply unscrewing the locking ring and dropping in a replacement acrylic screen we offer for purchase. So no more spending hours buffing scratched ports!
