CNC machined from billet aluminium then anodised and painted.

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

The A-PROX housing is designed to be more ‘production-friendly’ than our other Sony housings, with quick release clips and a M16x1 bulkhead for HDMI output for directors monitoring.

The housing also features new internal heat sinks.


The housing is compatible with our pistol grips, and dual handle video grip.




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)

The A-PROX housing comes with  our ‘S-System’ port system, which is compatible with lenses up to 105mm diameter.

BASE price does NOT include a mandatory port option. You cannot use the housing without at least one port.

The A-PROX housing does not allow fitment of larger CINE lenses due to the compact size of the housing.

SALTY DSMC2/KOMODO/BM housing owners note: all your current ports for EF lenses will work with the Wave housing.

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!




Shell only = approx. 1.5kg
