According to the manufacturer, the new housing provides “unfettered access” to all camera controls and functions, which enable a photographer to fully use the capabilities of the camera on dives. With durable construction and user-friendly features, the housing is “an ideal choice for underwater storytellers seeking a dependable and efficient underwater housing option,” states Nauticam.

The kit includes a camera mount to fit the a7R V and a modifier for the lock on the camera’s mode dial.

The $40 update kit is aimed at existing owners of the Sony a7 IV housing who are upgrading to the a7R V. As of January 2023, if you purchase Ikelite’s a7 IV housing, the camera mount and control modification for the a7R V are included in the box.

The housing for the Sony a1 is built around Isotta's B120 port system with 120mm bayonet, and comes with Isotta's classic features: anodized aluminium construction, integrated adjustable handles, double O-ring seals on buttons and removable parts, Isotta’s signature one-handed open/close, and a built-in moisture detector.

There’s a large-bore M28 port for attaching recorders/monitors such as the Atomos Ninja V or Ninja V+. The housing has two fibre-optic ports as standard with Nikonos N5 or S6 bulkheads as extra options.

The housing is compatible with the a7 Mark IV and the new a7R Mark V. Originally
designed for the a7 IV, a upgrade kit could be added to allow compatibility with the a7R V. Camera mount and control modifications are included in the box.

The original EOS R6 can also be accommodated in the housing with
the addition of a conversion kit (“provided upon request”, according to the manufacturer). In addittion to their new, higher-resolution 24.2MP sensor, the EOS R6 II shoots 12fps
bursts with the mechanical shutter (40fps with the e-shutter) and records oversampled 4K/60p video from the full sensor width.
