Nauticam Announces Housing for Sony a7C II and a7CR
By DPG Editorial Staff, November 27, 2023 @ 07:30 AM (EST)

Nauticam has unveiled its housing for the a7C Mark II and a7CR, Sony’s latest compact full-frame mirrorless cameras. The a7C II has much in common with the a7 IV and is built around the same 33MP sensor, while the a7CR takes its inspiration from the a7R V, including its high-resolution 61MP sensor.

The NA-A7CII is built around the N100 port system, like Nauticam’s housings for the “full-size” a7 series, and features integrated handles, ergonomic control placement (including right-hand thumb lever for AF-ON), and the company’s vacuum check and leak detection system as standard.

The housing features a large-bore M24 bulkhead to support HDMI 2.0, allowing you to connect an Atomos Ninja V external recorder. Strobes can be triggered via fiber-optic cables with the addition of an optional LED flash trigger, while an electrical bulkhead is also available.

Shipping now from retailers such as Backscatter, the NA-A7CII costs $3,286.

The Nauticam NA-A7CII Underwater Housing

Nauticam is the industry leader in mirrorless interchangeable lens underwater camera support. Nauticam has housed more mirrorless cameras and more Sony E Mount cameras than any other housing manufacturer. This experience results in the most evolved housing line with the broadest range of accessories available today.

Pioneering optical accessories elevate performance to a new level. Magnifying viewfinders, the sharpest super macro accessory lenses ever made, and now the highest quality water contact wide angle lenses (the WWL-1 and WACP-1) combine with the NA-A7CII housing to form a complete imaging system.

Nauticam is known for ergonomics and an unmatched experience. Key controls are placed at the photographer’s fingertips. The housing and accessories are lightweight and easy to assemble. The camera drops in without any control presetting, and lens port changes are effortless.

NA-A7CII features an integrated handle system. This ergonomic style provides exceptional control access, even with thick gloves, with ideal placement of the shutter release and a thumb-lever to actuate the AF-ON button from the right handle.

Nauticam's build quality is well known by underwater photographers around the globe. The housing is machined from a solid block of aluminum, then hard anodized making it impervious to salt water corrosion. Marine-grade stainless and plastic parts complete the housing, and it is backed by a two-year warranty against manufacturing defects.

Fast and Reliable Flash Triggering

Reliable rapid-fire manual flash triggering is available with the NA-A7CII for a variety of optically fired flashes when used with the LED Flash Trigger (26302). The NA-A7CII comes fiber optic ready and accepts the Universal Fiber Optic Cable (26216).

Strobes and light arms can be attached to the housing via included 1″ accessory mounting balls.

Electrical strobe triggering is still an option for those with an investment in legacy lighting gear, requiring the purchase of an accessory electrical bulkhead (25056).
 


Integrated Vacuum Check and Leak Detection System

The Nauticam vacuum check and leak detection system is available with NA-A7CII as standard equipment. Combined with an optional vacuum valve (PN 25624), this monitoring system provides constant updates on the water-tight and safe-to-dive status of the housing. A simple coded LED lighting system lets the user know that the vacuum is solid, or that the housing is losing vacuum. Leak detection is built into the same circuit, so if there is water intrusion, an audible and visual indication will occur.
