Key Features

1. Weather-Sealed Construction

The HXR-NX70 is one of the few camcorders in its class with dust and rain-resistant sealing. Both the body and built-in microphone are designed to withstand outdoor conditions — making it ideal for remote locations, jungles, or unpredictable climates.

2. Back-Illuminated CMOS Sensor

The 1/2.88” Exmor R CMOS sensor allows for better light sensitivity and lower noise, especially in dim environments. It enables users to achieve professional results even without external lighting.

3. Professional Audio Capabilities

The camera includes a detachable handle unit with dual XLR inputs, manual audio level controls, and phantom power support. This allows for professional-grade audio capture using shotgun or lavalier microphones.

4. Dual Media Recording

With a 96 GB internal SSD and support for SD cards, you can simultaneously record to both or use relay recording for extended shoots. Internal SSD storage provides fast access and protection from media corruption due to shock or environmental conditions.

5. Optical SteadyShot with Active Mode

Sony's advanced image stabilization system compensates for camera shake, especially useful when filming handheld or while walking. Active Mode adds digital correction for even smoother footage.
