Additionally, both camcorders come equipped with a built-in ND (neutral density) filter, enabling filmmakers to control light exposure creatively without compromising on depth of field.

The user interface of the GY-DV300 and GY-DV301 is designed with professionals in mind. The camcorders offer manual controls for focus, iris, and white balance, allowing users to have precise control over their shooting parameters. The ergonomic design ensures that the camcorders are comfortable to use over extended periods, with a range of customizable buttons and settings readily accessible.
