This 4-stop, 55mm Heliopan ND Filter is an ND filter with a 16x filter factor that provides a 4-stop exposure reduction. Its 1.2 density creates a darkening of the entire image, allowing you to photograph with a wider aperture or slower shutter speed without overexposing your image. By slowing your exposure time, you can create motion blur for special effects or to convey a sense of movement. Opening your iris allows you to create shallow depth of field, which can help isolate your subject. Neutral density filters do not affect the coloration of the image and are ideal for pairing with other filters.

To prevent internal ghosting and reflections, each glass surface includes four layers of anti-reflection coating. Together, these eight coatings offer greater protection to the filter substrate and help it to stay clean for longer than with uncoated filters. This Heliopan neutral density filter is constructed from Schott glass for increased optical clarity as well as color fidelity and features a brass filter ring for enhanced durability and jamming prevention.

Q: 6. Is the autofocus quiet enough to use while filming videos? (with a shotgun mic mounted on the camera)

A: Yes, the Sony Sonnar T* FE 55mm f/1.8 ZA Lens uses a linear stepper autofocus motor which is already very quiet and compatible for video recording usage needs. As you are using an external shotgun microphone which further increases the distance of the microphone from the lens, you should not have any issues with audio from the stepping focusing motor inside the lens.
