The 10-stop, 46mm Heliopan ND Filter provides a 10-stop exposure reduction. Its 3.0 optical 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: 9. Is there a pan handle mountable zoom control that can be used with this lens?

A: The DZOFilm DZO 10-24mm T2.9 MFT Parfocal Cine Lens is a manually controlled lens and would require a motorized solution for zooming. The Tilta Nano II could be used to control Zoom, focus, and Iris if you add more motors. It could also attach to many items with its NATO Mount. You would also require 15mm rods or a rig with a rod to work with this solution. Tilta Nucleus Nano II FIZ Wireless Lens Control System BH #TIWLCT05
