The 58mm Urth Soft Graduated ND8 Lens Filter 58mmfrom Urth Soft Graduated ND8 Lens Filter 58mmprovides a fixed 3 f-stop light reduction from half your image for balanced exposure and better dynamic range in soft graduated light conditions. By blocking 3 f-stops of light from half the image, you can balance your exposure when the foreground is darker than the background - such as shooting landscapes in the mountains. The soft graduation creates a natural blending of light. The Plus+ range features 20-layers of nano-coating providing easier cleaning and better protection against water, oil, and scratches. These layers also provide a higher maximum light transmission and a more consistent transmission curve for truer light reduction.

Q: 1. Does it have hard stops?

A: The Urth ND2-400 (1-8.6 Stop) Variable ND Lens Filter (82mm) features smooth twist adjustments rather than hard stops for each stop. This allows for seamless and precise control over the amount of light reduction. The filter can be easily adjusted to achieve the desired exposure without any abrupt changes or limitations.

Q: 2. Is this filter coated?

A: According to the manufacturer, the Urth ND2-400 (1-8.6 Stop) Variable ND Lens Filter (58mm) features an 8-layer nano coating.

Q: 3. How many F-Stop is required to use with Rollei IR 400 film?

Q: 5. What is the glass used/origin and is it multicoated?

A: The Urth 77mm UV Lens Filter (Plus+) is made with SCHOTT glass and is multicoated.

Q: 6. Many variable neutral density filters either cause a color shift at darker settings or the dreaded "X-effect" on wide angle lenses. Does this filter suffer from those issues?

A: Any variable ND over 6-7 stops can create the X-effect. And that is the deign and physics of a variable ND filter. And it depends on the lens you are using and the light you are shooting under. As for the color shift almost all have some color shift including the Urth ND2-400 (1-8.6 Stop) Variable ND Lens Filter (77mm). These are higher models of filters, https://bhpho.to/3TSB4JH

Q: 7. Is this filter stackable? Can the lens cap still fit with this filter on?

A: Urth ND2-400 (1-8.6 Stop) Variable ND Lens Filter (67mm) has a front threaded diameter to attach 67mm lens caps and filters.

Q: 8. How many filters fit into the filter case?

A: All three filters fit into the case, however I keep the UV and the polarizing filters screwed on the lens.

Q: 9. Is it possible to use a lens cap with the filter?

A: Yes, the Urth UV + Circular Polarizing (CPL) Lens Filter Kit (82mm) has standard 82mm front threads for use with a standard 82mm lens cap.

Q: 10. is the front filter thread larger than the main filter thread?

A: The front of the filter will corresponds with the thread size of the lens. The Urth 77mm ND64-1000 Variable ND Lens Filter Plus+ (6 to 10 Stop) has a front thread of 77mm.
