The 39mm Urth Soft Graduated ND8 Lens Filter 39mmfrom Urth Soft Graduated ND8 Lens Filter 39mmprovides 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: 5. I think I have seen some VND's have a total size larger than its threading part, which ends up blocking the ability to mount a lens hood. Does the size of this filter prevent the mounting of a lens hood?

A: Most Variable ND filters have a larger outer diameter than the thread in size. Urth ND2-400 (1-8.6 Stop) Variable ND Lens Filter (58mm) has a front and mount thread of 58mm. However, the outer diameter of this filter is 62mm therefore if your lens hood is not wide enough it may not fit with this filter mounted on your lens.
