The 52mm Soft Graduated ND8 Lens Filter Plus+ from Urth provides 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: 7. I've never heard of magnalium. I always by brass rings because they don't bind like aluminum rings. How does magnalium compare?

A: Magnalium is an aluminum alloy with 10-5% magnesium and 90-95% aluminum. It is light, strong, and resists corrosion. In addition, the strength and hardness of aluminum increase when it is alloyed with such substances as magnesium, manganese, nickel, chromium, zinc, iron, copper, and silicon. Magnalium—lighter and more workable than aluminum—is used in making metal mirrors and scientific instruments. Since it is 90-90% aluminum, cross threading may still occur

Q: 8. is this filter appropriate for film cameras, or more importantly, will it work on a lens attached to a film camera?what's the advantage of the lens being non-coated?
