This 2-stop, 7.9 x 10.2" FotodioX Soft-Edge Graduated ND Filter is designed for use with the WonderPana 80 and FreeArc XL filter holder systems. It helps to darken specific areas of an image, such as bright skies, while allowing for a normal, unaffected exposure in the other regions of the image, making a useful filter for photographing landscapes with sky and and horizon. The filter is densest at the edge and tapers to clear by the middle, with a soft-edged line of transition between the dense and clear areas. A neutral density filter with a soft-edged line of transition is particularly useful for images that do not have a strongly defined transition between the sky and the foreground. Neutral density filters do not affect the coloration of the image and this filter provides up to a 2-stop reduction in light from entering a lens. This filter is made of durable, CR39 optical resin and measures 4mm thick. A carrying pouch is also included with the filter.

Q: 5. I have a vivitar 0.43x wide angle filter that accepts 62mm filter threads. I'm considering getting this Bower 62mm Variable ND filter and a 58-62 step up ring so I can use it on both the wide angle filter and my Canon G40's lens. My question is; would there be any amount of vignetting that would render the use of the ND filter on the wide angle filter pointless? How much of a vignette should I expect?

A: I can confirm what Roland said, this filter becomes unusable at its maximum/darkest setting. Roll it back just a bit and it's fine, but do keep that in mind.
