Its gradation can be used to selectively darken an image from edge to edge.

This filter is constructed from Schott glass for clarity and color fidelity. A padded pouch is included for storage and transport.

Q: 3. 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.

Q: 4. How much does the filter weigh?

A: I don't have the means to weigh the filter directly. I does not weigh more than any other of the B&W filters in this particular mount. You can go to the manufacturer website for this exact product and ask the weight question. B&W Photo does not permit inserting outside links, so do a Google Search on Schneider Optics, once on the website, copy and paste the manufacturer's part number that B&H Photo includes, that will give you the specifics on this product. Then you will have links to ask the weight question of an associate. I hope this helps.

Q: 6. What's the weight of the filter Could it be used instead of the balancing ring needed for the X5S?(drone proposes).

A: Unfortunately we cannot weight any products here and the manufacturers do not provide the weight of lens filters. It may be best to ask your question on the drone Q&A itself, but we would guess that it is the same weight and could be used as a balancing ring if necessary--though it is not an exact measurement.

Q: 7. Am I right to assume that a 58mm lens cap would fit over this filter?

A: Yes, technically a 58mm lens cap should fit. But filters like these can be wider. They essentially are made up of two polarizing filters sandwiched together. So they can be a bit wider because of that.
