Review: As a hobbyist this filter suited my needs perfectly, giving me the option to explore different photo and video opportunities with my camera, such as long exposures and slower shutter speeds for more natural video. It may be at the cheaper end of the market, but it's well made and does the job perfectly. Highly recommended.

Review: I've owned and used this filter for a few months now and it's OK for the price; it does the job. The reason I give this 3 stars is due to a couple of small annoyances: - The markings on the filter ring are pointless, they do not appear to give any kind of accurate measure as to how many stops the filter is set to, so you have to do this by eye and using your camera's meter - On wide angle lenses, you get some bad vignetting with this filter, it's simply not wide/shallow enough to be completely hidden from the lens (on my 35mm camera, I get vignetting with a 21mm lens which amounts to roughly 16mm on a crop sensor camera) - as with all variable ND's, at the extreme end of the scale you will get strange patterns and uneven exposure. I suspect a more expensive filter may have something in place to stop you reaching this extreme along with accurate markings, although I have not used one so cannot say for sure If you're looking for a cheap variable ND this will do the job, just be careful how you use it
