Works perfectly. I haven't noticed any colour casting, nor does it appear to have any effect on the sharpness of the image. Perfect for long exposures to get that smooth, glass-like water effect. At this price, you really can't go wrong!

Is reasonably accurate as far as 10 stops is concerned. Only a slight difference in exposure between 30th and 30 seconds. Colour cast isn't too much of a problem, some trial and error will let you know how much to offset your wb for each light source. Biggest issue the excessive vignette this filter causes. I would not recommend this filter for that problem alone.

Don't see why I should spend over £100 for a 10 stopper of any of the big brands when this one does the job just fine! No unwanted tints or reduction in image quality that I can see (image attached is taken with this filter and any tints or hues are added in post production). Highly recommend!
