Solid build, no color cast. Easy to attach other filter holders to, such as Lee adaptors. While this is simply intended as front element protection, I have no intent on testing!

This Sigma ceramic lens protector is superb. I've using this product a lot this past week, and no dust has shown up, it's clear as it could be. I am using the 77mm filter on my Nikon 80-400mm AF-S G Ed VR and my 24-70mm lenses. I thinking about getting a second one.

Four stars instead of 5 only due to the manufacturer's price point. Haven't put it to the test since purchasing this item as I try to be very careful with my gear. However in reading about the Ceramic Protector Filter as well as watching video produced by the manufacturer in my view it's likely...

Expensive, but no issues. One star off for being expensive.

Im not prepared to risk seriously expensive glass, for the sake of saving a few bucks on a protective filter that makes virtually no difference to image quality.SIGMAs ceramic filters offer the best protection. And I defy anyone to prove they make any difference to image quality.

I own several Sigma Ceramic WR filters from 67-82mm. All of them are great, and none of them have been scratched or otherwise damaged in any way. I have not noticed any issues with flare or other impacts on the image quality. They are resistant to getting smudged, and they are very easy to clean.

I'll start with a PS - one question further down is would I recommend this filter to a friend. Despite the obvious cost of it, I now have THREE of them. On my most expensive lenses. (The other lenses in my kit now have the benefit of my best UV filters.

The first dilemma is whether we really NEED a filter to protect our lenses. To reduce risk, I've always chosen the filter route. Yes, with modern digital a UV lens is probably unnecessary most of the time. And this isn't even a UV filter. In fact, it's not even a filter!
