K&F Concept Reverse Graduated ND8 Filters, Square GND8 Grad Neutral Density Filter 3-Stops 100 * 150 * 2mm Square Filter Optical Glass GND Slim HD Nano-Coating Waterproof

yes, it is a glass filter.I was a little concerned about durability, but the protective case provided is so well made, that after a few outings, I felt quite happy with it.Once in a bigger case, with my other resin filters, it can be carted about without worry.The actual filter properties can be a huge help with strategic sun blocking in landscape photography.A few practice runs soon had it behaving well.Recommended.

Lovely little addition to my filters, helps at those seascape sunrises, sunsets.Good quality coating, no colour cast or degrading in sharpness.Probability wouldn't have got a reverse grad if it was expensive but for this price is a no brainer.Packaging is very nice and feels like you got a high end product.It's my first K&F filter and I'm pleasantly surprised.

Far exceeds expectations. Quality of the packaging suits a much more expensive purchase. Visual quality ot the filter is equally first rate. Having used the filter in my filter holder I can see no evidence of colour cast or filter clarity issues. Overall I have only exceedingly good things to say about this supply. Will definitely be seeking out this manufacturer for future filter purchases.

It doesn't seems to be same quality glass as those comming directly from K&F Concept (lighter and thinner glass than other 150x100mm) which makes me feel it's not legit. Also it doesn't come in the same leather case with easy access stripe. Overall, it's a good filter with just a little colour cast that can be reduced in post processing. For this price (60£ cheaper than form K&F Conc web) it's a good buy if you'd like to start your adventure with long exposure photography.

Well presented lookswell made pouch is nice touch haven,t tryed it out yet for colour cast but for price i dont expect lee quality give one a try

Apalled at the price of Lee filters and holders I decided to try the K&F kit. The quality of manufacture and packaging feels top-notch and using the Reverse Grad ND filter for dawn landscapes I could find no adverse effects.

what you get for your money - optical glass (tougher than resin), no distortion, no colour cast = perfect filter!

Much better than the bulky lee filter holders. Filter seems to work well so far.
