This was one of the best purchases I've made recently and I have no hesitation in recommending it, especially to travel photographers who advocate taking as little camera gear as possible. Filters are one of the accessory sets I always have with me, as they are essential for my landscape photography.

My first impression of the filters was the beautiful packaging they arrive in. They come in a hard cardboard box, with the filter itself housed in a hard plastic sleeve inside the box. The frames of all the filters, with the exception of the circular polarizing filter, are made of aluminum alloy. Although very slim in design, they certainly feel rigid without really bending, even when forced.

The glass itself on all filters is coated optical glass (to reduce reflections), which is waterproof and scratch resistant. Overall, all of the filters performed very well.

With the CPL, you can see a boost in the blue in the sky. There is a very slight vignette in the upper left corner, but it is so slight that it can be easily removed in post-production, as you can already see in my images.

The ND filter worked very well, with no color casts or vignetting. There is no unwanted X effect.

In summary, the image quality is excellent and the added benefit of using only one filter and adjusting the gradient without having to stack filters is really useful. Overall, the see, feel and last these filters are top notch, but are also affordable.
