Great piece for landscape photography. Variable ND without "shadow cross", clean in both areas. The polarizing filter works great, and if it gets too bright you'll love the ND, stepless control. Used on FZ200.

This was one of the best purchases I've made in recent times and I have no hesitation in recommending it, particularly to travel photographers who advocate carrying as little camera gear as possible. Filters are one of the accessory sets that I always carry with me as they are essential to 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 filters, with the exception of the circular polarizing filter, are made of aluminum alloy. Despite being very slim in design, they sure feel rigid without really flexing even when forced. The glass itself on all filters is coated optical glass (to reduce reflections) that is waterproof and scratch resistant. Overall, all 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 top left corner, but this is minor enough to be easily removed in post-production, as you can already see in my images. The ND filter worked very well with no color cast or vignetting. An undesired X effect does not occur. In summary, the image quality is excellent and the added benefit of using just one filter and adjusting the gradient without having to stack filters is really useful. Overall the look, feel and performance of these filters are top notch, but they are also affordable.
