I've been toying with the idea of buying a gradient filter for a long time, although I have to admit that prices around 150 have always put me off. In the end I decided on a K&F sales filter that was a lot cheaper and I really wouldn't be disappointed!

When you open the incoming package, you will find that the packaging is very high quality. The brand is very careful in presenting their products and the materials are of high quality. The filter holder and adapter ring are metal and the filter holder has a spongy area whose function is to seal with the filter without letting light through. Once the filter holder is attached, it is easy to move. crtsal 100x100 quality is very good, with highly polished edges. The filter holder has two slots for square filters, but the advantage is that the ring screwed on the lens can be screwed with another round filter, for example a polarizing filter. I think the picture is very good. As with the brand's round filter, the sharpness is not lost, the color cast did not catch my eye, anything that can be edited during development is appreciated. The ND1000 filter included in the kit enables long exposures in strong light. The sample photos are photos taken on a cloudy afternoon with and without a filter. Those with filters were made with an exposure time of 20 seconds.

The adapter rings allow us to place the filter holder on any lens as we have a large number of different diameters. They are made of black metal and are well made. Labeled on each ring with the appropriate diameter. The filter holder is metallic with the part where the filters go made of some sort of hard plastic. Two 100x100 filters and 100x150mm gradients fit easily. The system of attachment to the adapter ring is via a very manageable metal tab. In several tests that I carried out under different lighting conditions, I did not notice the entry of residual light through the space between the filter and the filter holder. The photos have a slight magenta tint which is very easy to correct when editing, but it's not exaggerated at all. I am very happy and enjoying it very much. I recommend it!

After looking at the competitors and trying brand names she found these at a fraction of the price without compromising on quality. The overall user experience from delivery is exceptional. You are very much buying a high end product without the overpriced name brand. I bought these to help with my landscape photography and they work exceptionally well with my Sony A7III. The camera practically sees at night so to get a long exposure without this filter was incredibly difficult, I would often have a very split image with the moon/sun being very bright at the top and everything under the sky being in total darkness. After using the occlusion filter, all additional adjustments were done on the fly. The material feels very sturdy although I don't plan to test the limits, I believe it's scratch resistant. Looking forward to sunsets to test this further.

All in all a good product. The quality of the glass filter (ND1000) looks good and can also be easily pushed into the holder. Everything is made of metal and makes a robust impression.
