Therefore, a wide angle lens is not the best choice for working with these filters over the full range.

The surface is fairly even, despite uneven lighting. Any value can be used. 180mm focal lenght - telephoto lens. The telephoto lens got the best results, although they are somewhat similar to the test at 50mm, but at 180mm everything is fine, fairly even fields, all steps are working and can be safely used in practice. The filter fulfills the declared characteristics. The color has remained practically unchanged, although in comparison you can catch a barely noticeable warm shade. In my opinion, acceptable and completely negligible. The adjustment ring is marked at regular intervals, BUT they do not inform how many steps the aperture is changed.

And we see that the first 5 steps came out quite smoothly, but after the fifth step, a noticeable drop and X-cross-effect is obtained, which is difficult to remove even in the editor.
