I chose this filter to experience a creative effect directly during shooting, without having to resort to digital solutions in post-production. The idea was to obtain controllable star lines, especially with intense points of light or direct reflections.

The aluminum alloy frame is solid, with a smooth rotation that allows you to adjust the orientation of the six-pointed lines without jerking. The thread is precise and screws properly onto the lens, without side play. AGC glass is clear and does not introduce obvious dominants into illuminated scenes.

The star lines are sharp and relatively short, a trait that I find pleasant because it does not dominate the image. On closer inspection, the yield varies greatly depending on the intensity of the light source and the distance of the light point. The multilayer technology helps to reduce unwanted reflections and flare, although I imagine that in some situations with very strong lights, some secondary reflection may still appear.

In concrete terms, the possibility of rotating the filter 360° allows immediate and quick customization: a gesture is enough to change the orientation of the tips. The resulting creative control is sensitive, and I must admit that this gives me a pleasant feeling of freedom of composition.

The weight is low and the filter is easy to carry even in already full bags. The glass is well treated; it has no visible pores or imperfections. I don't know how long it will withstand small scratches, also because an artistic filter is often handled more than usual.

In practice, it is an accessory that adds character without going to excess. The final rendering depends a lot on the scene, but the overall behavior is controllable and intuitive, which is always useful when working with creative effects.
