I chose this filter to experiment with a creative effect directly during the shooting phase, without having to resort to digital solutions in post-production. The idea was to achieve controllable starbursts—specifically six-pointed star lines—especially when dealing with intense highlights or direct reflections.

The aluminum alloy frame feels solid, featuring a smooth rotation mechanism that allows for seamless adjustment of the six-pointed lines' orientation. The threading is precise and screws onto the lens correctly, with no lateral play. The AGC glass is crystal clear and introduces no noticeable color casts into illuminated scenes.

The star lines are sharp and relatively short—a characteristic I find pleasing, as it doesn't overpower the image. Upon closer inspection, the rendering varies significantly depending on the intensity of the light source and the distance of the light point. The multi-coating technology helps reduce unwanted reflections and flare, although I imagine that in certain situations involving very strong lights, some secondary reflections might still appear.

In practical terms, the ability to rotate the filter 360° allows for immediate and rapid customization: a simple twist is all it takes to alter the orientation of the star points. The resulting creative control is responsive, and I must admit that this gives me a pleasant sense of compositional freedom.

It is lightweight and easy to carry along, even in bags that are already full. The glass appears to be well-treated, showing no halos or visible imperfections. I cannot say how well it will withstand minor scratches over the long term—especially since an artistic filter like this is often handled more frequently than a standard one.

Essentially, this is an accessory that adds character without going overboard. The final result depends heavily on the specific scene, but the filter's general behavior is controllable and intuitive—something that is always useful when working with creative effects.
