I deliberately chose the K&F CONCEPT Starburst filter (6 points) in the 82mm version. This size offers maximum flexibility for adapting the filter to various lenses in my system using step-up rings.

Build Quality & Scope of Delivery: The filter comes in a sturdy plastic box, which serves as an adequate storage solution. In my case, three individually wrapped cleaning cloths were also included—a useful accessory. The filter thread is cleanly machined and screws onto the lens without any problems.

Practical Functionality: The key feature of this filter is its rotatable design for aligning the stars. On this model, the adjustment mechanism operates very smoothly and precisely. The rotational resistance is well-calibrated; it's easy enough for quick adjustments, yet firm enough to reliably hold the selected position. This allows for precise alignment of the 6-point stars, which is essential for targeted image composition.

Applications: As expected, the filter is excellent for night photography. Especially during the Christmas season at Christmas markets, it can create a stunning ambiance amidst the many strings of lights and other illuminations. But it also delivers the desired creative effect at concerts, in vehicle photography (headlights), or in product photography (specular highlights).

In conclusion: The K&F CONCEPT Starburst filter perfectly meets expectations. It produces a beautiful, clearly defined 6-point star, the axis of which can be precisely controlled thanks to the smooth rotating mechanism. A solid tool for creative lighting effects.
