Optical Filter SEAGULL GWIAZDKA 8x 40.5mm — screw-in filter for lenses

The SEAGULL GWIAZDKA 8x 40.5mm optical filter is a screw-in lens accessory designed for cameras with lenses that accept 40.5 mm filter threads. This 8x variant produces a starburst effect by creating multiple light rays from bright point sources, while also serving as a protective element for the front of the lens. Constructed to mount directly into a 40.5 mm screw thread, the filter provides a straightforward way to add controlled light-diffraction effects to night, cityscape, and creative portrait photography without changing the native focal characteristics of the lens.

Advantages

The filter delivers a consistent 8-ray starburst pattern around bright highlights, helping photographers introduce stylized flare and sparkle effects. Its screw-in design ensures stable, centered placement and reliable mechanical connection to compatible lenses. As a front-element accessory, it offers basic physical protection against dust and minor contact while remaining compact and lightweight for easy transport and everyday use.

Suitable for

• Night and cityscape photography to emphasize lights and highlights
• Portraits and wedding photography where controlled starburst effects are desired
• Creative and experimental photography to add sparkle and flare
• Any lens with a 40.5 mm screw-in filter thread for simple attachment

How to use

Attach the SEAGULL GWIAZDKA 8x 40.5mm by carefully screwing it into the lens’s front filter thread until it is snug but not overtightened. Compose and focus as usual; the filter creates the starburst effect primarily on strong point light sources or specular highlights in the frame. For maximum visible effect, shoot at smaller apertures and include bright, defined light points in the scene. Remove the filter when the starburst effect is not required to restore the lens’s original rendering.

Usage recommendations

Clean the filter surface gently with a microfiber cloth before use to avoid image degradation from dust or smudges. Use caution when mounting or removing the filter to prevent cross-threading; if resistance is felt, realign the threads before continuing. Store the filter in a protective case when not in use to maintain optical clarity.
