Tiffen 58mm 4 Point 2mm Star Filter with Case - See pics.  

Wedding photographers will especially appreciate the value of this filter. When it comes to special effects shots, why not offer your client a table shot of the menu or invitation next to a glowing, star-filled candle? Shooting at night? Make that street lamp take on a different, more dramatic appearance by using the star filter. Any point light source will achieve the effect.

Tiffen's ColorCore glass is produced through a process that entails permanently laminating the filter material in between two pieces of optical glass that are ground flat to tolerances of a ten-thousandth of an inch, then mounting them in precision aluminum rings.
