Pixie Dust
Pentax shooters know all about pixie dust. For the uninitiated, a few specific Pentax lenses that are well-known for their almost magical ability to make even mundane subjects take on an ethereal visual quality are said to have pixie dust in them. I own a couple of them and when I use them I love being surprised when something that looks iffy through the viewfinder gets sprinkled with the pixie dust as it passes through the lens.
