The Special Edition Spark 50mm f/2 Selective Focus Lens from Lensbaby for Canon EF mount cameras is a selective focus optic that produces images with a sweet spot of focus surrounded by blur. This limited edition lens has a faster aperture of f/2 compared to the Spark which has a maximum aperture of f/5.6. It also includes nine creative aperture discs, and three regular apertures of f/2.8, f/4, and f/5.6.
The creative aperture discs each have a different design that will appear in the bright points of light in the out-of-focus areas. They are held in place by shielded magnets.
