The Lensbaby 2.0 SLR lens is the slightly more refined descendant of the Original Lensbaby, featuring a sharper optic, a new f/2 aperture setting, and magnetically levitating aperture disks. Lensbaby 2.0 features a low dispersion, high refractive index, multi-coated optical glass doublet which is capable of delivering images with a tack sharp sweet spot of focus with minimal diffusion even at the f/2 aperture setting.
