The Lensbaby Edge 80 Optic is an 80mm f/2.8-22 flat field optic with an adjustable 12-blade aperture. This optic is specifically designed to be used in conjunction with a Lensbaby lens body to give you a slice of sharp focus, surrounded by soft blur. The size of the in-focus region varies depending on the aperture and the location of it can be modified by the degree and direction of tilt. The selective focus effect produced is especially desirable for close-up photography, as this lens can focus as close as 17" / 43.2cm when fully extended.
This optic is composed of 5 multi-coated glass elements within 4 groups and the 12 rounded aperture blades produce an extremely smooth bokeh. It is compatible with the Lensbaby Composer Pro, Composer, Muse, Scout, and Control Freak lens bodies (Not compatible with the Composer with Tilt Transformer for Micro Four Thirds and Sony NEX cameras).
