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).
The Lensbaby Sweet 50 Optic is made for use with the Composer Pro, which can be bought separately, or used interchangeably with the Sweet 50 if you own it already with a different optic. It is a selective focus lens that uses a curved field of focus optic to create a blurred effect around the focus spot.
The 50mm focal length lens has two multi-coated glass elements in one group, and an aperture range of f/2.5 to f/22. The 12-blade internal aperture is easily controlled via a ring on the front of the optic. The sharp sweet spot of focus can be moved within the frame by tilting the Composer Pro's ball-and-socket joint. The size of the sweet spot is also controlled by changing the aperture.
