The Optic Swap Founder's Collection is made up of the lens body and optics most used by Lensbaby Founder, Craig Strong. The Collection includes a Composer Pro II with Sweet 35, Sweet 50, Edge 35 and Edge 50 optics. This Collection comes in a custom-fit Small Optic Swap System Case with a heavyweight Lensbaby lens cloth. Sweet optics highlight your subject in a sharp sweet spot of focus surrounded by dreamy blur. Edge optics create an edge-to-edge slice of focus effect in any direction, enveloped in smooth, gradually increasing blur.
