Lensbaby Portrait Kit for Canon EF Mount Digital SLRs Ships with the Double Glass Optic installed and is compatible with all optics in the Lensbaby Optic Swap System. The Composers design is based on a ball and socket configuration that delivers smooth creative effects photography with ease. Soft Focus Optic is perfect for portraits. Images are overall soft and diffuse and are designed for a variety of soft focus applications. Photographers can control the degree of softness by changing the apertures. The Lensbaby Wide Angle / Telephoto Kit allows you to change your Lensbabys effective focal length to either 30mm or 80mm. The 0.6X wide angle converts the Lensbaby from a 50mm focal length to a 30mm focal length. The 1.6X telephoto converts the Lensbaby from a 50mm focal length to an 80mm focal length. The disks in the Creative Aperture Kit 2 have shapes cut out of them, and drop into the front of a Lensbaby lens just like regular Lensbaby aperture disks. The shape will appear anywhere bright points of light are out of focus in an image.
