The Fixed Body with Sweet 50 Optic from Lensbaby is made for use with Pentax K cameras as 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 multicoated 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.
