Draw more attention to your subject with a circular spot of focus surrounded by a beautifully blurred background by using the Lensbaby Composer Pro II with Sweet 50 Optic, available here with a Pentax K mount. This updated tool is completely compatible with the established Optic Swap System and can use any of the numerous optics available. This version improves upon the original Pro model by featuring a metal body as well as an improved tilt function that ranges from 0-15° in any direction. Bundled with it is the Sweet 50, offering a medium telephoto field of view on an APS-C camera, with a 35mm equivalent focal length of 75mm. This curved field optic differs from your standard lens by creating a spot of focus when tilted that can be manipulated in position by tilting the Composer and manipulated in size by manually changing the aperture from f/2.5 to 22. The optic also offers manual focus as close as 15" from your subject. Additionally, the Sweet 50 has a 46mm filter thread as well as an internal 12-blade diaphragm for extra smooth out-of-focus areas.
