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, which offers a normal perspective on full-frame cameras. 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.

  • Composer Pro II features an upgraded metal body with charcoal gray accents and an improved tilt control from 0-15° in any direction.
  • Compatible with Lensbaby Optic Swap System.
  • The Sweet 50 Optic is a curved field of focus optic that creates a spot of focus surrounded by blur when utilized with tilt. When used straight ahead, the optic functions as a normal lens.
  • Aperture range from f/2.5 to 22.
  • By using built-in close focus function, the Sweet 50 Optic can focus as close as 15" from the subject.
  • Lens construction features two multi-coated glass elements in 1 group.
  • The Sweet 50 Optic accepts 46mm filters for additional creative shooting techniques.
  • Internal 12-blade aperture diaphragm for smooth out-of-focus elements.

    Composer Pro II with Sweet 50 Optic for Pentax K is rated 4.0 out of 5 by 1.
    Rated 4 out of 5 by from Well made but it's a learning curve to use it properly Well made item, solid, not loose and floppy, can be tightened to work at the appropriate angle easily. Focusing is manual on my camera (Pentax K) and that presents challenges to use it properly. In fact, I've switched to my Fuji X-E2 (using a Pentax-to-X adaptor - which works well with this lens) because it is easier to achieve sharp focus using focus assist. Nevertheless, it is difficult to achieve good results with this lens and it will take a lot of practice. That's not a bad thing, and not a failing of the lens, just a failing of the user ! Anyway, if I want to point and shoot I can use my i-Phone :-) Focusing is achieved by turning the front silver ring . Very positive grip and feel. The advantage of this lens is that you can vary the strength of the effect by varying the f-number to f/2.5, rotating an aperture ring on the lens. That gets fiddly to use, especially when focusing moves the lens barrel down into the lensbaby, but doesn't make it impossible to use because the front of the aperture ring is knurled. Practice will improve this experience, I am sure. (Ideally, the aperture control should have a short rod or lever attached to it, so you can adjust it more easily as you look through the viewfinder, but that's not usually supplied on any lens, anyway.) The 50 mm lens is a little long for subjects that would likely benefit most from what this lens achieves, which is probably why they offer the 35 mm optic as well. The lens can be bought separately and swapped with the 50 mm, so that is good, flexible design.� The lens itself has a 42mm filter thread, so I may just attach a wide-angle adaptor lens to the front (it looks sturdy enough to handle this adaptation) because I don't need very high quality optics for the effects I am trying to achieve. In short, it's well made, will take a lot of practice, but gives you the opportunity to be creative in the moment. Getting focus just right is tricky because of manual focusing, but this keeps the user in control of the whole creative process. It makes for a pleasant creative experience compared with the usual, point, autofocus, shoot experience that we have with conventional lenses.
