Product Highlights

  • Enhanced Ball & Socket Selective Focus
  • 12-Blade Diaphragm Adjustable Aperture

  • Pre-Installed Sweet 35 Optic

The Lensbaby Composer Pro With Sweet 35 Optic for Pentax K is part of the Lensbaby series of SLR lenses, and offers the same spectacular special-effect results. However, the refined and enhanced Composer Pro gives you ultra-smooth focus and tilt control and will retain its position after being bent, which makes it easy to use even with one hand. Simply tilt the lens to a desired angle and then focus with a traditional barrel focusing ring.

The Sweet 35 Optic is a 35mm optic with a 12-blade diaphragm and adjustable aperture (f2.5-f/22) that gives you unprecedented precision control over your selective focus photos--just rotate the dial on the front of the optic to quickly change the size of your in-focus "sweet spot". This is the widest focal length of any Lensbaby selective focus optics--the Sweet 35 also has close-focus capabilities. The lens can be bent off-center in any direction for different results.

The Composer Pro is compatible with the Optic Swap System--a line of different "optics" that can be interchanged with the Muse and Composer versions. This provides artists with an almost unlimited variety of looks and styles to capture their unique visions.

The Composer Pro comes supplied with the Sweet 35 Optic.

No electronic communication is possible between the camera and the lens. All operation is strictly manual. Automatic light metering is possible by shooting in aperture priority mode for almost all digital and film SLR camera bodies.
12-blade diaphragm adjustable aperture.
High-quality optic with 4 multi-coated elements in 3 groups.
The Composer Pro features a unique manual focus design which requires more rotation to move the optic as you approach infinity. This makes it easier to focus on objects at intermediate and distant depths than regular manual focus lenses.

Focal Length 35mm
Filter Size 46mm
f/Stop Range f/2.5-f/22
Groups/Elements 4 multi-coated glass elements, in three groups
Diaphragm Blades 12-blade internal aperture, controlled by a dial on the front of the optic
Minimum Focus Distance 7.5" for Sweet 35 Optic used with Composer Pro

      Very well constructed. Nice to have a fully manual lens again. Helps me to slow down and think about the image I want to create. Love the selective focus ability and the smooth bokeh this lens creates.

        Comments about Lensbaby Composer Pro with Sweet 35 Optic for Pentax K:

        I have always been a lensbaby fan since I bought my first one almost 5 years ago. There is nothing you can do wrong taking photos with the Lensbaby, you bend it and shape the lens as it is on your DSL and then wow yourself at the results. When I saw that Lensbaby had included more speciality lenses I jumped at the chance to own them all. The Composer Pro with The Sweet 35 has met and exceeded all my expectations..This Composer Pro is part of the Swap System and I ordered even more lenses to put into the Pro...We are getting a blizzard tomorrow and I will be ready to aim, bend and shoot.
