Expand your creativity and create memorable images with the Fixed Body Soft Focus II 50 Optic from Lensbaby. Designed for Pentax K-mount digital cameras, this 50mm special-effect lens offers a 45° angle of view for full-frame image sensors. Featuring an aperture range of f/2.5 to f/22, this updated lens adds a 12-blade manually adjustable internal aperture to its unique and versatile drop-in magnetic aperture system. Opened up to its brighter aperture settings, the Soft Focus II 50 Optic creates dreamlike impressionistic images with a subdued color palette and a remarkably flat field of focus. Stopped down to f/8 or darker, the lens creates beautifully detailed and sharp images with a large central area of focus and out-of-focus edges on full-frame sensors.

Hello, Does this lens come with a pouch? If not, what size of pouch would you recommend? Thanks!
The Lensbaby Fixed Body Soft Focus II 50 Optic does not come with a case or pouch. The Pentax mount version is 3x3.19 inches so the OP/TECH USA Fold-Over Pouch #303 would be a good fit:
(BH #OPFOP303B • MFR #7801052).
