Lens Overview — Lensbaby 28mm f/3.5
Key Features — Lensbaby 28mm f/3.5
Three-Optic Rotating Wheel: A rotating front element switches between three distinct optic types — Sweet, Velvet, and Twist — each producing a different creative effect in-camera.
28mm APS-C Prime: The fixed 28mm focal length on an APS-C sensor provides a moderate wide angle suited to street photography, portraiture, and everyday creative work.
Sweet Optic Effect: Produces a sharp central focus point that blurs and vignettes toward the edges, creating a distinctive dreamy, soft-focus look.
Velvet Optic Effect: Renders images with a soft, glowing quality at wider apertures that transitions to sharper detail as the lens is stopped down.
Twist Optic Effect: Generates a swirling, painterly bokeh in out-of-focus areas reminiscent of vintage Petzval-style lenses.
Manual Focus Only: Fully manual focus operation suits the deliberate, creative shooting style that special-effect lenses naturally demand.
