Don't waste time pulling a lens out of your bag or swapping optics with the Lensbaby Trio 28mm f/3.5 Lens. This pancake-style lens incorporates a rotating front mechanism allowing you to quickly select one of three different focus effects -Twist, Velvet, and Sweet- at a moment's notice. The Twist uses a Petzval-inspired design for a sharp center area surrounded by a swirl of twisty bokeh. Velvet has a dreamy central area with a soft focus look along with a soft glow. Sweet creates a sharp spot of focus in the center with a gradual fall-off to blur. All these can be carried without stuffing your bag with a variety of miscellaneous equipment.
