Being able to selectively control the focus in your photographs down to one specific object or person is ideal for creative and advertising photography. The Lens Baby 3G Special Effects Lens allows for this to happen. You simply select your image and you lock in the sweet spot of focus with a combination of fine focus adjustments. There are also wide angle and zoom attachments. Remember to order the lens with the correct attachment to fit your particular DSLR such as Nikon’s F-mount or Canon’s EF mount. The minimum focus distance is 12 inches.
