Specifically designed to produce creative selective focus effects, the Composer Pro II with Edge 35 Optic from Lensbaby pairs the 35mm f/3.5 optic with a lens body for Canon RF-mount cameras. The Edge 35 features a flat field design for sharp, accurate rendering and its unique optical design also enables producing a dramatic slice of focus surrounded by a smooth, blurred border. When coupled with the Composer Pro II, this slice of focus can be moved and rotated within the image area, and changed in dimension, using up to 15° of tilt on the lens body. The optic also features a manual aperture for adjusting the width of the in-focus area and has an eight-blade diaphragm to further contribute to a smooth bokeh quality in the out-of-focus regions. The lens is constructed with nine glass elements in six groups, and each of the elements is multi-coated to resist flare and ghosting for high contrast, color-accurate imagery.
