The Lensbaby Composer Pro II with Edge 80 Optic is an 80mm F2.8 tilt lens with a swappable optic that delivers the signature Lensbaby ""sweet spot"" effect - a tack-sharp focus on the subject with a streaky bokeh surrounding. The lens is ideal for portrait photographers and creatives wanting to work with selective focus at a longer focal length, but can be tailored to a range of different photographic disciplines. The curved field optic design allows precise manual control over the composition; whereas, the ""sweet spot"" focus effect can be moved around the image by tilting the unique, swivelling lens body. The lens is made up of four high-quality, multi-coated lens elements that are arranged into two groups, and there's a 12-blade aperture diaphragm that offers smooth and soft bokeh.
