Review (Summary): "By its very nature, this approach has made Lensbaby's products somewhat niche in appeal. But the company's latest optic, the Edge 80, may well see many more photographers sit up and take notice. It's an 80mm F2.8 telephoto lens that's optically-corrected across the whole frame, and designed to be used in the company's flexible lens bodies more-or-less like a conventional tilt lens. ...
... It offers much more flexibility than typical in-camera effects filters, which are commonly restricted to a sharp zone of fixed width across the center of the frame that often doesn't suit the subject. In contrast, with the Edge 80 you can vary the angle and width of the sharp region almost infinitely. ..."
