Excerpt: Paving the path for a technique known as “selective focus”, Lensbaby has been cranking out optic after optic focused — defocused might be a better way to describe it — on offering photographers a lens-based solution for creating dramatic photos. Niche? Maybe, but not the Lensbaby Edge 80 ($300) .

Pros: Quick aperture control, Good bokeh / background blur, Easy close-up mode, Quick and easy creative effects
Cons: Getting the Edge 80 out of the Composer can be fiddly, Quite high price if you don't already have a Composer
