The Lensbaby 3G SLR lens allows photographers to lock the Lensbaby in a desired bent position simply by pressing a button. Then, using a traditional barrel focus mechanism, photographers can do fine focusing and precisely place the sweet spot of sharp focus before pressing the shutter release.  The Original Lensbaby lens and the Lensbaby 2.0 lens require the photographer to manually hold the Lensbaby in a bent position while pressing the shutter release.   

Lensbaby selective focus SLR camera lenses take photos with one area in sharp focus, with that ‘sweet spot’ surrounded by graduated blur.  Photographers can move the sweet spot of sharp focus anywhere in the photo by bending the flexible lens tubing. 

Lensbaby 3G features the same low dispersion, high refractive index, multi-coated optical glass doublet and the same flexible tubing as Lensbaby 2.0, but adds three focusing rails that emerge from the camera mount and pass through the focusing collar.  A trigger button on the focusing collar releases three pins that engage the focusing rails and lock Lensbaby 3G in a bent position.
