Lensbaby Sony NEX Tilt Transformer When used with a Nikon mount lens, produces a slice of focus through the image Width of focus slice is dependent upon aperture - f/1.4 will produce a very thin slice of focus with abundant blur, while f/22 will produce a very wide slice of focus with just a tiny bit of blur. Extreme tilt at a very bright aperture will make that slice appear even thinner Tilts up to twice as far as standard tilt-shift lenses making it possible to achieve more extreme blur falling off of a very thin slice of selective focus, as compared to the usual slice of focus width and focus fall-off of a typical tilt-shift lens Built-in mechanism allows Nikon G lenses to function properly at all apertures. Nikon G lenses do not have an aperture ring on the lens itself. This mechanism allows the aperture to open and close by manually rotating the lens itself High quality metal swivel ball for smooth, fluid tilt
