Lensbaby optic with linear focus plane – tilt-shift-like effect in the Composer system. For miniature look, selective focus along a line, and creative focus control.
What is the Lensbaby Edge?
The Lensbaby Edge is an Optic series for the Composer system that creates a linear plane of focus instead of a sweet spot. It functions similarly to a tilt-shift lens – focus follows a line positioned by tilting. Ideal for miniature effects and controlled selective focus.
