Blender Market - Lens Sim:
Lens Sim is a Blender addon designed to simulate real-world camera lenses, enhancing renders with organic, film-like imperfections such as chromatic aberration, vignetting, distortion, focus breathing, and natural bokeh. Seamlessly integrated with Blender’s camera and Cycles rendering engine, users can extend standard cameras, access real-world optical effects based on actual lens data, and create custom lenses for unique visual styles. Features include precise depth of field, customizable aperture shapes, anamorphic effects, lens dirt for cinematic realism, and compatibility with render farms.
