All MasterBuilt lenses incorporate a proprietary polishing method of the optical element. This process helps enhance signature flares and softer contrast reminiscent of the vintage Canon K35 optics. Each lens is engineered and assembled to the highest tolerances, ensuring accurate marks, zero backlash, smooth focus, zero* breathing, and solid build. The Masterbuilt Lenses perform to the highest levels of industry and mechanical standards. Each lens incorporates Aspherical elements which achieve superior aberration correction with less optical elements, ultimately producing higher quality imaging. The MasterBuilt lenses strike a balance of sharp images with soft edges. Optically the MasterBuilt Lenses have achieved significant characteristics, while maintaining clarity and precision.
