ARRI APO Cambrian ACP40IB-PL 40mm
Apochromatic optics in this 40mm T2.0 lens virtually eliminate chromatic aberration for edge-to-edge sharpness, while the constant aperture keeps illumination consistent. A robust all-metal build and smooth, geared focus ring enable precise manual pulls for cinema setups. It’s ideally suited for portrait shooters and indie filmmakers needing a clean, color-accurate image with reliable tactile control.
