Specialty macro prime lens with 2x magnification for Canon RF mount.
The Laowa 85mm f/5.6 2X Ultra Macro APO is a 2:1 apochromatic macro lens for Canon RF full-frame cameras. 2X indicates 2:1 maximum magnification; APO = apochromatic correction for minimal chromatic aberration at macro distances. The 85mm focal length provides comfortable working distance at 2:1.
85mm focal length, f/5.6 maximum aperture, 2:1 maximum magnification, apochromatic correction (APO), Canon RF mount, manual focus only.
The combination of 2:1 magnification, apochromatic correction, and 85mm working distance makes this a specialist macro lens for scientific, nature, and technical photography requiring extreme detail. Apochromatic correction at 2× magnification reduces the colour fringing that makes non-APO macro lenses less useful for high-resolution digital capture.
Test 2:1 macro performance carefully — at this magnification depth of field is typically under 0.5mm requiring precise focus positioning or stacking equipment. Verify APO correction by checking for lateral chromatic aberration in test shots. Inspect elements for haze. Confirm Canon RF mount engagement.
