Specialty macro lens with 2x magnification for Canon RF mirrorless cameras.
The Laowa 65mm f/2.8 2X Ultra Macro is a purpose-designed 2:1 maximum magnification macro lens for Canon RF APS-C cameras, part of Venus Optics' (Laowa) Ultra Macro series. 2× magnification produces a 2:1 subject-to-sensor reproduction ratio — the image on the sensor is twice the actual subject size, enabling extreme close-up detail capture beyond standard 1:1 macro.
65mm focal length, f/2.8 maximum aperture, 2:1 maximum magnification (2× life size), Canon RF mount (APS-C intended), manual focus only.
The 2× macro capability is the primary differentiator — standard macro lenses are limited to 1:1, making this lens suitable for extreme close-up photography of insects, circuit board details, watch components, and biological specimens. At 2:1 on APS-C the depth of field is extremely thin, requiring very precise focus positioning or focus stacking.
Test 2:1 macro focus accuracy. Check close-focus and standard focus operation. Inspect elements for haze or coating damage. Confirm Canon RF mount engagement. At 2× magnification, depth of field is less than 1mm at typical apertures — focus stacking equipment is recommended for sharp macro subjects.
