Laowa's ultra-fast APO wide prime for APS-C — 50mm equiv at f/0.95 with apochromatic correction.
The Laowa Argus 33mm f/0.95 CF APO is an ultra-fast prime for Fujifilm X-mount APS-C cameras, featuring carbon-fibre barrel construction (CF designation) and apochromatic correction (APO). Manual focus only. The f/0.95 aperture is among the fastest commercially available primes for the Fujifilm X system. Fujifilm X mount.
f/0.95 maximum aperture. 33mm focal length (approximately 50mm equivalent on APS-C). Carbon-fibre barrel (CF). APO (apochromatic) correction for reduced colour fringing. Manual focus only. Fujifilm X mount. At approximately 420g.
The apochromatic correction is notable at f/0.95: ultra-fast lenses commonly show significant longitudinal chromatic aberration (colour fringing around in-focus and out-of-focus transitions). The APO designation indicates Laowa has corrected this across multiple wavelengths, reducing the colour fringing that is typical of f/0.95 primes. The CF barrel reduces weight while maintaining rigidity.
On the used market the Laowa Argus 33mm f/0.95 CF APO Fujifilm X is an ultra-fast manual-focus prime for Fujifilm X cameras. Condition checks: Fujifilm X mount contacts (electronic coupling for EXIF and focus confirmation), focus ring smoothness across full travel, front element for marks, aperture blade smoothness at f/0.95. Manual focus only — no AF.
