Viltrox's ultra-fast wide-angle for Sony APS-C — the AF 27mm f/1.2 Pro with premium optics.
The Viltrox AF 27mm f/1.2 Pro is a fast autofocus prime from Viltrox for Sony E-mount APS-C mirrorless cameras, providing a 40mm full-frame equivalent field of view. The Pro designation indicates Viltrox's higher-tier optical formula with improved construction and coating quality over their standard range.
The lens delivers 27mm (40mm equivalent on APS-C) at f/1.2 maximum aperture with a linear autofocus motor for fast, quiet operation, full Sony E-mount electronic communication for autofocus, EXIF, and lens correction profiles, weather-resistant construction, and an APS-C-optimised image circle.
The 40mm equivalent focal length is a versatile moderate-wide perspective suited to street, documentary, and environmental portrait photography. The f/1.2 maximum aperture provides strong subject isolation and low-light capability for an APS-C lens. Viltrox positions this as an affordable alternative to Sony's own E-mount APS-C primes at a significantly lower price point.
Verify linear motor autofocus speed and accuracy on a compatible Sony APS-C body. Test sharpness at f/1.2, checking both central and edge performance across the APS-C image circle. Confirm Sony in-camera correction profiles apply correctly for distortion and vignetting. Check weather seal integrity.
