Lomography Petzval 27mm f/1.7 Review: Swirl Has Its Limits

The swirl is real. The 27mm focal length makes the Petzval effect genuinely usable for environmental portraiture without needing to step back to the moon. But a month of shooting surfaces what Lomography's marketing skips: wide open sharpness at the centre is softer than the f/1.7 spec implies it should be, and anything outside the sweet spot deteriorates fast. For a novelty lens you pull out twice a year for a specific brief, that's fine. For a working photographer hoping to use this as an actual fast prime with bonus character, it'll frustrate you. The Petzval series earns its place as a style tool, not a workhorse.
