Our editorial take on the Sigma sd Quattro
The Sigma sd Quattro is a niche APS-C mirrorless camera built around the company's distinctive 29-megapixel Foveon X3 Quattro sensor, which stacks color layers vertically rather than using a traditional Bayer array. This approach delivers exceptional color accuracy and sharpness at base ISO, though the tradeoff is slower performance and limited high ISO capability. Reviewers consistently praise image quality below ISO 1600, noting improved noise handling compared to earlier Foveon models, and the camera's magnesium alloy build feels reassuringly solid.
The sd Quattro's quirks are significant. The Foveon sensor requires proprietary raw processing, the 3.6 fps burst rate and 9-point autofocus system trail modern competitors, and you're locked into the small Sigma SA lens ecosystem. The rear LCD is fixed, there's no wireless connectivity, and workflow can be sluggish. Still, for photographers who prioritize ultimate color fidelity and detail in controlled lighting over speed or versatility, the sensor's unique output justifies the compromises. This is a camera for deliberate shooting, not fast-paced action.
- Exceptional color accuracy and sharpness from unique Foveon sensor at base ISO
- Improved high ISO performance compared to previous Foveon models
- Solid magnesium alloy build with dust and splash resistance
- Super Fine Detail mode combines 7 exposures for maximum resolution
- Weak high ISO performance above ISO 1600
- Limited to proprietary Sigma SA lens mount
- Slow 3.6 fps burst rate and basic 9-point autofocus
- Fixed rear LCD with no wireless connectivity

Pros · Great image quality below ISO 1600 · Significantly improved high ISO image quality · Solid feeling body, perhaps the most solid feeling ...
The Sigma SD Quattro is an odd and interesting mirrorless digital camera with a seriously unique feature - a 29MP Foveon sensor.
