The Sigma sd Quattro H is a mirrorless, SLR-style interchangeable-lens camera featuring a 38.6-megapixel APS-H Foveon X3 sensor, Sigma SA mount, electronic viewfinder, and 3.0-inch TFT color LCD.
The camera is praised as Sigma's best model, offering exceptional detail due to its Foveon sensor. However, it is described as a highly specialized tool with significant limitations regarding noise and dynamic range, making it unsuitable for those seeking a fast or flexible all-purpose camera.
The review concludes that the camera is a stellar, specialized tool for landscape and studio photographers that offers medium-format-level image quality at a lower price. It notes that while the addition of DNG support improves the workflow, the camera remains limited by its poor high-ISO performance and slow responsiveness.
The reviewer describes the camera as a mixed bag that shows great potential for landscape, architectural, and studio work due to its beautiful colors and image quality. Ultimately, it is not recommended as a primary professional system because of its various quirks, flaws, and lack of versatility compared to competing options.
The review highlights the camera's unique sensor and ability to produce astonishingly crisp images. It suggests the camera should be considered by landscape, portrait, architectural, and lifestyle photographers while acknowledging that its specialized technology makes it a niche choice rather than a first option for everyone.
