Camera Overview — Sigma Quattro H

The Sigma sd Quattro H is a mirrorless camera built around an APS-H sensor delivering a 45MP resolution output, processed through a Dual TRUE III image processor. It captures stills at a maximum resolution of 6200x4152 pixels and supports a burst rate of 3.8fps, making it suitable for deliberate, quality-focused shooting rather than high-speed action work. The ISO range runs from 100 to 6400, keeping the camera in controlled or well-lit environments for optimal results.

Autofocus is handled by a contrast detection system with 9 focus points — a functional but modest setup that rewards methodical shooters. The camera is housed in a magnesium alloy body with dust resistant protection, measuring 147 x 95 x 91mm and weighing 625g. Imaging output is supported by a 3.0-inch LCD at 1.62M dots and an electronic viewfinder at 2.36M dots with a 60fps refresh rate.

Video capability tops out at 1080p at 30fps in 8-bit, with frame rate options of 24fps and 30fps. The camera uses the Sigma SA lens mount and accepts SD, SDHC, and SDXC storage media. Connectivity includes USB, Mini HDMI output, and a 3.5mm microphone jack.

There is no built-in image stabilization of any kind.
