Sigma sd Quattro-H

Overview of Sigma sd Quattro H

See Sigma dp0 and dp1 Quattro: Razor Sharp Detail—I shot the Sigma dp Quattro cameras with their APS-C sensor in fall of 2016 with some gorgeous results.

The about $1199 Sigma sd Quattro-H utilizes a relatively large APS-H 26.6 x 17.9 mm sensor (larger than APS-C and smaller than full frame), with a “crop factor” of about 1.38X versus full frame (36mm / 26.6mm), so that a 50mm lens has an equivalent field of view of about 69mm versus full frame based on those numbers; the EXIF info claims 66mm crop factor, implying a ration of 1.32X, which seems to be in error.
