Sigma sd Quattro H Review

February 6, 2017 | Mark Goldstein |

Image Quality

All of the sample images in this review were taken using the High JPEG setting, which gives an average image size of around 15Mb.

The Sigma sd Quattro H's image quality is outstanding when shooting in the RAW format, with great results from ISO 100-1600. Curiously the quality drops off noticeably when shooting JPEGs, with only ISO 100-400 worth using thanks to a lot of noise and colour desaturation at the higher ISOs, so our advice would be to always use the sd Quattro H's RAW mode if possible (despite the so-so Sigma Photo pro software and the huge file sizes). The night photograph was very good, with the maximum shutter speed of 30 seconds allowing you to capture enough light for the majority of after-dark situations.


There are 7 ISO settings available on the Sigma sd Quattro H for both JPEGs and RAW files. Here are some 100% crops which show the noise levels for each ISO setting, with JPEG on the left and RAW on the right:
