JPEG images on the SIGMA sd Quattro
In order to optimize the image quality, we have been developing and updating the firmware for the SIGMA sd Quattro . For the SIGMA sd Quattro, from firmware Ver. 1.05 onward, improved noise reduction has been implemented to the image processing function. Although this specification benefits the overall image quality, under certain shooting conditions or depending on subjects, it may look like the resolution is lower than before. For such customers, we would like to offer a new option for the image processing that prioritizes the resolution power.
In order to change the image processing mode of JPEG files, please refer to the PDF file “How to change the image processing mode”. There is no change in the image quality of RAW data even when the image processing mode is changed. In addition, for those who change the image processing mode, the change will remain even after updating the firmware in the future.
