The current state of soft- and firmware

Sigma has been updating their software and firmware more often than this site has been updated. Therefore I thought it might be a good idea to list where we stand today.


Sigma Photo Pro is now at 6.3.2 for both Windows and OSX. Besides many bug fixes there have been substantial improvements in the processing engine. Especially the last update supports the vastly improved color reproduction of the dp Quattro series cameras with the latest firmware.

With the latest firmware update for the dp Quattro series cameras Sigma changed the color reproduction considerably. Skin tones are more pleasing, skies are more blue and contrasty and reds do not get saturated as fast as before. To see the differences in processing you can have a look at the following page:

The firmware is available for download at the following sites.

SIGMA dp0 Quattro cameras:

SIGMA dp1 Quattro cameras.

SIGMA dp2 Quattro cameras:

SIGMA dp3 Quattro cameras:

Notice: RAW data (X3F files) taken with the dp Quattro series cameras after the firmware update has been installed cannot be processed in software prior to SIGMA Photo Pro 6.3.2. Please use the latest SIGMA Photo Pro 6.3.2 to process for the latest RAW data.


  1. Thanks for the update; unfortunately, the big issue is still unresolved: the main reason why I had to ‘abandon’ Sigma cameras was/is that their raw files cannot be read in Lightroom, which is my main processing tool.
    I did try for a while to change my flow and convert from raw to tiff using Photo Pro and then process into LR and NIK’s, but it gets WAY too slow and cumbersome (especially with the humongous files the Merrills generate).
    Until the day it is possible to import X3F files directly into LR, I will have to stay away from Sigma cameras – which is a real shame, I absolutely love the images I used to get with the ones I had!
