Thank you for purchasing and using our products.
We are pleased to announce that new firmware for the SIGMA sd Quattro and SIGMA sd Quattro H is available for download.
Benefits of the firmware update;
【SIGMA sd Quattro (Ver.1.07) / SIGMA sd Quattro H (Ver.1.03）】
・It has corrected the phenomenon that it does not display lens names properly or images with accurate brightness in some image processing software. This is due to errors with the lens profiles recorded in the images.
・It has corrected the phenomenon that the cameras do not synchronize properly when the ELECTRONIC FLASH EF-610 DG SUPER SA-STTL is attached and the shutter speed is faster than the fixed synchronization speed selected in the FP Flash mode.
Please download the firmware from the following Download page
