Here’s a compatibility tip regarding the Sigma SD1 Merrill and Windows 10. I have just upgraded to Windows 10 from version 8 and was initially horrified to find that my computer wouldn’t recognize the camera when attached by cable to the USB port as it use to do in version 8.

So, if you were worried about whether or not you could still use the camera with Windows 10, then here’s your answer. Sigma’s Photo Pro 5.5 software also works in Windows 10.
