Sigma mc11 adapter question
First time posting on fstoppers and I hope to get the right and correct answers.
I first want to say that I am a deployed US service member that just switched from Canon to Sony and my life couldn't be better! I also purchased the mc11 adapter so I could put my L series glass onto my Sony so I wouldn't be having that glass go to waste. The major question that I am asking about is the usb cord that comes with the adapter... mine didnt come with one. I guess that might be why it was so cheap since it was an open box item. Now since I have the sigma dock at home, will that cable work on the adapter so I can update firmware for it?
Thank you all
