Sigma customer service has always been second to none in my experience, but they upped the ante this week. On Wednesday I sent my 105mm back for a firmware upgrade to fix any issues with the D500. UPS just dropped it back at my house an hour ago. I'm one day away for shipping, so this means Sigma received it, updated it, and shipped it back in the same business day. They told me these things shouldn't take more than 48 hours, but this had to take less than 6.
I suspect this isn't typical, but it's pretty darn impressive.
