I am using a Sigma 150-600 C. I got it as a gift so I don't complain about any of its faults (BIF).
However, with the disappointment with the 7.1 end of the RF 100-500, I would be very surprised if Sigma was not working on native RF series lenses.
I have no idea if the new protocols the RF series uses are closely held proprietary info. Will Sigma have to reverse engineer the RF connection? If so, it could be a while before we see a Sigma RF 150-600 f/6.3.
