"The D850 for example has been problematic for many Sigma telephoto lenses"........
Plenty of complaints about lenses such as the 300mm F2.8 etc......on the forums!
It may not be the reason here...........nonetheless people are stating they upgraded the latest FW only to find one their Sigmas no longer focuses with the new FW.......
....... of course they may have been making it up!
