Sigma 50mm 2.8 EX Canon tether
I tried to use this lens to tether Canon 5D Mark IV via CaptureOne. I can change all parameters but focus. Another lens (Canon 100mm 2.8 Macro) does everything.
So, camera is good, software either good or it is picky about lens. What do you think about Sigma lens on Canon - is it defective or not supported?
