I have Viltrox 85mm f1.4 PRO...it's a great lens, but...have you noticed on 50mm that sometimes needs time to focus..when focus is on infinity, and you want to focus on something close that is not contrasty, it struggles a little bit? Other than that, it focuses quickly
I cannot reproduce that issue. The 50 seems very fast and accurate at acquiring focus. My 85 Pro should arrive today. I really like the form factor of the Pro series so looking forward to having both the 50 and 85 in this series.
