I shot a non-profit Dinner Banquet Friday night, and a high end Handbag charity auction Saturday night using the Rokinon 85 1.4, Sigma 40 1.4, and Sigma 24 1.4. All 3 lenses are new to me and I specifically chose to use only those on two A7iii bodies both nights.
Of course the Sigma 40 is phenomenal and a beast, but I was absolutely shocked by the Rokinon 85 1.4 sharpness. I can peep at shots from it and the Sigma 40 back to back and they compare to each other.
Only problem i've ran into is I noticed a tendency in low light using AF-C burst, and tracking, and touch of Godox fill flash that the first shots would be razor sharp, then following shots would be increasingly out of focus. Sometimes would snap back, and others would not. However, I also noticed this same tendency with the Sigma 40 1.4 though to a lesser degree.
However, I also updated both my A7iii bodies to the newest firmware Thurs night and didn't touch my existing settings at all, so I very well could need to tweak my tracking settings. I rely on AF-C and tracking almost exclusively for my event style shooting. Almost all of the shooting was at 1.4, thru 2.2, which is consistent to how I normally shoot.
Previously I would be using Sony 55 1.8 & 85 1.8, or Tamron 28-75 2.8 & Sony 70-200 2.8.
Unfortunately I didn't have the opportunity to switch from the new primes to the only primes to see if the focus tracking creep continued with my known lenses.
Intend to recreate some of the situations this week and see if I can recreate the focus creep on burst of 4-5 shots issue.
