I made that PDAF vs CAF game last night and this night, after seeing a nice movie, again. How can I say? In no case the LiveView AF gave me a less good sharpness and in about 80% it was clearly better than PDAF. I didn't use LiveView often, partly to save battery and the long delay between shutter button down and picture stored. That will change now.
'Course this makes me think. "If its' so easy to miss sharpness wide open with normal AF, no matter how much this fast lens costs, no matter how much time I spent with adjusting that thing and if the LiveView of a DSLR always will be a crippled mirrorless, then why bother?". One can say, what do you expect form a third party lens? Answer: Well, LV didn't care about genuine or Sigma lens, it just nailed the focus better. If I get in the mood I'll make a sample gallery. How about those nightshots, Dave - did you compare focus with PDAF and CAF?
