A lens for good staged scenes, if everything in the composition is set correctly, then this lens can produce a frame in a million. If you are trying to photograph in reportage mode, then there will not be much sense. To be honest, I still donβt understand why AF lives its own life, especially at f1.2. at a distance to the object of more than 2.5 meters, AF hits in 60% of cases, although there are no obvious signs of back and front focus. At close range, it almost always hits. PS If you think that you will buy this lens and mark 2\3\4 will produce masterpieces after each button press, then you are deeply mistaken. You need to know how to use this tool, and treat it with respect, and it will repay you with unique shots.
