Many of the shortcomings are due to its price and it’s not worth it to be indignant at all, an excellent lens for those who do not shoot constantly dynamic reports) Has some pros: -Really sharp! - normal stabilization - pretty compact -Wide FR change ring Got cons: -Very slow autofocus -dark (well, for such a price and so good) -plastic mount (again, the price) - sometimes there are problems with autofocus (at 200 mm it drives the lens close and gets stuck there, and makes a grinding sound)
