16-55 is a great lens. Absolutely gorgeous and really does have a cinematic feel to it.
I am actually having some issues with the focus though, and most likely it is user error, I am flying mine on a gimbal and it locks and loses focus with the subject and hunts like crazy - yet handheld and tripod use is totally fine, and photo af is perfect, when im moving on a gimbal it freaks. most likely user error though
