This is definitely an amazing lens. I spent months researching high end 50mm lenses and settled on this one based on the specs and the 270 degree manual focus ring. That's because I mainly shoot with the BlackMagic Pocket Cinema 4K and the manual focus is flawless with this lens. The only thing that isn't perfect is the resistance on the focus ring. It's a bit too tight and introduces noticeable movement. I'm using tracking focus and you can see a little frame movement as you move back and forth to look for sharp focus.
