Along with its wider brother (MK 18-55 T2.9), Fujinon's 50-135 T2.9 cine zoom has just gorgeous image quality -- especially when paired with Sony's little a6300. The key is to truly lock the lens down on such a small body, and for that Zacuto's Scissors is fantastic: it locks the lens in place on your rail system by literally screwing into the lens itself, so you don't get flexing in either direction. If you have a Sony e-mount camera, you'll want to take a look at this pair. You may also want to look at the rig I used to hold it all together, the Sachtler Ace Baseplate; SmallRig 15 carbon fiber rods; Really Right Stuff L-bracket; and the edelkrone FocusOne.
