The CZJ lenses have a few good ones in the bunch, but you need to remember that they're 'still photography' lenses. That said, there's plenty of 'still' lenses which work well for video production with certain limitations. Typically 'still' lenses are optimized for different requirements. Most often they breathe when focusing and almost always have aperture rings which click and are difficult to mount gears to for remote aperture control.
The CZJ 35mm f2.4 is probably my favourite. I haven't tried them all but I can say good things about this one. It's sharp, has a useful macro feature built in, it has reasonable bokeh and doesn't 'breathe' TOO much. The focus ring has a decent feel to it. 35mm on a 5D3 is a useful focal length. WIde open it looses some sharpness and has a little chromatic aberration.
They have good value compared to current CZ lenses.
