You could also get the Contax Planar 50/1.4 for video. It's about half the price of the ZE, I think, but very close in performance (slightly sharper in the center but a bit less sharp outside of it at wide apertures). You can also de-click the Contax (making changing the aperture completely silent), which isn't possible with the 50L.
The Contax has much less veiling haze wide open too.
