At http://www.zebrafilm.com there is a Database page with all available Cine-lenses compiled.

A Unique collection of more than 800 lenses with details like minimum focus, weight, size etc.
The same Database is also used in the Filmcalculator Software / App for iPhone and Android devices.

Currently there are 3 screens with Lenses, Film-Stock and Lamps. They will be updated by the manufacturers themselves.
Soon there will be a Camera Format Database added for general use.
