Most anamorphic lenses, including Panavision's, have a 2X squeeze factor. This means that the area used on 35mm film or a digital camera will only end up being a 1.20 : 1 aspect ratio if it has a 2X optical squeeze, because unsqueezed it would be 2.40 : 1.
So out of a 16x9 (1.78 : 1) sensor, you'd be cropping it to a 1.20 : 1 area if you used a 2X anamorphic lenses.
The only anamorphic lenses designed to get you a 2.40 image on a 16x9 sensor are the new 1.33X Hawk anamorphics -- if you can find them and can afford them, that's great. (There is also the rare Canon 1.33X anamorphic rear-adaptor for B4 video lenses, but that's for 2/3" CCD camcorders...)
Otherwise on a 16x9 camera, you'll either be using spherical lenses and cropping top & bottom to get 2.40, or 2X anamorphic lenses and cropping the sides to get 2.40.
