Canon Wide Angle Lens
Canon XL2 lens wide angle options?

I have a Canon XL2 Prosumer both the lens of 16x and the 3x wide angle lens. The wide angle lens does not give me a wide enough aspect ratio considerably. Does anyone have any idea or suggestion on what is available? Thank you. Or just be better to go with the optional EF, so that all basic SLR lenses can be used. I need something with extreme wide angle.

How wide of an angle Do you need? The XL2 has a very decent lens, which uses a CCD 16:09, unlike the XL1 that only uses a standard CCD.
