I have a Sony DSR 300 and two available lenses: a Canon YH18 and a YH14. Is there any anamorphic converter lens compatible with anything on this camera? I'd really like to shoot anamorphic 16:9 with the 300 but I can't seem to find anything! Also, does it make a difference if I find something for the camera or for the lens? I just don't even know what to search for.
