You can choose between Canon and Sony, but at a very steap price. They only record in HD. The cheapest is a Sony HD Handicam thats 1995.95. The really good ones start at $5000.00 and up but they are for professional use.
Check out the Panasonic PV-GS400. It'll run you around $1000 and records in true widescreen. Check out the reviews at http://www.camcorderinfo.com/content/Panasonic-PV-GS400-Camcorder-Review.htm
If your not looking for the most expensive then the sony dcr hc42 is a good buy. It does widescreen, has a color touch panel and is under $500.
If you are looking for consumer cameras that capture widescreen, also known 16:9 then you will have to make sure that the camcorder CCD or CMOS thats the picture sensor chip, has to be 16:9 Native, i.e its physical size has to be 16:9 in shape. Usually only profesional/semi-profession cameras have native 16:9 chips. Thus it is unlikely that consumer cameras will have native 16:9, generally some cameras offer "16:9" modes, beware this are just usually done by masking off the top and bottom of the picture with black bars. Check the camcorders manual for technical specifications for 16:9 size chips. I can not remember of hand if any consumer cams have native 16:9 chips, you will have check for your self. @ AE27 if by HD Sony cameras you are indicating the Sony HC1 and Canon XHL1 then you are no quite right in the sense that they can actually reocrd in SD mode or normal DV mode. The HC1 also also has a downconversion feature that downconverts the HDV into DV. Both are HDV cameras. HC1 is actually a consumer HD cam, where as the Canon XHL1 is "prosumer" due to its interchaneable lens and SDI interface. Hope that Helps Anhar Hussain Miah
