Can I see them at an electronics retail store?

Are there Sony or Canon stores?

I really need a bunch of answers answered professionally. Maybe I can call the companies?

Oh and on panasonics website here what is the difference between the cinematogrsphy cam and the others are there more gadgets or something and what do they do? http://www.panasonic.com/business/provideo/cat_camcorders.asp

*Maybe* bhphotovideo… in New York. But generally, consumer electronics stores do not carry pro-grade gear.

And if you have that many questions – and do not know the difference between the Varicams and the rest of the Panasonic pro gear, (or the CineAltas and the rest of the Sony pro gear), you might want to re-think you training and consider a more manageable camcorder to match your abilities…
