Sorry lionhound, I forgot to reply to you.
I don't know much about either one of those cameras but I can help you pick the right one.
Are they digital?
Does either one have a thing called a CCD?
If it does, how many? the more the better
How many pixels is each CCD? again the more the better
A CCD was explained to me like a roof top of a house gathering light from the sun. If there are 3 each one takes the job of gathering a certain color (red, green, blue) The more pixels it has the larger the gathering surface is henace the higher quality.
I use the Cannon GL1 it has 3 CCD and each one has 250,000 pixels. It costs around $2000. The XL1 that yogo7788 was talking about costs around $4500 with out the high power lens and I think it has 500,000 pixels per CCD. Both these camera are in the perfesional catagory. They do have what they call Broadcast quality. So get the most pixels with the highest power zoom and the camera will probaly come with every thing else you need. Good luck and try some web sites that have rated or compared those to cameras to each other. One thing I just remeberd on the sony versus the cannon high end models is one test performed was to determine how well the cameras processor could determine what it was looking at. They filmed tapered black lines and then posted a picture of each cameras ability to follow the taper to the end with out pixelization. The sony did a better job at that. Good luck and hope to share film with you some day.
