Hi dave – if you want a professional “cinematic” large sensor camera for TV promos below $5000, the $4999 (body only) Canon C100 and the $4499 (with 18-200 manual zoom lens) Sony FS100
are pretty much the two best choices on the market today.
Here is what the C100 can do: https://vimeo.com/56133010
Here is what the FS100 can do: https://vimeo.com/39060434
If you can wait a few months, the recently announced 4K Panasonic GH4 (~$1699) with its DMC-YAGH Interface Unit (~$2199) will give you a lot better image quality for your money (10-bit versus 8-bit, and 4 times the resolution of 1080p).
Here is what this camera can do (please watch at your monitor’s maximum resolution): https://www.youtube.com/watch?v=hHKJ5eE7I1k
Hope this is helpful!
