Nick Khoo recommend a few cameras for me. I found some examples on Vimeo and some internet prices.
– Panasonic HVX200
Apparently you can put Nikon lens on it or Letus Extreme adds depth to field which is 2,000USD. The camera alone is $3700USD
– Panasonic AG-HPX170
The Panasonic shoots in a slightly higher compression (shooting in 4:2:2) which is really good for green screen.
– Sony EX 3 which uses cheaper media (the SSX cards) but they don’t record as good quality picture (the compression is slightly higher)
