I also predict D90 will change the indi movie world and put a huge
damper on the RED company. Many indi movie makers love HD but don't
like the deep DOF and long for the shallow DOP of 35 film. Guess
what? They got their wish for less than $1000 on a system that
already has numerous amount of quality lenses.
Depth of field will be very similar between the D90 and the Red One
camera as the sensor sizes are quite close. (The Red is likely a bit
larger than the area used in a D90 for video.) Not even considering
the difference between 720P and 4K, in terms of actually shooting a
movie for real, the D90 isn't going to work and the Red is already
being used by a lot of top name directors and cinematographers.
(I am assuming the D90 uses the entire sensor width and downsamples
appropriately. If it windows the center of the sensor, then it will
have small sensor depth of field properties similar to existing
consumer video cameras.)
