This is a challenge to see who's camera system can bring the best image, not a workflow contest. To do a test to see who has the best or fastest workflow I would say is nearly impossible given how many different workflow exists for every camera system and editing suite.
And I believe including DSLR in this challenge is actually quite fair, but only with the DSLR in stills mode. After all Red's DSMC concept directly challenges still photography cameras. Only difference Red's stills mode is same as video mode, but you would shoot it as you would shoot still photography. C300 and C500 is made for digital cinema so both are fair game.
So can we please keep on topic of the challenge and you guys can argue workflow in another thread.
