I agree that the A7s, GH4 etc. are on a different level to the 600d, however with the right setup you can get some brilliant stuff from it (particularly if you use magic lantern)
Check out some of Simon Cade's stuff and you'll see what I mean...
At about 2:10 on the video he shows the built in ND filters on the camera (1/4, 1/16, 1/64).
That said I do agree that there are definitely other options that would outperform this camera.
I just edited my latest project with this layout, for the second time. I find that it is a much quicker and more efficient way of editing (for me, that is).
Is anyone else having problems with SpeedGrade?? I have used it for several years and it has worked perfectly on my 2012 Macbook Pro, but I have updated it to CC 2015 and all of a sudden it is running incredibly slowly? Help!!
Great Short!! Brilliant cinematography, I especially loved the deep colours.
My only criticism might be that the CG Deer in the tunnel pulled me out a bit, but I really am nitpicking.
Especially impressive considering it was shot only on a single day!!
