eos 50-D super low light

[sick stu]

hi all, When ever i get a new video camera i always try a super low light test. After buying a 50d a few weeks ago ive been trying out the RAW video option. Having RAW video to a Low Budget Film maker like me is a god send.
So here is a quick and dirty low light test with a old Olympus (mc) 50mm F1.8

Also at 1min55sec as the van passes the frame you will notice that a auto exposure adjustment happens.
im not sure why this happens as everything was set to MANUAL. Ive noticed this on some other shots
ive done when ive been panning from a darker image to a brighter image, ive owned 7D for almost 3 years
that ive used for video only and never noticed this on the 7D. i tried the AEB option in the CANON menus to
try and bracket the exposure shift, ive also tried the AV/TV exposure lock option but the exposure still
seems to shift. If anyone could shed some light on this i would be grateful.
My next test are going to be with my ANAMORPHIC lenses...cant wait!
I would like to thank the Magic Lantern team and all their hard work.

On the exposure, check your "Gradual Expo." settings under the movie menu in ML.  Make sure that is off, or set to high number of frames before it changes.  Otherwise, I notice changes too sometimes.  And get a vimeo account if you can.   In Vimeo you can go full screen or have the option of not scaling, or showing in native resolution.  Nice work!

aaaaaaah, i'll try the "Gradual Expo." (this has always been set to off) i'll try the highest frame setting so the exposure ramp will be very sloooow. that should work fine for now. "Exposure Overide" has always been 'ON'.
I'll do some more tests today as im going shopping to dusty piccadilly circus London sunday afternoon GMT. i'll choose
a picture style with BOLD colors like LANDSCAPE. (i find any excuse to shoot RAW now)
***OH and for anyone who's interested im trying some re-chargeable 'DURACELL' batteries (DRC511)
that are only £14.30 from Currys/PC world. They charge up fine in the OEM canon charger, show remaining power
on the camera display and last just as long-ish (turning off camera between takes) 2 weeks of usage seems fine so far.
