Hi. Im in the same of my bro. Ive been used raw video in my 600d for two years, and i love it. Im planning to upgrade for other camera, and i was looking for the 50d, cause it is 70mb/s card, same as the 5d mk ii.. However with this new sd card hack the EOS-M becomes an option for me, cause is possible to record 2.5k RAW, right?
In my country, Brazil, both camera are R$1.000,00 =/ yes....
Should I go 50d or EOS-M? Why choose 7d I don't know.. is a lot expensive and just 40mb/s Right?
So... 50d or EOS-M?
The greatest point for me is: 2.5k just in crop mode.. but what about no-crop mode?
EOS-M >>
* What are the resolutions for continuos and for few seconds?
*How are the results with moire and aliasing in non-crop mode? Same as my 600d? If it is is fine to me

*If should I use just in 5x crop mode, is 1.6x crop factor from APS-C then plus 5x from the crop?
So it is impossible to shoot a subject near from me cause it has a lot of zoom?
In my 600d I use an 18mm lens and put it in 720p, what give me 6s of continuous, is just fine for me, I can shoot near my subject, I can even use my 50mm 1.8 the I love, some time i use the 55-250mm all in no-crop mode, what give me a nice range. ......... BUT in the EOS-M ll not allow me to do that?
I don't know if I make myself clear, however sorry for bad english and thanks for someone with a goos soul to help me to choose..
Before I go I have another questions hehehe.....
* what about the EOS-M battery shooting in raw, cause i didn't see any battery grip.
