Different cameras... different ISOs?

[Kabuto1138]

Hey gang, I am prepping a video shoot with a 5d2, a t2i and a t3i.  Trying to make them match as close as I can, so i was wondering, if anyone knows, how different are the camera ISOs from each other's?

thanks!

I know some review site tests sensitivity in comparison to the real ISO standards. DXO Labs or something like that. Canons in general run a little on the less sensitive side if I remember correctly.  I doubt that the difference between any model is going to be more than 1/10EV at any given setting.

You might see a minor difference between the t2i/t3i and 5d2 due to the different sensors, but definitely no noticeable difference between the t2i and t3i. I use a 5D2 and 60D for weddings and never had any trouble of footage not matching up.. just make sure you're using the same settings (picture style, wb, etc.) and you're good to go
