Guys, you don't calculate crop factor and equivalency of f-stops when it comes to light gathering capabilities. Only in depth of field comparisons. As far as exposures go, the f-stops will be the same

That is incorrect, the DOF and amount of light are affected to the same degree by cropping. You need to multiply f-stop by the crop factor to get equivalent settings on both cameras. The ISO can be set on auto, it doesn't really matter.
