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

AlphaLux, I do not get it. Is it not that light gathering ability is more on full frame, hence should get higher shutter speed ?

I did some test today as per the suggestion from the other posters. Manual mode, F 3.5, ISO 3200, Spot Metering, straight JPEG out of camera. Still A7 is registering slower shutter speed compared to 5N.  What is going on here guys???

A7, ISO 3200, F 3.5, Shutter Speed is 1/8

5N, ISO 3200, F 3.5, Shutter Speed is 1/10
