EV Shift

Hi Guys

With weddings sometimes I come up with rather tricky backlighting situations and on my old Panasonics I quite often used to use the quick fix of the backlight button and that worked perfectly in 95% of cases where I had bright water/sky behind the bride and groom (yes they decided that's where they wanted to stand and no-one was going to convince them otherwise) The other 5% needed total manual exposure which as a single shooter is tricky for me if the light does change and I'm not near the camera at an outdoor wedding.

Now, on the EA50, I want to assign EV Shift to a user button so I have a "backlight" button but does anyone know roughly what the values will change exposure by ..It goes up to EV 2 and also down to -EV2 but the manual doesn't tell you if "one EV" equals maybe 1 stop or half a stop

Does anyone know what the standard here is?? How are EV values calibrated on a DSLR ..maybe they would be the same???

1EV = 1 stop
