I seem to not be seeing everything in my camera viewfinder. Is the EX-3 viewfinder supposed to be 100%? Is there a underscan setting I missed?

Thanks

Don't know about the EX-3 specifically, but I do know the EX-1 is 100% viewfinder accurate, and there is no "overscan" (or as Sony calls it, "Allscan") setting. I've tested it too.

upon further review, the matte box snuck into the upper right corner hiding behind the battery life indicator. I've learned to love the button that clears the frame of everything!

The viewfinder is 100%
