I just picked up a second-hand EM5, and I'm having the oddest thing happen. Every picture I take, regardless of the white balance setting, is coming out looking as if I'm shooting through a red filter. The exact color of red varies, from deep magenta to orangy-red, depending on the WB setting, but they are all red. The only exception is the first one-touch setting, which strips the image of all the red, including the red that should be there, and leaves it a strange cyan/magenta duotone kind of thing. Has anyone had this happen? Did I accidentally tweak a setting while I was exploring the menus, or did I get a dud camera?
