I'm just learning how to use my new GX7. The camera has two features to assist preventing overexposure in the highlights: 1. Histogram display 2. Display white saturated areas in Auto Review (manual p 79) I find the second feature more useful but the highlighting is only displayed after taking the photo. Is there a way of displaying the white saturated areas whilst composing a photo? I have an Olympus C-5060W camera from 2003 which displays both over exposed and under exposed regions whilst composing.
