There's 3 advantages or manual focus ing with a high-end EVF. The first is the zoom function. The second is the ability to accurately show DoF and critical focus at working apertures (Most optical finders do not accurately show DoF even wide-open). Since the feed is from the imaging sensor, misalignment is also impossible The third is a peculiarity of the LCD display and how it displays the transition between oof and in-focus textures. It becomes quite easy to determine when you hit focus based on the look of any texture or detail. -- M.
