It's Not An EVF It's An LVF : How cute, your DSLR shoots 1080p? Panasonic’s Lumix GH4 does 4K

Panasonic has also added focus peaking to help users who prefer to focus manually (by showing the peak of focus as you adjust). In addition to the 3-inch vari-angle OLED display, the GH4 has a bright OLED viewfinder (Panasonic calls it the Live View Finder, or LVF) that’s incredibly responsive and accurate when we gave it a whirl during a press briefing. As we expected, electronic viewfinders in high-end cameras will become as responsive and useful as their optical counterparts, and the GH4’s didn’t disappoint. The GH4 has a highlight and shadow control function that lets you make those adjustments via live view.
