Sony and Panasonic announced several new cameras that sport OLED viewfinders. The three new cameras all use XGA OLED microdisplays (probably the same microdisplay).
First up we have Sony's a99 Mark II, a high-end 42.9-mp A-mount SLT camera that features 4K video capture, 5-axis image stabilization, 79 AF points and a newly designed shutter. The a99 Mark II will ship in November 2016 for $3,200 (body only).
Panasonic's Lumix DMC-FZ2500 uses a 1"-type 20MP sensor, 24-480mm F2.8-4.5 lens, 4K Video-support and Wi-Fi. Panasonic's 2nd camera is the Lumix DMC-G85, is a mirrorless camera that sports a 16MP sensor, weather/dust proofing, 4K video support and Wi-Fi.
