While many photographers swear by optical viewfinders, it’s clear that much of the camera industry is shifting over to electronic — or hybrid — ones to offer high-tech features such as overlaid information displays. Thankfully, many of the old problems that existed with EVFs (e.g. low resolution) are starting to disappear. Case in point: French company MicroOLED has just announced a new microdisplay that packs 5.4 million dots into the highest pixel density viewfinder ever seen. To put that into perspective, the highly-reviewed viewfinder found in the latest Sony mirrorless cameras are only 2.4-million dots. MicroOLED is said to be targeting professional cameras with the display — as well as military and medical purposes.
