Epson make a technology called Ultimicron for use in electronic viewfinders (EVF), these are designed to give natural brightness, natural defocusing effects, and no colour breakup, for example when panning from left to right. The EVF is used in the Olympus OM-D E-M5
, with an 0.47 inch 1.44 million dot (SVGA) EVF, although it could be in other products that have not yet been announced, or alternatively some manufacturers do not wish to divulge who is the manufacturer of components in their cameras.
The latest 0.48 inch EVF features an XGA resolution, and 2.359 million dots, Epson also make an 0.52 inch EVF with a QHD (960 x 540) resolution that works out at around 1.7 million dots, although what these last two EVFs are used in has not been disclosed. Interestingly enough the new Panasonic Lumix GH3
features a 1.7 million dot resolution EVF, although this uses OLED technology, which is not the same as Epsons.
