Нуу так дайте ссылку, я не нашел. или тут опишите в кратце) ведь количество точек одинаково, это офф. инфа , а размеры разные... получается что либо у самса эви четче но меньше размером, либо наоборот...Подробнее
наоборот. сейчас с телефона не найду ветку на dpreview... поищите. там вся инфа была.. давно еще смотрел
вот копирую отсюда
The OM-D E-M5's electronic viewfinder (EVF) provides a 100 percent 4:3 view with a resolution of 1.44 million pixels (800 x 600 pixels) and a quoted magnification of 1.15, these are the same specifications as the VF2 accessory viewfinder for the PEN (and the E-M5 if you're so inclined) models. The OM-D E-M5's viewfinder isn't quite as large as the Lumix G3's which it matches in terms of resolution, but the image looks more stable even in the default mode which refreshes at 60Hz. You can also set a higher frame rate which doubles that to 120Hz. The NEX-7's EVF remains the one against which all others are judged, though, and its viewfinder boasts a higher 2.4 million pixel resolution
as well as being bigger.
Compared with an optical viewfinder on a cropped frame budget DSLR like the Nikon D3200, the E-M5's viewfinder looks larger, but one thing none of these EVF's can match is the brightness and direct response of an optical viewfinder which provides a more 'real' view of the scene in front of you, mediated only by glass and mirrors. Comparisons aside, in use the OM-D E-M5's viewfinder feels quick and responsive and, while there will always be those for whom an EVF, no matter how good, is second best, in most situations I found it more than adequate. And there are some things an Electronic viewfinder can do better than an optical one, like information overlays and effect previews - I'll talk about those in more detail in the handling section.
When the eyepiece proximity sensor detects your eye the EVF activates and the OLED screen switches off. In default mode the screen displays information but it can of course be used for composing by pressing the button next to the viewfinder. For the OM-D E-M5 Olympus has stuck with the excellent 3 inch 610k pixel touch OLED screen used on the EP-3 and it has the same 3:2 proportions which means there are narrow black bars down either side when in live view mode.
The screen flips out on a cantilevered hinge and can be tilted up into an almost vertical position and downwards to 50 degrees. Olympus has managed to integrate the touch screen on the PEN E-P3 so that it complements the physical controls and provides genuinely useful extra functionality and that's also true of the OM-D E-M5. With Super Control Panel display you can just tap the setting you want to change and in 'Live view' mode touch to focus is swift and sure. It is however worth noting the screen on the rival Lumix G3 is fully-articulated and can both flip-out and twist to face any direction rather than just tilting vertically.

насчет ЭВИ самсунга толко одно слово - decent:

The Samsung has no optical viewfinder,
though it does have a decent electronic viewfinder (EVF) and a very nice, swiveling, 3-inch AMOLED display on back to help you compose photos from unusual angles.
Автор явно не хотел заострять на EVF внимания...
