EVF is now on sale, first users in China just bought them.
Actual price: ~104 $ (650 yuan), but it will drop to level between 48-80 $ (300 - 500 yuan) if EVF will meet higher market demand.
HD screen in EVF is possible and it's not a problem for producers, but price will be higher.
EVF uses PAL, and video signal from camera, so with better internal screen and latest model of camera you will get more resolution in EVF.
In standard it uses 880mAh Li-ion 3.6V reachargeable battery, but some users use 1200mAh reachargeable battery.
EVF has a very low power consumption, it lasts the entire day taking pictures, producers tested energy consumption with Merrill cams and they notice ~ 50% lower energy consumption when main screen is turn off and EVF used.
In dp2m from nominal 50-60 pictures in high RAW (with main screen turn on) they could get 155 pictures using EVF and main screen turn off.
The viewfinder is suitable myopia.
"If the product will sold well, then we can think about adding diopter adjustment."
Review from one of users :
"This product should be named the Best Product Award this year at least, very practical, take pictures now, no looking back at the camera, and in all processes i no longer need screen, i'm completely taken over by the viewfinder display, and did not feel low resolution, greatly reducing the tremor when taking pictures and press the shutter the moment jitter. Now 1/15 dared to press the shutter, which in the past, I have at least 1/125 shutter was feeling more reliable."
