This is from DPReview: Viewfinder Electronic Viewfinder Color LCD Viewfinder Field of view 100% Eye point 14 mm at -1 dioptre Magnification 1.4x (equivalent to 0.7x on a 35mm camera / 50mm lens) Dioptre adjustment -4 to +4 dioptre 1,440,000 dots* Field Sequential (RGB) *(the next page admits that this is _effective_ resolution, so the number of pixels is probably similar, to the rear screen, but as they are a different aspect ratio the pixel count along the sides won't be the same) LCD monitor 3.0" TFT LCD monitor Multi-angle swing and tilt (180°swing, 180° swivel) Low temperature Polycrystalline TFT LCD 460,000 dots 60 fps Approx 100% frame coverage Auto Power LCD (optional) adjusts brightness in bright light So you see the EVF and the rear display are _not_ alike. The key difference is that the EVF is a "Field Sequential" display. This was explained in my last post on the subject. It's in the archive, for those who've binned it unread. Briefly, the EVF uses a sequential display on a mono screen. The pixels on these screens do not have black boundaries between adjacent pixels. In fact, adjacent pixels have no visible boundaries. Each pixel displays full RGB information, in a sequence too rapid for the eye to separate. In comparison, the rear screen displays only one primary colour at each pixel. By rights, these displays (RGB matrixes)should quote an effective resolution only one third of their total pixel count, but we consumers have been hoodwinked by marketing-speak to the extent that we accept the lie. The same goes for Bayer-matrix type sensors. It's interesting that DPReview accepts Panasonic's rationalization of the pixel count for this screen, but previously gave much grief to Fuji for their SuperCCD, and to Foveon for their sensor, by refuting their rationalizations for higher pixel counts.
