Hot Notes:
1) Pricing will be announced in mid March only! (Camera will cost less than $2000 or 2000 Euro).
2) This is the world’s first mirrorless interchangeable lens mount camera recording 4K
3) The external XLR / HD-SDI add-on for this camera allows for uncompressed 10bit 4K output over 3G HD-SDI – the kind of spec Canon currently charges $25,000 fo (EosHD).
4) DFD (Depth-of-Defocus) autofocus works like this: During live view (before a half-press of the shutter button), the camera will occasionally make a tiny adjustment to focus, to check whether subjects in the frame are in front of or behind the current focus point. In addition to this information, the camera judges how far out-of-focus objects in the scene are, based on how blurred they are, assessed using a profile detailing the blur behavior of the lens at its current aperture. Although this combination of data itself doesn’t give the GH4 enough information to achieve precise focus, it does give it a clear idea of where it should start using conventional contrast detection AF process to achieve fine focus. (Dpreview).
5) Recording 4K will crop your image by an ulterior 1,125x (Cinema 4K) or 1,2x (Cinema) factor (Personal View).
6) The new sensor seems to be able to get more detail out of the highlights than the sensor in the Olympus EM1 (ThePhoBlographer).
