E-M1 delivers nearly impeccable performance worthy of its flagship status. This model features a state-of-the-art 16 megapixels CMOS sensor with built-in Phase-Detect autofocus while keeping its predecessor's 5-axis image-stabilization and super-sonic dust-reduction systems. It is also one of the few Micro Four-Thirds cameras without an anti-alias filter. Combined with the new autofocus system, the E-M1 is designed to take full-advantage of Four-Thirds lenses made for Olympus DSLRs.

Anybody experience problems with the EM-1 video, I'm finding my copy has frames jumping around, tried all setting sand currently very disappointed c/w GX7?
This 34321 could not be found in the Panasonic's site. But the MN34230, yes:
http://industrial.panasonic.com/www-cgi/jvcr13pz.cgi?E+SC+4+CGA7001+MN34230+8+WW
And this is interesting: "Features 1080p/60fps, 4k2k/30fps"
You're correct, but wide lenses have larger depth of focus, and thus less problems to AF.
Besides, the phase detect photosites which are used for focusing don't gather any image data. This means the information needs to be interpolated - just as it would with a dead pixel on the sensor. To avoid "dead" photosites Panasonic proposed to use off-sensor reflected image to the separate phase AF sensor, but I'm not sure if this idea would ever see the light: http://egami.blog.so-net.ne.jp/2011-08-29
They are still different and both can be used. DFD works best if difference is big, it's performance will drop for wide lenses.
@Vitaliy_Kiselev I don't think that it has much sense for Panasonic to use the Phase Detection in its cameras, particularly when they have an alternative 'Depth from Defocus' (DfD) method to help the contrast AF. Here is a scientific paper showing that Phase detect and Depth-of-Defocus AF should have similar performance: http://webee.technion.ac.il/~yoav/publications/dfdstereot2a.pdf
Where is this sensor in Panasonic cameras?

"Voldemort has stated in his article that the EM1 can do live digital teleconverting / cropping during movie filming to get a closer view. Does anybody have video samples of this in action?
Quote from Voldemort : "It has another major trick up it’s sleeve and that is a rolling crop mode which can be toggled on and off DURING a shot. You have a green box and it can be moved around the frame. This can zoom in on any area of interest anywhere in the frame and give you a Blade Runner style enhancement of the area with plenty of extra detail."
Here's a couple of examples for you. Very cool feature. Sometimes the effect looks seamless but sometimes it doesn't :)
I've really been enjoying using the E-M1 for video. I used to have a GH3 but I just love the IBIS on this thing !! I'm a a total newb when it comes to video, but the freedom the E-M1 gives is amazing. So much fun wandering around the streets with this stabilised cam :) I shot these over the last couple of weeks and edited them on FCP X which I'm trying to teach myself.
I'm usually using Vivid picture mode at defaults with contrast set to -2.
The first two were shot with the Pana Leica 25/1.4 and the third with the 14-42 PZ.
In some of these clips, especially the first one, you will notice flickering lights. This is because I live in a PAL country, Hong Kong, where it's 50Hz. Shooting at 30p, I usually use 1/60 shutter, but have learned that under lights shooting at 1/50 stops the flickering.
Been into street photography for a few years so trying to adapt this to video making some street "clips".
All hand held ... I'm allergic to tripods which is why I love this camera so much !!!

Autofocus proved as fast as we’ve experienced. The AF tracking kept up with speedy subjects and did a great job. Video looked very pleasing, with minimal artifacts and not much jello effect.
The OM-D E-M1 is one of the best current ILCs and marks a high point for the Olympus system. Extremely versatile controls, a rugged body, and a lovely EVF combine with some of the highest image quality you can get from any camera.
