24MP A7 and 36MP A7R

A7R has no anti-aliasing filter

Full manual control

Mirrorless E-mount

Super 35mm / APS-C crop mode

Likely 1080/30/25/24p video resolution with moire reduction

Built in OLED viewfinder mounted centrally over the lens block

Weather sealed body

Focus peaking

I am thinking this might be my B-Cam. Still waiting see it in the hand of the Pro. I think Sony is heading in the right direction.

Anyone think the video feature on this camera might be better then the Magic Pocket camera.
 
I've been waiting for this camera since i bought my first little NEX. Looking forward to seeing more (and being able to use my collection of M mount lenses 'properly')

We don't know anything about the video side yet, i'm more interested in stills but it could be really good. The HDMI out is uncompressed, we know that. What kind of signal is unknown, it could be 10 bit 444, but probably 8 bit 422.

I wonder if it skips or downsamples? The new RX10 (24MP) downsamples, so perhaps these follow suit. The A7R has gapless pixels, meaning no AA is needed (bit dubious there). The A7 has better autofocus though.

If it's good HDMI out, and downsamples then it could be a very nice B cam.

The LA-EA4 adapter is also released with this batch of new toys. I think it's just an LA-EA2 but for full frame though - don't think it offers any more.

Interested in these as well, though I'm worried about this line on the website:

Capture Full 1920 x 1080 HD uncompressed clean-screen video files with external recording devices via an HDMI® connection in 60p and 60i frame rates. Selectable in-camera AVCHD™ codec frame rates include super-smooth 60p, standard 60i or cinematic 24p, while MP4 codec is also available for smaller files for easier upload to the web.

That makes it sound like the clean HDMI output is only available in 60p/i modes, while 24p is reserved for AVCHD recording. An odd restriction...

Still, even with AVCHD alone it'd make a capable B-camera (and great for grabbing shallow-DOF B-roll alongside an FS700 A-camera).

No the quote you posted doesn't say anything like that. What it is saying that internal recording AVCHD can be 24p, 60p or 60i. That's how it is on all Nex cameras and that is inline with AVCH 2 specs.
 
Jordan Drake, who shot the above video on the A7, had the following (and much more) to say about video shooting specifically: I loved shooting video with the A7. All the controls were well placed, the viewfinder is such a pleasure to use, and seeing zebras, audio levels and peaking put me right at home…. [W]e had terrible light with a huge amount of contrast. It was a good test for the A7 as most cameras would struggle to handle some scenes. Looking at the video in post though, I was less delighted by the image. It is quite soft, and there was noticeable moire in several shots. I shot with the flattest profile, Neutral, with sharpening, contrast and saturation all turned down, yet the moire issues still surfaced. I’m hoping this was due to early firmware, I’ll test the video quality again when the production cameras arrive. As is though, while the Sony A7 image is nice, I’ll stick to the Panasonic GH3 when I need a small camera. Interesting read.

Is a video from the a7, obviously even at 1080p on youtube it's not a good idea to pull any conclusions.

It simply depends whether we're line skipping or scaling. A scaled 24 or 36MP image ought to be near damn perfect in terms of resolution and aliasing. Of course the AVCHD itself could be softening up the image, especially if it's prerelease firmware.

Anyway, this is a stills camera for me...
