Meet Sony's New Mirrorless Full Frame A7 & A7R Interchangeable Lens Cameras

The main differentiation between the $2300 A7R and $1700 A7 is the aforementioned 36 vs. 24MP CMOS sensors, respectively, though both sensors are full frame size. Additionally, the A7R excludes the optical low-pass filter deployed in the A7. With its 36 un-antialiased megapixels, the A7R will probably be less apt for video shooting than the A7. Along with the newly announced fixed-lens RX10, the A7 & A7R feature the new, scary-sounding BIONX X image processor. Here are some beauty shots of the A7R (which looks very much like the A7 as well):

Apparently, the A7/R's new 'FE' mount natively accepts NEX E-mount lenses and automatically crops non-FF E-mount glass by the proper factor. Conversely, the new lenses announced alongside these cameras may be mounted on other NEX or E-mount bodies. Alpha mount glass may be affixed using something like the $350 Sony LAEA4, or the cheaper LAEA3.
To give you an idea of how small these guys are, check out this video by The Camera Store via SonyAlphaRumors:
As Chris points out in the video above, the convergence of size, lens interchangeability, full frame, mirrorless and video qualities make these cameras pretty significant developments. And, according to DPReview, "Sony is also unifying the Alpha and NEX brands, so all future interchangeable lens cameras will now fall under the Alpha umbrella."
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.
This may be why you don't often hear about Sony's photography cameras being used in place of other DSLRs for video shooting. That said, the A7 & A7R provide the aforementioned audio meters and zebras, as well as optional XLR input via another adapter.
According to DPReview, Sony plans to have 15 FE lenses available by 2015. SonyAlphaRumors has a pretty extensive running list going of body and kit items related to these announcements, so check the links below if you want to scope these newcomers, or their accompanying accessories.
