Thanks Fred. The pic of it next to NEX 7 w/ the 24/1.8 on the 7 is interesting. I didn't realize how small the 35 actually is. Sweeeeet.
The good news translates to weight (and volume) too.
Weight: The A7r and FE 35/2.8 weigh 585g (just over a pound). The D800 and Sigma 35/1.4 DG weigh 1,665g (3 2/3 pounds).

Sorry if it has been covered, but as the A7(/r) have NFC and Wifi have anyone seen or know if you can get the camera maneuverable via a smartphone such as e.g. the Canon 6D?

not sure you can make it walk or run, but supposedly we'll have smart phone apps for use as remote.

At 2 full stops slower. Not really surprising that a 35/2.8 is a lot lighter than a 35/1.4.
A 300mm f/5.6 is a lot lighter than a 300mm f/2.8 too, but it's not exactly a fair comparison.
I'm looking at it the other way - A7 + 35/2.8 will not be much heavier than 5N and 24/1.8, and DOF will be similar-ish. I can plop the 35 on the 5N that I plan to keep, for a nice 50mm FOV. I'll also keep my Sig 35 for Nikon, and can adapt it. It was actually pretty stellar on 5N wide open, the few times I tried it.
The glass is half full, and I am digging the Kool-Aid.

funny
Someone from the knowledgeable part of the crowd that knows? I am talking about getting the VF on eg an iPhone screen, change settings and make the shot. Thought this was obvious.
The NEX 5T can transfer images wirelessly which is neat and fine, but tech doesnt limit to that.

Ok, with the 35 f/2.8 Ai-S it would weigh 1140 grams and that doesn't even include the battery. The bottom line is that the D800 combo weighs over twice as much and even though it is a MF lens (which should save weight) the 35 f/2.8 Ai-S also weighs twice as much.

And focusing a 35/2.8 might present some level of difficulty to many D800 users.
You would still have the last gen sensor in a 1000 gram body that looks like a flotation device and takes a battery that weighs half the 35/2.8. Take a spare and it's about the same weight.
585 grams is a mere 100 grams more than an RX1, by the time you add a grip and case, it's a wash. Sony gives you two ways to shoot 35mm with a light carry, AF or focus aids. One has a 36Mp sensor...the other lens-sensor matching and an extra stop. And beautiful bokeh, which is becoming a hallmark of recent Sony cameras and CZ lenses made for them.

The only thing the A7 shares in common with the A99 is the MP. Otherwise, I don't see anything of the A7 in the A99. Choosing the A7 over the R versions is more likely because of the less noise at the pixel level and less constraint on the computational power (both of which are because of the less MP).
Actually that is not really true. The A7 and A-99 share the same FF sensor not just the megapixel count. There is nothing really new about the A7 sensor. The A7 does *not* have a new on-sensor phase detection different from the depth map pixels available on the A-99. (see http://www.chipworks.com/components/com_wordpress/wp/wp-content/uploads/2013/08/Fontaine_Innovative-Technology-Elements-for-Large-and-Small-Pixel-Imaging-Devices.pdf for information about the A-99's AF pixels) . Both the A7 and A-99 sensor & firmware cannot compete with the AF performance of the Canon 70D which actually has a novel and impressive dual-pixel phase detection system that can compete against traditional SLR auto-focusing.
The A7's AF performance is still in the same ballpark of the A7r's for most purposes and neither can handle continuous AF tracking of moving subjects.
In fact if you want to shoot Alpha lenses with your A7, Sony will sell you a full frame LA-EA adapter that has a traditional dedicated phase detection sensor along with a translucent mirror. There is no option for a fully A-mount FF LA-EA adapter for the A7 which does not come with light robbing translucent mirror and AF sensor.
Really nice product guide. I actually learned something in the EVF info:
"Even bokeh is displayed with all the subtle characteristics that will appear in your final image. This is a
decisive advantage over optical view-finders, which display bokeh distorted by the focusing screen".
