AndyW17: Why is the flip-up viewfinder useful? I can see it if you're using a short tripod or a cat up a tree - but otherwise? What am I missing?
Even though pivoting LCDs can be used this way, outdoors an LCD facing the sky is all glare and not much contrast, this adds stability from your eye and gives you a good quality view from a low angle.
Reflex viewfinders are not a new idea, they've existed optically for years, and Sony sells optional EVFs that pivot and go on RX1 or some NEX models. It lets you hold the camera in a stable position with your elbows at your sides and shoot from a lower angle as you'd want to with children or fashion.
hugh crawford: What use is 4K at 25fps ? Just curious.
As far as I know there is no display standard for 4K 25fps and 4K is a ciniema production standard for movie theaters
It's not like they have a 4K at 30fps option either.
What's the point? Lots of points!1. Think of it as a "burst mode" that captures 8MP stills, but can grab 25 of them in a second.2. Allows for post-production, including zooming & cropping into an image, to output full HD video.3. Capture panoramas with ultra-wide adapters, then crop down to the part you need.4. As you said, 4K is already a standard in theaters.
The ideas behind the product (computational photography in general and light field capture in particular) are more interesting than the first product itself. Even if they never make a competitive product, at least they are building a collection of patents that could pay-off as other companies eventually adopt parts of what they first brought to market. I can't wait for the day when depth is captured along with every image, so foreground and background can be adjusted separately in Lightroom, for example.
Pr0peller: Why manual focus? Because autofocus is useless in some cases, like shots of birds in deep foliageWhy 46M sensor? Because you may crop the aforementioned birds, and still get an excellent image.. No need for zoom..Why 45mm lens? Because you may take pics at 1/45sec or lower, hand-held without problems..
I'd say you'd need some knowledge of photography before throwing stones on dpreview..
It's really a 14.6 MP sensor in terms of the number of pixels. Yes, it has three layers so they say x3, and will hopefully have high quality per pixel, but if you crop out the center 1 or 2 MP to get a bird, you'll only have a 1 or 2 MP image left to print.
"capture seven pixels of information"
Probably meant seven *mega*pixels there.
There's a mistake on this page: The stats on the left column, and links to more info, are all for the T20 (from 2007) not the newly announced TX20.
BJN: The 3D bit sounds like a total gimmick. The baseline separation for decent stereo effect at tele range is too narrow. I wonder what leaving out that feature could have done to the retail price? 5.4x is pretty weak magnification for a lot of binocular use.
I didn't see any reference to the light gathering capability of these optics. The objective lenses look tiny, so I'm guessing the view is pretty dark and photo/video operation will require bright light for decent quality.
You are only looking through a pair of digital viewfinders, no OVF, so the image might appear bright enough, and could just get noisy or have reduced color accuracy in dimmer settings. I think it'll be a few years before manufacturers of conventional binoculars have to fear Sony as a serious competitor...
AlfBundy: 24x36 equivalent is in 2D : optical zoom 66mm-660mm (with digital 20x zoom : 66mm-1320mm)in 3D : optical zoom 33mm-330mm (no mention of digital zoom in 3D)

Watch the video review (subtitled in english).
As AlfBundy said, he's comparing to a 24mm x 36mm (such as a full frame dSLR sensor or 35mm film frame).
techmine: how big is the sensor?
@M Jesper - The sensor isn't "behind" the lens, there's a mirror or prism behind the lens and the sensor aims upwards at it. This kind of bent optical approach is why the zoom lens doesn't need to extend...
