cool, I keep the old computer and the old version...
Cool, now we can have exactly the same picture a million times over..... In the light of reducing environmental pollution, I suggest only the first person takes the shoot, and shares it with the remaining 999'999...
kimchiflower: Good luck shooting at 1056mm f/6.5
Not sure what's more futile, the megapixel race or the megazoom race?
Well, it might actually not be that bad based on the superzoom bridge cameras, if image stabilization works ok.
What's more futile is that at 1056 with aperture f6.5, on such a small sensor, you might actually only get about 2Mp effective resolution due to diffraction.
wallbreaker: I wished it was 1 inch sensor
Then it would only be a 500mm (35mm) equivalent lens at the long end, ignoring also the diameter which will not be big enough to avoid vignetting.
Cameron R Hood: The distortions in that lens must be unbelievable.
That's why it seems that you can't get any RAW files from any of these superzoom bridge cameras. Distortion, CA will be corrected directly in camera.
forpetessake: As it was predicted DSLRs won't surrender to mirrorless without putting up a good fight. This is the first such blow -- a camera almost as light and small as mirrorless, but with the full DSLR advantages with hundreds of DSLR lenses fully compatible.
Competition is good, keep them coming!
P.S. It actually beats Olympus OM-D in all respects including weight! See comparison: http://www.dpreview.com/products/compare/side-by-side?products=canon_eos100d&products=oly_em5
Mirrorless has only the advantage in lenses in the wide-angle range because of the shorter flange distance, so you don't need retrofocus designs in the 20-40mm range. For long focal lenses there does not have to be any advantage at all, if the pixel density is the same (e.g. a 24MP Canon crop, versus 16MP m4/3). Then you just crop the Canon a bit and you have the same resolution as the Olympus. Canon doesn't have a 24mp sensor yet, but Nikon/Sony already have. Well, one can argue that m4/3 can make more MPs on their sensor, but the problem is, you can't shrink pixel size unlimited due to diffraction. Even now 4/3 lenses are already loosing resolution from f5.6 on with a 16mp sensor.
They just bought it for the mobile versions, they rest they didn't care.
hmm, always something missing. Either you get RAW, but no GPS, or you get GPS, but no raw (e.g. Sony). Can't we have both?
Did I miss something? Where is the analysis of image quality under image quality? I mean slightly different colors or contrast can be adjusted, but which of these programs can produce, for example, the best looking output from a high ISO RAW in terms of resolution and noise?
ddtwenty: I am not expect to get camera with long zoom range. Just a shortter zoom range but to be more on tele end for example I like to see a compact body camera like this onlympus one come with super tele end with zoom power of only 8x like 125-1000 f2.8-5.6 with sensor size between 1/1.7inch to 1inch. But seem not any brands likely to introduce in to the market.
That's size is perhaps about half the size of APS-C (which is 1.6x smaller than FF). 1000mm (FF equiv.) / 1.6 / 2 = 300mm lens. Ok, look at the Canon EF 70-300 IS lens to see how big that will be

Pierre Couture: Same zoom reach as the Pany FZ200, but with lesser grip, and slower lens. I like my TZ5, but this kind of reach is too big without a tripod on such a small body.
Actually not. It works quite well on the Sony HX20V/HX30V cameras (500mm equiv).
anybody buying these cameras?
qwertyasdf: Does a hybrid mean putting 50% effort into PDAF and another 50% into CDAF?
And end up with a system that is 2 times slower than the competition either way?
I'm a Canon user, and has no intention to upgrade my xti.
"Does a hybrid mean putting 50% effort into PDAF and another 50% into CDAF?" No.
Standard PHAF works be redirecting part of the light from the mirror in a dSLR to a special array of phase detect sensors. PHAF detects correct distance, tells lens move this far, done (sort of).
With CDAF, you measure contrast on the sensor directly, you move lens a bit, measure, move lens a bit, measure until maximal contrast. Slow, but accurate (and no mirror of course).
With the new hybrid sensor, you make a few pixels on the sensor so that they can detect phase directly on the sensor. So, it should be an improvement over CDAF, since now the camera can tell the lens how much and in what direction to focus, this seems to be followed up with standard CDAF to fine tune focus (at least in the current 650D).
Here are some pictures of the hybrid sensor

The Schillings: Really nice shot. I find the image a little too HDR-ish. I think the foreground is too bright, and there are no distinctive shadows so maybe up the blacks.
agreed, too hdr-ish (at least on my screen).
Anyway, re: resolution, stitching is not such a big issue. The rocks don't run that fast.
EsVeeFoto: What about a tele zoom? It will be interesting to see how compact it will be.
Don't expect wonders. The sensor is still APS-C, so we are in the same physical constrained realm as the Rebel bodies. A 55-250 lens would essentially be that same as the existing 55-250IS. And longer lenses will still be like EF lenses, because focal length is focal length (unless you make fancy things like with the DO lenses), and f stop is f-stop (i.e. focal length divided by diameter of light intake).
The reason that P&S have small "long" teles, is that the sensor is much smaller, so that effectively a 100mm lens is like a 400mm or whatever. Effectively, you take your FF or APS-C sensor, and crop. In the future, when they have 100 Mp APS-C sensors, you just crop like crazy to get the same effect as a P&S camera.
Nishi Drew: Looks all great, but any word on pricing?
I think all these ND filters made of Cr-39 are "hand-made". I.e. Lee is, Hitech is, probably Singh-Ray as well. So prices shouldn't be higher than what is on the market.
I think they left the resolution low (at 22 Mp), so that the lens testing sites don't have to upgrade and redo all the lens tests with a new body....
:-)
Morgifier: This is a concise but very informative review with great sample shots, thanks!
I guess a lensbaby setup for my Nikon would set me back $600-$700; Are there any older tilt-shift lenses that I could pick up which offer a similar feature set for a lesser price?
Cheers,

hmm, not enough buttons on this one. It should have a button for direct upload to facebook, and a direct print button. Then there should be styles buttons, i.e. BIF eagles, BIF cormorants, BIF hummingbirds, Zoo button, Whalewatching button, Candid (Paparazzi) button, etc. :-). Finally a small black sticker that can be put on the front lens, to demonstrate that dust on the front lens does not interfere with the image.
