hmm, somehow reminiscent of the car companies 100 years ago, lots of different brands, or the PC market 30 years ago, then the shake out. Seems like every company is trying to do something else, who knows what's left in 5-10 years. Perhaps Canon is not so stupid, they just wait and see what the competition is throwing at the market, maybe they will get it right by being last?

Ashley Pomeroy: "from a wide 24mm to an amazing 1,000mm* "

There's a * there - typo, or is there some kind of catch (e.g. the 1000mm isn't really 1000mm)? Otherwise this'll be fascinating for checking out the Apollo landing sites. Also, it sounds like the ultimate beach pervert camera.

* Equivalent in 35-mm [135] format

IcyVeins: 1000mm reach? Are they out of their minds? Who could possibly care to zoom in that far?

For birding, surfing and other far away things it would be very useful. However, what I would like to see is how these long P&S cameras that have 800mm or longer actually perform. What is the quality of these pictures at these lengths compared to say a Canon 100-400L on an APS-C camera. Can you get the same quality with a 300mm lens on a dSLR, because the P&S are not that great, are do they offer significant improved resolution compared to a dSLR?? (Ignoring the ISO/light issue).

Kriwoel: How about better 3D camera like RAYTRIX ? any review?

They seem to be going for the high-end market, vertical applications. But in any case, it's the same technology. In their documentation about lighfield/panoptic cameras, the even refer to Ng. So, what's the patent situation?

danielsonkin: Legal matters aside, my EyeFi is fantastic. Not only does it work on the usual wireless networks, it creates it's own network when I am up in the mountains. To me, that's total magic! I like the idea of being able to upload immediately to my iPad and processing in Snapseed and then uploading from there to Smugmug; talk about unlimited capacity. What I don't get, is why would having the wireless capacity within card be superior or preferable to having it within the camera itself.

P&S cameras are already coming out with WiFi, smart phones with cameras have WiFi, GPS is already in the first cameras. Perhaps in 10 years Eye-Fi will be dead, it's main use at the end for older cameras that didn't have WiFi yet.

Reminds me of the Canon AF35M my parents had.... around 1980.
some similar design aspects. Maybe this is Canon's retro look?

Jman13: The color checker passport is, I feel, one of the most essential pieces of photography kit one can buy. It took my GH2 profiles from being a little bit green tinted to being dead on perfect, with rich, accurate color and is well worth the money.

Yes, I can see this one as more useful, to get the color balance right. (not just warm or cool), and if you print, you can compare to your print output

I wonder about this white balance approach with cards/cubes during capture. During film days, you never could adjust the white balance of a slide film. Yes, one had daylight and tungsten film, or one could put on filters to adjust color temperature. But overall, the human mind adjusts color balance, and white during a sun-set should just be more red than in white in the shade at high noon. I presume Pros still use a Color Meter to record the actual Kelvin when the picture is taken, but simply using a white/grey card, to set a scene shot at noon to the same white point on a computer screen as a scene shot in the evening seems wrong.

Najinsky: What's gone wrong with the test scene?

If you position the selection on the old ladies head just left of centre (as viewed), there are pronounced slanted yellow bands. The same thing is happening with the Olympus XZ-1 sample as well, but less pronounced.

It probably is some kind of moire. If it were due to lighting or shutter, it should also show up in other parts of the image.
I think it has to be a very specific moire that has to do with the original image of the old lady, there is some underlying pattern in yellow that creates moire with the pixel pitch of the Nikon camera.

Like for example ties with fine patterns on TV. The whole image of the tv presenter/studio is fine, but the tie (or whatever else the presenter is wearing) creates a moire effect, due to the specific pattern on the tie.
