I already told you that my brother-in-law works for Sony on the Alpha project. Here is some more info, some is repeated from my previous posts. The advanced model will be 14.* MP and close to FF. It will have 1.25x factor and a switch for lenses with 1.5 factor. It will be called A300. Because of the pixel pattern similar to Sony ClearVid CMOS sensors, Sony will claim up to 2x effective pixel resolution. The flagship model will be called A500 and will be 100% full frame. Nikon is supplying Sony new steppers to create FF sensors in one shot. Sony first joined forces with Konica Minolta, now with Nikon. This gives to both Sony and Nikon advantage over Canon, which Sony believes will eventually drop to a 3rd place; Sony will move up to 2nd place in overall volume of DSLR's sales. The least expensive Sony DSLR will not have optical viewfinder and will be called A50. The flagship model will be 20 MP, 40 effective. That is the reason why Sony concentrates on top quality glass. Sony's advantage will be fact that they are the foremost sensor maker; their output is several times higher than Matsushita, which is second largest CCD maker.

This will allow Sony to eventually have 3 model groups, 2 models with 1.5 crop, two with 1.25 and two with 1.0. A50, A110, A200, A300, A400, A500, and A600.

I noticed that the moderator edited my post. Despite this you should know that the reason Sony opened their blog is because no Sony employees are allowed to participate in forums, unlike Matsus**ta's employees for example. The blog will allow Sony to communicate to the community directly from the management.

Interesting :-)

How will the CCD work if it can get twice the resolution, how can 1 pixel act like 2? Does it calculate the other pixels in between in a blok of say 8x8? I really like the idea of the cropped mode switch/button that could actually give a really broad lineup to choose from, that could be great.

Sony NEX-7 | Sony A55 | Dynax 5D | Dynax 7 | 7000AF | lots of Minolta and MF lenses

I am not sure, how it works. You should check info on the Sony site on ClearVid CMOS used in camcorders. It will be also used in the highly anticipated new XDCAM EX camcorder, which will be released this year. Sony practically owns the broadcast and the studio digital cinema market. Their main advantage is their sensor leadership and their patents in this area. They plan to eventually dominate the DSLR market too, in a distant future though. Neither Nikon nor Canon have their engineering and manufacturing expertise in this type of products, which is very similar to camcorders. Canon in its camcorders relies on Sony and Matsus**ta CCD blocks, chips and tape and DVD mechanisms.

I think that ClearVid has the pixel rows at 45 deg. It's a checkerboard pattern. It not only scans this pattern horizontally, but it also interpolates info from neighboring pixels at points where the 4 pixels meet, creating a virtual pixel. I am not really sure, but this is how my brother in law explained it to me at one point. I think that the points it reads are corner of a pixel, center of a pixel, next corner; the next scan line reads top corner of that pixel. The corner is actually asgveraged info from 4 pixels.

ClearVid CMOS is :
rotated by 45 deg (same way as Fuji)
1R and 1B pixels per 6 greens (ie 6:1:1), while traditional Bayer is 2:1:1

Regarding the 6:1:1, the idea is basically to keep the same color resolution as now, while increasing the luminance resolution (as luma is mostly using green information)

note: I also think that such a disclosure of information (with what would obviously be a severe breach of non disclosure agreement) is a bit strange. When under NDA, it means non disclosure to anyone not covered by the same nda, thus no disclosure to family.
I would perfectly understand if this thread was removed to protect the Sony employee.

I fully agree. But that would then also apply to other threads in which similar disclosures were made by the same person.

I think that it is different than in the video cameras - I mean the percentage of the green pixels - I am not really sure and can't find out anymore - but the diagonal pattern and the scanning process is the same. I am under no NDA, and believe me, there are so many concepts and prototypes going on within the Alpha project that no one is really sure how things will shape up. One thing is sure and that is that Sony is determined to use its technological advantage to dominate the market at time when there will be better marriage of photography and video. Just as now a cell phone has many functions, this concept will be carried into the future imaging products. One of the things they are working hard on is 3D TV that works without glasses, and as electronic display technology will replace photographs in the future, guess what? Already now there are prototypes of 3D cameras being developed by Sony.

The 2 DSLR prototypes that were shown at different shows by Sony were no wooden mock ups, but the actual cameras that will be produced. The same goes for the lenses. All these were pretty much final prototypes, but Sony could not disclose this due to its competition. The main thing that is holding these projects up is development of SSS which has to work harder with larger sensors; the insides of the cameras may be a little different than on the prototypes shown, not the outsides. That was finalized before showing them to the public.

Sony was originally going to buy the Contax brand from Kyocera, but then used this info in its negotioations with KM, from whom they managed to get the DSLR division with all its expertise for pennies on the dollar. KM really wanted the DSLR division to be in the best hands; they cared about it more than about anything else; the Minolta portion of the KM team wanted to see the legacy of the system to continue and to improve as much as possible. The decision to sell to Sony was rather emotional.

A lot of consistency in the story!

The main shortcomings of the current system are noise and only one affordable ssm lens - what about that ?

same way as Fuji


I hope this isn't true...have you ever try to get sharp images from Fuji's pictures; absolutely no way; colors and dynamic range is good (if not even the best), but sharpness is awful.....

It depends on the sensor type. Fuji has a sensor with high dynamic range and lower resolution and a sensor with high resolution (used in the 9600).The second one is sharp.

If true then those cameras will be monsters. Lets hope he has great info!

Mr. Mizumi,

Thanks for the interesting thread. I hope you understand people's suspicions. Fascinating info, but hard to believe that an employee would be free to disclose it so freely to a relative, and then that relative would be free to tell the general public; given the level of secrecy Sony is exercizing in general.

So just a few questions. Are you really Japanese? Your profile is virtually blank. Do you live in Japan or somewhere else? If you are Japanese, your English is very good and suggests an education in English. Does this brother in law who works for Sony give you all this info casually, over a beer or two, or is it something else?

Why does your inlaw feel free to give out all this info when every other Sony employee is tight lipped? Are you betraying his trust by publishing the info on this forum?

Sorry for all the questions. Just help me see this all in a more credible light, since it would be great if the info is accurate!

Of course, this post suggests that other Sony employees are liars, since I recall those employees at PMA stated that the mockups were just wooden bodies.

One fraud vs. many liars?
