And your source is???

8MP? That means one of 3 things:
- 4/3 type sensor (don't hold your breath);
- 2/3 type sensor (most likely scenario - would mean that resulting focal length of 10X C-7xx series would likely be more like 32-320 or 28-280, rather than 38-380 or 42-420);
- 1/1.8 type? Is this even possible? Noise levels would almost certainly be prohibitively high above ISO 200; and probably objectionable at ISO 100.

Sadly, Oly succumbs to the great megapixel race mentality. They should have attempted to transplant a 6Mp version of the 4/3, with improved dark current management.

It will be interesting to see if they are introduced at PMA. Waiting for Steve and others to review cameras.

A "noise free" 8Mp 1/1.8 type CCD? I'll have to see it to believe it. I was sure Oly would field a 2/3 type and offer users a more flexible focal length. Nice fast lens, but they still haven't figured it out - tiny sensor and too much telephoto at the expense of a wider wide for landscapes and group shots. With IS, I'm guessing the MSRP will probably be $750.

BTW, crazyme, where'd you get the specs?

It came from the same source who leaked the Minolta A2 & Z2 and Canon Pro1 , S1 & S2. And those were right on the money.

Oly is supposed to be using a new processor and noise reduction system to keep the noise out. They wanted to put an emphasis on keeping the cameras light with fast lenses, so they did not go with a larger sensor.

I'm not trying to argue with you, crazyme, but a larger sensor would have only a nominal effect on the camera's weight.

A CCD is essentially a chip with millions of "wells" on its surface - and a photodiode at the bottom of each well. They employ microlenses atop each well to collect more photons and channel them down the wells and towards the photodiodes, where they are converted to electrons and then transfered to a register for processing into a picture. 8Mp on a type 1/1.8 = extremely small "pixels" and pixel pitch (the distance between pixels). The smaller the pixel, the smaller the area to capture photons. Hence a lower signal strength. Usually not noticeable in pics taken in daylight, since there are sufficient photons to find their way down even a small well. But low signal strength really rears its ugly head in lowlight, where far fewer photons are able to make their way to the photodiodes.

Noise is a function of pixel pitch, the type of registry employed in the design, the physical properties of bulk silicon, and the physics of electron activity. Noise is present in every chip. Some designs effectively reduce, but do not fully eliminate, noise.

The key to acceptable noise levels is larger sensors with larger wells, larger photodiodes, hence higher signal/noise ratios. Oly's "processing" would have to emply more than mere dark-frame subtraction to effectively reduce the noise that will be generated by a CCD of this type. It would have to rely on interpolation. I will reserve judgment until I see the specs, reviews, and sample pics - but I'm not holding my breath.
