Panasonic is long known for 3CCD and 3MOS products.
As I understand that you don't need antialiasing filter in case of three slightly displaced sensors.
And I absolutely agree with prism efficiency.

Interesting. Do they use 3 seperate image sensors, or one sensor with pixel level prisms?
I think it is very expensive and much harder to make a prism that can transfer whole frame without any distortions, precise alignment and sharpness, especially to match still imaging quality requirements, than a a smaller prisms that just have to split single light ray/pixel.

As you said color resolution is not that important.. I wonder if there is anything like YCrCb sensors, that would directly produce 4:2:0 image.

Sensor capturing more light and having half the linear color resolution (and probably more colour noise and less dynamic range).

From 1/6" up to 1/3" are used in their camcorders.
I think they are masters in this.
As well as very good optical stabilization for cheap.

I actually would like a 6MP camera with excellent ISO6400 or even ISO12800 capabilities. It would be even better if I could switch between this and 15MP in the same camera.
That would work for me !

You need interchangable sensors then.
One for low resolution and high iso, another one for high resolution, low iso and low fps.

You can use pixel binning on higher res sensors to accomplish something similar.

It's called the 5d mk2, or the d700, but you throw out ergos and affordable glass

Why'd you buy a 5d Mk2 if you're so displeased with it?

Cause I gotta admit the IQ and hi iso from it just rocks, it's called deal with the crap build and ergos for 21mp and usable in BIG 2x3 ft prints at 6400 iso.

I'll still moan and whine about the rest of the camera tho yeah I want a k7 with this sensor in it but that won't happen.

It isn't stopping yet my friends. Looks like Nikon are coming out with a 30.2 megapixel Full Framer the D4X..Well that is what I read at least. Seems some info got through before it could be shut down.

No, I think you may see 50 megapixel 35mm format cameras within the next three to four years.

not sure if it has been discussed, but the sensor technology in the Fujifilm F200EXR would be interesting applied to a APS-C sensor.

I personally think that the upper bounds of MP of APS-C is being reached. I think the future will hinge on the technology side of things...

The circuitry will get smaller, the sensor sites will get bigger (Canon has already done this)

There will be more concentration on dynamic range and sensitivity (Fuji and Nikon).

More will be done on sensor (aka as CMOS).

Who will do this? My bet is Samsung. They are a technology company aligning their efforts to make a jump into the serious side of photography on their own. Fuji has already said that their focus is going to be P&S and have broke ranks with Nikon. Give it two years.
It is gonna be interesting to see for sure.

15 MP is fine for me. I hope next general focus from the camera companies will be dynamic range

I really wonder when it is that anyone would need >30Mp...
Do even billboard-size prints really need that kind of resolution? Maybe, though how close do people stand from them to judge pixellation?

If digital media technology doesn't come to the party, then there's gonna be some serious storage problems...

Well if not considering all other factors (reasonable readout speed, heating, memory, optic physics and similar), then if current 1/2.33" sensor 12mpix cameras have 43 mp/cm2 pixel density, with current sensor manufacturing technology you can squeeze 3.6x2.4=8.64*43=371.52 Megapixels.
Practically it could be next to impossible to manufacture in a reasonable way, but the most straightforward way would be just stiching enough 1/2.33" sensors.

Even if the noise would be as horrible as it is with P&S at such resolution, you could apply even more agressive noise reduction than P&S use and get something like perfectly clean (it would still have bad DR and distorted colours) 100 mpix effective resolution.


BTW, if you have a similar P&S camera you can try this out already now, by stitching a panorama of 35 frames arranged in similar manner:

They don't. Billboard images must be viewed from at least 5-6 meter from the image minimum and they are printed at 18-32 dpi.
