Q: Next generation sensors?
Seems to me that the current gen. sensor size and pixel count (2/3" and
8Mpix respectively) have pretty well maxed out, for the non-dslr cameras. Anyone have any idea-read something about the next generation?? Bigger size, more pixels, new tricks?? TIA |

TIA I guess one "new" trick is what fuji does by having differently sized pixels for increased contrast ability. Lots of Greetings! Volker |

Volker It that like their diamond shaped sensors that produced double the physical resolution? Or maybe it's like their current technology that uses octagon shaped sensors to increase the chroma resolution. I wouldn't take Fuji's "technological breakthroughs" too seriously. The multiple sensor size trick sounds old to me. I'm sure I heard about it three years ago when sensor noise and dynamic range were crippling problems. The new technologies that I forsee a Camera body size reduction. Improved battery life. Large, high quality sensors becoming affordable. Higher ISO ratings by improving light gathering. Better image quality in tough conditions. Faster autofocus. Consumer feature integration- wireless, video, music, phone, P2P, etc. |

Large, high quality sensors becoming affordable.
This is a tricky one. Electronics generally reduce price by shrinking the dimensions of a chip, allowing for higher throughput in manufacturing with lower defect rates. So it is unlikely you'll get bigger physical dimensions on the sensor chip AND have it be cheaper. If this were possible I think you'd see more full-frame (35mm) sensors in prosumer DSLRs. You may see however, that they will keep cranking up the number of pixels on the same size sensor. Not sure this helps with better ISO's light gathering etc. "Kevin McMurtrie" wrote in message ...

TIA My guess is that you will see larger sensors with same pixel size, increasing number of pixels on chip. But the economics will mean the growth will be relatively slow. I think you will see prices continue to drop on cameras, and other features improve, and that will drive market more than any fundamental changes in the chips. |

Not sure this helps with better ISO's light gathering etc. Quite - and as the dimensions of each transistor get smaller, the cost per square mm goes UP (due to equipment costs, maintenance, running cost, cost of purer finer materials, etc, etc...). Defect density is king and clean rooms aren't expected to get much cleaner in the foreseeable future. Cost per transistor goes DOWN - but for high quality sensors, that's not neccesarily what we want. |

It depends what you mean by "affordable". If one has the glass, US$3000 or US$3500 is affordable for some folks. Given that a 36 x 48mm medium format back is US$10,000, it seems to me that a 36 x 24 mm sensor camera ought to be around US$3000. You may see however, that they will keep cranking up the number of pixels on the same size sensor. Not sure this helps with better ISO's light gathering etc. Don't forget dynamic range. Small-pixel cameras (e.g. FZ10, D2x) can produce high-contrast/short tonal range images that look great but if you need to capture a longer tonal range, you'll be unhappy. But there's no reason the D2x sensor should be any more expensive than any other 1.5x sensor, so we can say goodbye to quality low-ISO imaging in the low-end dSLRs once Sony gets their fab line ramped up and Canon responds with a 12MP sensor of their own.

Given that a 36 x 48mm medium format back is US$10,000, it seems to me that a 36 x 24 mm sensor camera ought to be around US$3000. Maybe. I'm of the opinion that those who buy cutting edge technology (like, for example, full-frasme DSLRs) subsidize the R&D more than those who by the more prosaic P&S cameras. That means the cost of the parts that go into the full-frame DSLRs is a lessor part of the selling price than in the P&S cameras. This happens in most undustries. The buyers of SUVs pay a price premium; the buyers of Plasma screen TVs pay a premium over the price of a CRT 25: TV; and on and on. Saying that a full-frame DSLR sould cost $3,000 doesn't take this premium into account, IMO. Of course, this is for NOW. In 5 years, this could change, as another feature defines the high end product. -- Bill Funk Change "g" to "a" |
