I've often idolly dreamt of setting up a company to make these hitherto undesigned cameras and it's occured to me that there is the expertise on these forums to do this....Ray knows about optics so we've got a lens designer, Richard Chang is working on a black and white digiback so I guess he knows about sensor design stuff and I'm sure somewhere I read Michael held patents for things and you get those for designy inventy type stuff right? I'll be the dolly bird in the adverts since I can contribute precisely nothing technical to the designs.
Nice idea and thanks for the flattery, but Ray wouldn't have a clue how to design a lens

. I've never used the software and I've never even read a book devoted to lens design. All my knowledge of lenses is of the general type; the relationship between f stop and DoF; the relationship between diffraction and resolution etc.
However, I agree that the choice amongst P&S digicams is bewildering. It seems that almost every model has a least one advantage over another, whether it be merely price and weight, but so many disadvantages it's almost impossible to make a decision.
The ideal P&S would be one that incorporates
all the good points that already exist in the hundreds of different models, but that really wouldn't be possible because of patents, I presume. The Canon S70 mentioned here, for example, has a lot of noise at ISO 400, much more than the lighter and more compact FinePix F30.
Image stabilisation is now a must. If the compact P&S is to be your main camera for all purposes, then a RAW mode is also very desirable. For my purposes, lack of a RAW capability with its long write time is not such a big issue and, if given a choice between RAW and image stabilisation, I'd choose IS. In fact, for all shots where freezing subject movement is not a priority, an IS capability is the equivalent of a low noise, high ISO, as in the FinePix F30.
At the moment, my ideal 'ultra' compact P&S would be the Sony DSC T30 with the low noise of the FinePix F30 and the aperture and shutter priority modes of the F30. RAW would be icing on the cake.
