I know all the messages in here show great excitement as well as worry, about the new Sony F717.
People are worried that their $1000 investment in the F707 will be made obsolete by new technology.
I'm sure that Sony has made some minor improvements with the F707. But when it comes to camera BASICS, like picture quality, the zoom reach and aperture of the lens, I think the F707 is as good as its going to get.
Here is my analysis:
The reason why the F707 has so many compelling features for only $1000 (and some have paid a lot less than that) is because of its small sensor size. The F707 CCD is tiny compared to 35mm film (which is 24mm by 36mm--why do they call it 35mm?). This enables Sony to design a lens that has such a long zoom range yet still is fast (F2 to F2.4). There is no comparable lens in the 35mm world. The Canon 28mm to 70mm F2.8 L lens costs more than $1000 (maybe $1500) and by itself weighs a lot more than the whole F707.
Because the CCD is so much smaller than film, the lens has to be of extremely high quality to do as good a job as the Sony does. I'm sure the reason why Sony gets higher resolution figures than any other digital camera is because of the high quality Carl Zeiss lens. It is probably the CZ lens which also enables the Sony to have more saturated colors.
In order to make a camera with more pixels than 5 million, Sony will have to either make bigger lenses, or people will have to settle for a much more modest lens, or more likely both will happen. The cost of the camera will go up because the glass will be bigger and more expensive. And then the camera will be priced out of reach of the target audience.
With 5 million pixels already enough to produce very high quality 8 x 10 prints (as anyone who has printed a Sony F707 picture can attest to), 5 million pixels may be the end of the line in the prosumer all-in-one category.
The future, for those who want higher quality than the F707, will be full frame (that is CCD the same 24mm x 36mm size of 35mm film) SLR cameras that are AFFORDABLE. There is a rumor elsewhere that Canon is going to announce such a camera... a much more signficant rumor than the rumored F717.
I should add that there's nothing magical about the 24mm x 36mm size; but no one wants to design or buy a whole new lens systems for a different sized CCD.
