the digital camera technology is maturing and the advances are less radical and slower than in the past.
Very good point. When people point to past history to predict future releases, they seem to ignore that digital cameras have not been around very long and that in the early stages of any new technology, there are usually some massive leaps in the first few years, followed by incremental changes as the technology matures.
A manufacturer of any product has to balance out the benefits of adding incremental improvements against the cost that results from the changes required in the production of the product.
Reading this forum should give people some idea of what Canon and other manufacturers are up against. People want new technology and they want it NOW! But they also want some really incredible and in many cases contradictory features.
If one were to distill the demands seen just on this forum, it might be summarized as a full frame, digital SLR that can take pictures in near total darkness, at extremely high ISOs with no discernible noise, while at the same time producing high definition video that eliminates all moire patterns. When shooting a landscape, you should be able to clearly make out sunspot details, while also retaining detail on the underside of any rocks in the foreground. The sensor should be about 50 megapixels, except for those who don't want more megapixels, in which case they should offer a sensor that has fewer megapixels than current models, so that these customers can edit photos on a 10-year-old laptop running Windows 95. The camera should be fully weather-sealed. Its autofocus system must never produce an out-of-focus image and it must be able to do so at a dozen frames per second. Autofocus should be available for video, except when it isn't needed, as which time, pull focus should be much easier to accomplish. Oh...and it's supposed to cost about $2,500 U.S.
While I'm getting a little tired of all the whining about what Canon HAS TO DO, I think I'm really dreading the whining that we'll hear when Canon finally releases it's next round of cameras and people start complaining about what it doesn't do.
