Prev: I bet no one knows enough to answer THIS question... !
Next: I've read about "adaptive optics" as used by the US military,intelligence agencies, etc in satellite imagery, but what about using opticsto correct out of focus pictures? Is this possible?

Sensors are more dependent on newer forms of technology than size. Newer technology is always used in compact and superzoom cameras 3-4 years before they ever make it to larger sensor cameras. > optics, Like you don't. Due to the smaller sensor in these cameras they excel at macrophotography for their longer DOF available. Due to the smaller sensor size much larger apertures are available at longer focal lengths (precisely what the professional wildlife photographer requires) than any that can ever be made available for DSLR glass. Due to the smaller optics sizes, they are and must be figured to diffraction-limited precision. The very best optics that can exist. Unlike DSLR glass that is only sharp at one aperture, and rarely if ever will DSLR glass afford pixel-level detail resolution, which is common on smaller sensors matched to finer optics. > focusing systems, We are all too aware of focusing systems and the benefits of each. Phase focusing might be faster, but it's highly inaccurate. Contrast detection is precise. I'd much rather walk away with 90 out of 100 images properly focused than 10 out of 1000. >dynamic range, See above about sensor technology. One of my smaller sensor cameras has a dynamic range of 10.3 EV steps. That's 3-4 more EV steps of dynamic range than film. That's more than anyone needs. > viewfinders, Yes, you don't realize that electronic viewfinders are much more reliable, versatile, and useful. They can display a real-time shutter-speed preview. You can zoom into the pixels for accurate focusing. You can tell in real-time if your image has the proper white-balance and exposure, BEFORE you press the shutter, not after. The uses for an EVF and LCD are immense. They can also be used to frame and focus in light levels so low that an optical viewfinder has become totally useless long ago. There's so much you don't know about them because YOU'VE NEVER USED THEM. > or photography in general, Like you don't. Because you don't even own ONE camera. We've proved that time and time again. >and they don't want to learn either. Like you don't. Being the incessant pretend photographer troll that you are, you won't even buy a camera to find out just how wrong you've been all your life. > They may be >disappointed with their equipment in terms of lag times Lag times in compact and superzoom cameras are now even shorter than in DSLRs because they don't have to move those cumbersome mirrors and loudly slapping, image jarring, mechanical contraptions out of the way. > and low light >performance, My superzoom cameras can image stars down to magnitude 9.2.

Our >favorite troll is ample proof of this. You being the main demented role-playing pretend photographer troll around here. How's that computer controlled geyser that you helped to install in Yellowstone? Been back there yet to work on it? <http://www.wifi-forum.com/wf/showpost.php?p=448381&postcount=101> If anyone wants to see just how fuckingly psychotic that you are and how much you like to role-play online in your imaginary world, that's a fun read. LOL!

I doubt it. You do have the additional assembly time of the lens, but you don't have the mechanical assembly of viewfinders or shutters (if they lack a mechanical shutter). The cameras are all assembled in very low wage countries.

Couple it with the TINY sensor, and it screams, "waste of space, weight and dollars."

There are buyers that believe that bigger is always better.
