Digital Photography for Standard Cameras?

NightWhistler asks: "I've been hearing stories for some time now about digital modules that can be used inside normal photo camera's as a sort of 'digital film', effectively turning a standard camera into a digital one. If they exist and performance is good, I would love to get my hands on one of those babies... ;-) Has anyone actually seen one of these, or perhaps have experience with them?" There may have been one company that did this, but I think they went out of business, recently. I've always thought this was a neat idea, but is there really a market for this kind of modification?

Digital cameras offer little control

[Twylite]

I'm not a serious photographer, but the ability to have full control over focus, aperture and exposure is important to me. I have found few digital cameras that will admit to being less intelligent than me in this regard, and none which allow (physical) aperture control.

I have done a fair amount of nature photography, especially birds. For a non-digital camera, aperture and film speed are critical. Optical magnification (as in a 2x or 4x converter, as opposed to a longer lense) is almost out of the question because each filter makes you lose 1 or 2 f-stops, which means a longer exposure and more chance of movement.

I have yet to find a digital camera which can adequately address this problem. They all use magnification filters instead of telephoto lenses so that they stay compact, and most only have digital compensation which they claim is aperture control.

A CCD which fits in place of a normal 35mm film would be a great way to get high quality photographs.
