I'd like to be able to take better photos.
My gearhead wish is for a decent compact for serious photographers. A fixed, short lens with a big sensor and fast turn-on time. Imagine a 35mm equiv lens with a 1.5x crop sensor, f/2 or faster. Now put it in a small package with a fast turn-on time, ideally "instant" like many DSLRs. With a wide aperture focus could be snappy, and the big sensor would give low noise even at 1600ISO or so. But 24mm real focal length and f/1.4 is 17mm aperture, with a 24x17mm sensor so a 25mm thick camera should be able to have that lens built into it. You might have to screw in a lens hood if you wanted that.
What limits would I expect? SD cards and 2-3 fps strike me as likely, to keep size down and battery life up (small, slow cpu). Probably 6MP-8MP, likely the sensor out of the 350D or 50D depending on who makes it. Probably laid out like the small video cameras, possibly even with a flip'n'twist screen. Sheesh, if Panasonic can put a
3CCD HDTV video camera into this package, why can't we have a still camera like that?
(yes, I am tempted by that camera)
