What's your feeling about this one :
Canon IXUS 155, 20 M pixels, 142 grams, no CHDK yet, but "Continuous Shooting Approx. 0.8 shots/sec. (until memory card becomes full)"
For a fine 20M picture, 7 Mb, that is more than 2000 pix in a 16G memory card. Largely covering a 30 min flight.
Do we really need interface with flight controler or CHDK scripting ?
In addition, it will probably be CHDK enabled within weeks anyway.
