Back when Minolta existed as a camera company - and had a couple of digital lines, one of their cameras had a brilliant feature: hold the shutter down and the internal buffer would fill, and once full each new shot would replace one of the older ones, but once you lifted your finger from the shutter, everything in the buffer, the last couple of seconds was written out to the CF (or whatever the storage device was).

They never put that feature on a DSLR, sigh.

FWIW, Minolta digicams used Sony sensors. When Konica swallowed Minolta, the camera division was sold to Sony which was moving from just making sensors - so you can still buy a camera with some Minolta heritage.
