Well, it's not small. But it wasn't a (big) problem; it might be difficult to fit the whole system (camera + recorder) inside a small car; but that's because of the recorder + UPS to power the recorder. I have seem footage shot from a minivan.
I have not seem Genesis footage yet. But Genesis is able to output only 10 bit compared to 14 bit of Dalsa. Dalsa is probably getting closer to film quality in terms of lattitude.
