That's true. At the end of the day its the sensitivity of the sensor to light that matters (QE - what percentage of light hitting the sensor is converted to a signal?).
Early model DSLRs QE is on the low side of around 25-35%. Some later models have quite high QE. The Sony Exmor sensors are currently the highest
ie. in Sony cameras like Sony A99, RX1, Nikon D800, Nikon D600.
