| more myth than fact. so here is how it works... technically a smaller sensor has smaller pixel sites. however if you stop here you are wrong. this completely fails to take into consideration then lens in the equation, especially if the lens is made for that sensor size. as example, a 1/3" camera matched to a 1/3" lens. the 1/3" lens condenses / shrinks the image size for that sensor. this increases the photons/mm - another words it makes the image projected on the sensor smaller and brighter. this in practical effect compensates out for a loss of sensitivity due to smaller pixel sites. this is exactly what the metabones adapter does - it projects the lens's rear image projection down into a smaller area, making it brighter ( increasing photons / mm ). this is what makes for that 1 stop increase in brightness. its simple math and physics, nothing more. therefore if you use a lens properly matched to the sensor, sensor size becomes far less of an issue in terms of sensitivity.
