Transmittance or T stop is very important mainly for lenses desiggned to be used in low light, you might pay plenty of extra $$$$ for a f1.2 lens over f1.4 lens for low light performance to discover that both are equal or worst the f1.4 lens has a lower T value and thus transmits more light 
can the transmittance be measured her in our tests ?? 
DXO is doing it so it is feasible
