I keep hearing about the better tonal range of larger format chromes/negs. I don't understand it really. Isn't the tonal range a function of the film/paper mainly and to some degree of the lens? And since smaller format lenses are often better (coated, resolution, etc) then large format older ones and the film emulsion is the same, how/why is the tonal range better in the larger format? I currently shoot chromes in 6x9 and 35mm and aside of the more detail in the 6x9, I didn't notice any difference in the tonal range (same emulsion, same shot).
