not sure but not likely by comparing 24 lux vs 24 f2.8 @2.8, 21 lux vs 21 f2.8 @ 2.8, 35 lux vs 35 f2 @2
not likely because image quality is almost never better @max apperture of the little brother, sometimes the same and sometimes the lux will loose, but lux call for double price and a lot of dead weight
not sure because sometime we definitely need f1.4 to take a shot
worth it or not, personally call, but not "one step there", for me, it is more likely a trade off
