both 18-55 and 50 1.8 are manufactured with the same quality... both doesn't have USM (smooth, quick and silent AF)... both are affordable...

Such a simple easy to use Canon EF 50mm f1.8 II, yet so many complications about this lens in this thread... sweet spot, 1.8, 5.6, flash, indoor, outdoor, low light, IQ, group shots, sharpening, "Manny Librodo" sharpening etc... you know what, I think you are just in love with your prime lens...

hehehe... admit it your are.. or partly... hihihihih...
My last say on this... don't over think and don't be so technical coz we are going nowhere here... do some experiments, try all the possible f-stops in any lighting conditions... start shooting...
